Perfluorocarbon Liquid in Traumatic Vitreous Hemorrhage and Retinal Detachment
Authors: Desai Uday R , Peyman Gholam A , Harper C Armitage
Published: April 2021

ABSTRACT

Patients with penetrating ocular trauma also may have severe vitreous hemorrhage and associated retinal detachment. Removing the hemorrhage and repairing the detachment can be a difficult surgical problem. Besides the limited surgical view due to the hemorrhage, an incomplete separation of the posterior hyaloid membrane can allow the detached retina to be drawn toward the port of the vitrectomy instrument, producing an inadvertent retinal tear. We have used perfluoroperhydrophena nth rene (Vitreon) to manage three cases of penetrating ocular trauma with concurrent retinal detachment and a partial vitreous detachment, either at the time of surgery or as noted ultrasonographically. The perfluorocarbon liquid helped to separate the partially detached posterior hyaloid membrane and flatten the detached retina. This maneuver simplified removal of the vitreous hemorrhage and management of the retinal detachment.
Postoperative Refraction and Anterior Chamber Depth After Complicated Cataract Surgery With Vitreous Loss and Transscleral Suture Fixation of Posterior Chamber Lenses
Authors: Mittelviefhaus Hans , Janknecht Peter
Published: April 2021

ABSTRACT

The postoperative refraction and anterior chamber depth of 50 eyes that had complicated cataract extraction with vitreous loss were compared with those of 25 fellow eyes (that had uncomplicated cataract extraction) of the same patients. Transscleral suture fixation of the posterior chamber intraocular lens (PC-IOL) was required in 34 of the 50 study eyes; the lens was implanted onto the remaining defective capsule in the remaining 16. The anterior chamber depth was significantly deeper after transscleral suture fixation of the PC-IOL (mean, 0.54 mm; P< .01 ). The difference between the refraction of the eyes with transscleral suture fixation and that of the control eyes was +0.58 diopters. Although each surgeon should assess specific results and modify the lens calculations accordingly, we have found that with our technique, for eyes that have required transscleral suture fixation of a PC-IOL, +0.50 D should be added to the calculated IOL power.
Acquired Blepharoptosis Secondary to Essential Blepharospasm
Authors: Bodker Fred S , Olson Jane J , Putterman Allen M
Published: April 2021

ABSTRACT

We treated four patients with essential blepharospasm, receiving botulinum A toxin, in whom, although they had no preexisting blepharoptosis, a concurrent bilateral acquired blepharoptosis developed. Since the blepharoptosis did not improve after the period of time during which the effects of botulinum A toxin would have been expected to resolve (2 to 10 weeks), we judged that its development was unrelated to the toxin. We propose, rather, that the stretching, attenuation, disinsertion, or dehiscence of the upper eyelid levator muscle caused by the blepharospasm were at least partly responsible for the onset of the blepharoptosis. To ensure appropriate treatment in these cases, careful clinical evaluation is required to differentiate the two conditions.
Subretinal Hemorrhage After Grid Laser Photocoagulation for ldiopathic Juxtafoveolar Retinal Telangiectasis
Authors: Friedman Scott M , Mames Robert N , Stewart Michael W
Published: April 2021

ABSTRACT

A 56-year-old man had decreased vision secondary to bilateral idiopathic Juxtafoveolar retinal telangiectasis. One month after grid laser photocoagulation for macular edema in the right eye, a subretinal hemorrhage developed. Over the next 2 months, the hemorrhage spontaneously resorbed and vision improved to 20/50. At 2-year follow up, without further treatment, vision was still 20/50.
Dynamic Documentation of Digital Dacryocystography
Authors: Steinkogler F J , Huber E , Karnel F , Kuchar A
Published: April 2021

ABSTRACT

Digital dacryocystography has proved to be the optimum method of x-ray diagnostics in connection with managing obstructions of the lacrimal pathways. We present 50 patients in whom digital dacryocystography was performed with a computercontrolled x-ray unit and a C-arc coupled to an image intensifier TV-system. A nonionic water soluble contrast medium was used. The bilateral contrast medium filling process appearing on the monitor was simultaneously recorded on videotape. Vidéocassettes, with patient data attached, were stored in a videotape library, providing repeatable diagnostic documentation and an excellent base for scientific analyses.
Association Between SurgicallyInduced Astigmatism and Cataract Incision Size in the Early Postoperative Period
Authors: Leen Martha M , Ho Charles C , Yanoff Myron
Published: April 2021

ABSTRACT

One hundred sixteen eyes with cataracts were prospectively randomized into four surgical groups. Silicone and polymethylmethacrylate (PMMA) intraocular lenses were implanted into the posterior chamber of these eyes through 4-, 6-, or 11-millimeter incisions by one surgeon. Surgically-induced astigmatism was evaluated in terms of: (1) the proportion of eyes achieving a refractive cylinder of 1 .5 or less, without regard to axis; and (2) the induced cylinder, with regard to axis, using vector analysis. One week postoperatively, the eyes with a 4-millimeter incision had a significantly lower mean induced cylinder than those with larger incisions (P =.019); and all three phacoemulsification groups had a significantly higher proportion of eyes with a cylinder of 1 .5 or less than the nuclear expression group (P < .01). One month postoperatively, the 4-mi Ui meter-incision group had a significantly lower mean induced cylinder (P = .044) as well as a significantly higher proportion of eyes with a cylinder of 1.5 or less, than the larger-incision groups (P = .05). Three months postoperatively, no value of any parameter in any group differed significantly from that of that parameter in any other group.
Effects of Cycloplegia and Iris Pigmentation on Postoperative Intraocular Inflammation
Authors: Onodera Tsuyoshi , Gimbel Howard V , DeBroff Brian M
Published: April 2021

ABSTRACT

Using the Kowa laser flare cell meter, we investigated the relation between anterior chamber inflammation following phacoemulsification and posterior chamber intraocular lens implantation, and (1) iris color and (2) the use of 1% cyclopentolate hydrochloride for 1 week postoperatively. One hundred sixty eyes, randomized into either a cycloplegic or noncycloplegic group, and classified into four different iris color groups-blue, brown, green, and hazel-were studied. Eyes with brown irides had significantly more intense flare 2 weeks postoperatively than eyes with blue irides. Overall, postoperative flare tended to be related to the degree of iris pigmentation. Use of 1% cyclopentolate hydrochloride for 1 week postoperatively failed to decrease anterior chamber inflammation in any of the eyes.
Canaliculorhinostomy Following Dacryocystectomy for Removal of a Benign Fibrous Histiocytoma of the Lacrimal Sac
Authors: Older J Justin , Sims Leslie M
Published: April 2021

ABSTRACT

A 41 -year-old woman had epiphora and a right lacrimal sac mass. A solid mass filling the entire lacrimal sac was found at surgery. After a month of testing and evaluation at the Armed Forces Institute of Pathology, the final diagnosis was benign fibrous histiocytoma.

A dacryocystectomy was performed, and the entire tumor was removed. The area of the common canaliculus was then attached to a nasal mucosal flap, and the system was intubated with silicone tubing for 1 year. Two years after the tubing was removed, the epiphora had resolved and there was no recurrence of the tumor.
Semicircle Flap Reconstruction "Plus"
Authors: Boynton James R
Published: April 2021

ABSTRACT

The semicircle flap is an excellent method for reconstructing upper and lower eyelid defects. The procedure may be combined with recognized techniques such as skin grafts, tarsal flaps, and other surgical manipulations. Five such additions to the semicircle flap are described. These combined techniques can expand the range of the procedure, increase its versatility, and improve the results.
Two-Step Annular Tectonic Lamellar Keratoplasty in Severe Terrien's Marginal Degeneration
Authors: Hahn Tae Won , Kim Jae Ho
Published: April 2021

ABSTRACT

We present a case of severe Terrien's marginal degeneration treated with two-step annular lamellar keratoplasty. Both eyes of the patient had peripheral corneal thinning with ectasia around the entire corneal circumference. First, an annular-shaped ectatic lesion was defined and removed, and donor tissue of the same size and shape was sutured on the recipient bed with 10-0 nylon. Four months later, the same operation was performed in the fellow eye.

This procedure allows corneal astigmatism to be controlled either by suture removal or resuturing, thereby substantially improving visual acuity. No complications occurred during 1 ½ years of follow up.
Low-Tension Glaucoma: A Comparative Study With Retinal Ischemic Syndromes and Anterior Ischemic Optic Neuropathy
Authors: Müller M , Kessler Ch , Wessel K , Mehdorn E , Kömpf D
Published: April 2021

ABSTRACT

In low-tension glaucoma (LTG), nerve-fiber-bundle defects are assumed to result from ischemia of the choroidal branches of the posterior ciliary arteries, due either to local vascular changes or, presumably, hemodynamically occlusive carotid artery disease. To study the possible hemodynamical origin of LTG, we examined and compared, clinically and by ultrasound (continuous-wave Doppler and duplex-scanning), the extracranial carotid arteries of (1) 21 patients (34 eyes) with LTG, (2) 48 patients (49 eyes) with retinal ischemic syndromes (RISI, and (3) 15 patients (17 eyes) with anterior ischemic optic neuropathy (AION). High-grade stenoses and occlusions of the internal carotid arteries ipsilateral to the affected eyes were significantly more frequent in the RIS patients (17 of 49) than in the LTG patients (2 of 34; P < .01) and the AION patients (0 of 17; P < .01). Among our relatively small group of LTG patients, we found no striking evidence supporting a hemodynamic origin of LTG.
Necrotizing Scleritis and Transient Myopia Following Strabismus Surgery
Authors: Gross Steven A , von Noorden Gunter K , Jones Dan B
Published: April 2021

ABSTRACT

Necrotizing scleritis may occur following ocular surgery, most commonly after cataract extraction. This complication developed in a 60-year-old woman following strabismus surgery for a gaze palsy and sixth-nerve paresis following a stroke. Although an autoimmune process is present in many patients with necrotizing scleritis, none was detected in this patient. Inflammation was controlled with topical and systemic corticosteroids and ibuprofen. Good visual acuity was preserved, and improved ocular alignment was achieved. Transient myopia, not previously reported in necrotizing scleritis, was observed.

Clinical Presentation and Initial Treatment Patterns in Patients With Exfoliation Glaucoma Versus Primary Open-Angle Glaucoma
Authors: Konstas Anastasios G P , Stewart William C , Stroman Gesa A , Sine Cheryl S
Published: April 2021

* BACKGROUND AND OBJECTIVE: The presentation and initial response to treatment of consecutive patients with exfoliation glaucoma (PXE) and primary open-angle glaucoma (POAG) were evaluated prospectively.

* PATIENTS AND METHODS: Forty-six consecutive newly diagnosed patients with POAG and PXE were included in a prospective study that evaluated the initial clinical course and treatment results. The two groups were age- and race-matched.

* RESULTS: This study found no difference in optic disc parameters at presentation between patients with POAG (n = 22) and those with PXE (n = 24) (P > .05). However, the presenting mean defect was significantly worse in patients with PXE versus those with POAG (P = .0038), although the loss variance was similar (P > .90). The mean presenting intraocular pressure (IOP) for patients with PXE (32.0 ± 5.2 mm Hg) was greater than that for patients with POAG (27.1 ± 4.4 mm Hg) (P= .0025). Additionally, patients with PXE required more treatment steps to control IOP (P = .005). Thirteen of 24 patients with PXE versus 3 of 22 patients with POAG (P = .016) required either laser or conventional surgical techniques to reduce IOP.

* CONCLUSION: This study shows that patients with PXE have greater visual field loss and have more difficulty gaining control of IOP on presentation than patients with POAG.

Tarsoconjunctival Advancement: A Modified Surgical Technique to Correct Cicatricial Entropion and Metaplasia of the Marginal Tarsus
Authors: Kuckelkorn Ralf , Schrage Norbert , Becker Jutta , Reim Martin
Published: April 2021

Abstract. Severe eye burns and mucocutaneous cicatricial disorders frequently cause upper and lower lid entropion with metaplasia of the tarsal conjunctiva, dislocation of the meibomian gland orifices, trichiasis, and tarsal scars near the lid margin. Between 1985 and 1993, 26 patients (29 eyes, 36 lids) were treated by excision of pathologic tissue and advancement of the tarsoconjunctival layer. The presented procedure is used mainly in cicatricial entropion with keratinization of the marginal tarsus. [Ophthalmic Surg Lasers 1997;28:156-161.]
Modified Needle Drainage of Subretinal Fluid for Conventional Scleral Buckling Procedures
Authors: Azad R V , Talwar Dinesh , Pai Anant
Published: April 2021

Abstract. This study evaluated the efficacy and safety of a new technique used to drain subretinal fluid (SRF) during conventional scierai buckling procedures. The procedure was performed on 15 patients with primary rhegmatogenous retinal detachment in whom drainage of SRF was necessary during the surgery. It was successful in all but 1 case. The only significant complication was subretinal hemorrhage from the punctured choroid in 1 case, which resolved spontaneously without subsequent complications. This technique reduced the risk of complications during external SRF drainage, especially retinal and vitreous incarceration. [Ophthalmic Surg Lasers 1997;28:165-167.]
Cosmetic Conformers
Authors: Patel Bhupendra C K , Sapp Nigel A , Collin J Richard O
Published: April 2021

Abstract. The loss of an eye is an emotionally traumatic event. A prosthetic eye is usually not fitted until the socket has healed (about 6 weeks after surgery). This period, during which a clear conformer is fitted, can be particularly traumatic, especially for the newly anophthalmic patient. The authors have designed interim acrylic prosthetic conformers to help patients overcome some of these problems while preserving the necessary characteristics of ideal postoperative conformers.

Positive Vitreous Cultures From Eyes Without Signs of Infectious Endophthalmitis
Authors: Mames Robert N , Friedman Scott M , Stinson William G , Margo Curtis E
Published: April 2021

* BACKGROUND AND OBJECTIVE: There is little information on the rate of false-positive vitreous cultures, because cultures from presumably sterile vitreous are not routinely taken in clinical practice. The objective of this study was to determine the rate of positive vitreous cultures from patients who have no signs of endophthalmitis.

* PATIENTS AND METHODS: Aerobic cultures from vitreous biopsies were taken from 36 consecutive eyes in which there was no clinical evidence of endophthalmitis. Effluent collected in cassettes during pars plana vitrectomies was processed and cultured in a standard manner. Balanced salt solution was processed intraoperatively through the vitrector and cultured as a negative control.

* RESULTS: Positive cultures were obtained in 8 of 36 eyes (22.2%). Coagulase-negative Staphylococcus and Corynebacteria accounted for 7 of the 9 identified organisms. No organism was grown in more than one medium. None of the patients were treated for endophthalmitis after surgery, and none had signs of intraocular infection.

* CONCLUSIONS: A substantial number of vitrectomy cultures from effluent specimens grow low-virulence organisms in the absence of clinical signs of endophthalmitis. The absence of inflammation at the time of surgery suggests that these positive cultures are contaminants.

Cornea and Iris Changes in Congenital Ectropion Uvea After Trabeculotomy
Authors: Khorram K David , Mets Marilyn B
Published: April 2021

Abstract. This article details a previously undescribed complication of trabeculotomy occurring in a patient with congenital ectropion uvea and discusses its possible association with an anterior chamber membrane. A 6-year-old boy with congenital ectropion uvea underwent trabeculotomy. After the trabeculotome was swept into the anterior chamber, multiple ovoid and round endothelial and posterior stromal opacities developed in the cornea, and new areas of iris surface irregularities appeared. This is the first reported case of corneal endothelial and iris changes occurring in a patient with congenital ectropion uvea after trabeculotomy without direct endothelial or iris contact from the trabeculotome. The exact cause of these changes is unknown. [Ophthalmic Surg Lasers 1997;28:418-421.]

Abstract. The authors describe a patient with a penetrating ocular injury from a metal wedge, a common hand tool used by road service technicians for the purpose of opening a locked car door. The patient had a penetrating eye injury from a metal wedge when its sharp end released from a car door lock and retracted upward, striking the right eye. No report exists of ocular injury using a metal wedge for its intended purpose of opening a car door lock. The use of polycarbonate lenses might afford some protection.

The Continuous-injection Technique to Reduce Complications During Retrobulbar Anesthesia
Authors: Kuhn Ferenc , Mester Viktoria , Berta Andras
Published: April 2021

Abstract. Retrobulbar as well as peribulbar anesthesia remain relatively risky procedures; retrobulbar hemorrhage and especially globe penetration or perforation can have blinding consequences. Our continuous-injection-technique greatly reduces these risks whether used for retrobulbar or peribulbar anesthesia. If the ophthalmologist starts injecting the agent while advancing the needle, the fluid pushes tissues away, possibly preventing a hemorrhage. Since resistance against the plunger is instantaneously experienced if the needle impacts the sclera, the ophthalmologist is adequately warned before actual perforation of the sclera occurs.

The Treatment of Punctal and Canalicular Stenosis in Patients on Systemic 5-FU
Authors: Fezza John P , Wesley Ralph E , Klippenstein Kimberly A
Published: April 2021

* PURPOSE: 5-FU administered systemically for cancer treatment can cause punctal and canalicular stenosis leading to symptoms of tearing. While some patients receiving 5-FU have resolution of their tearing with cessation of the drug, many patients require surgical treatment of their lacrimal outflow system. We studied the severity of punctal and canalicular stenosis in patients on 5-FU and the various treatments required to correct symptoms of tearing.

* METHODS: Nineteen patients (16 with colon cancer and 3 with breast cancer) who were treated with systemic 5-FU with complaints of tearing were studied retrospectively. Treatment modalities were based on punctal stenosis evaluated by slit lamp exam, and probing and irrigation of the lacrimal outflow system.

* RESULTS: All patients demonstrated bilateral punctal and canalicular stenosis on exam. Fifteen of the 19 patients underwent surgery with 4 declining any surgical intervention. Of those 15 patients who underwent surgery; 5 had bilateral silicone tube intubation, 3 had bilateral conjunctivodacryocystorhinostomies (CDCR), 1 had a silicone tube on one side and a CDCR on the other side, 1 had a bilateral DCR, 4 had bilateral punctal 3-snip procedures, and 1 failed bilateral silicone tube intubation and will require bilateral CDCR.

* CONCLUSION: This is the Jargest single study in the literature evaluating patients on systemic 5-FU for the sequela and treatment of tearing. Although we found varying degrees of punctal and canalicular stenosis among our 19 patients, almost all had stenosis severe enough to warrant surgical intervention with either silicone tubes or CDCR. In our study 4 of 15 patients who elected surgery (26.7 %) required CDCR, because of the permanent, severe stenosis of the lacrimal outflow system. Physicians should be aware that early recognition and treatment of tearing in patients on 5-FU with silicone tubes may salvage the canalicular system and prevent the need for CDCR.

Published: April 2021

Abstract: To determine carotid cavernous fistula associated with choroidal detachment after cataract surgery. A 77-year-old woman underwent cataract surgery in both eyes. Postoperatively, proptosis and dilation of episcleral vessels in her left eye occurred and gradually increased. One month later, choroidal detachment developed in her left eye. Computed tomography showed an enlarged superior ophthalmic vein. Selected cerebral angiography showed fistulas between the megingeal branches of both the internal and external carotid arteries and the cavernous sinus. After the neurosurgical treatment, these symptoms disappeared. The development of carotid cavernous fistula after cataract surgery, as demonstrated in our patient, may be uncommon.

Using the Second Instrument Peripheral Corneal Incision in Phacoemulsification as a Blow-Off Valve
Authors: Rauz Saaeha , Jacks Andrew S , Govan James A A
Published: April 2021

* PURPOSE: To assess the rise in intraocular pressure following phacoemulsification and whether it can be modified by the architecture of the peripheral corneal incision for the second instrument.

* SETTING: Frimley Park Hospital, Frimley, United Kingdom.

* METHOD: Forty-two patients had intraocular pressures measured from both eyes preoperatively, then underwent routine scleral section phacoemulsification. They were randomly assigned to perpendicular (blow-off valve) and oblique (water-tight) peripheral corneal incision groups. Postoperative intraocular pressures were measured at 3, 6, 12 and 18 hours. Pressures from the unoperated eyes were used as controls. Aqueous release from the second instrument peripheral corneal incisions and frown scleral incision were assessed using the Seidel's test.

RESULTS: There was a rise in intraocular pressure in both groups compared to the control eyes (mean 10.95±2.19mmHg, P<0.00005) at 6 hours. The difference between the groups was significant at 12 hours (mean difference 3.35 mmHg, P<0.05); 63.6% of the perpendicular incisions and 15% of the oblique incisions were Seidels positive. The frown incision did not leak.

* CONCLUSION: This study documents the natural history of the rise in intraocular pressure following phacoemulsification peaking at 6 hours. Pharmacological agents should be administered to cover this period. The perpendicular peripheral corneal incision had a tendency to act as a blow-off valve allowing release of aqueous when intraocular pressures were elevated in the first 18 hours following phacoemulsification. This phenomenon is likely to result in a reduction in rise of intraocular pressure compared to the oblique peripheral corneal incision group which tended to be water-tight.

Abstract. To report a case of mucinous adenocarcinoma of the eyelid. A 70-year-old man presented with a lesion of his lower left eyelid, which had been growing over the past few years. An excisional biopsy was performed. The lesion was incompletely excised and recurrence at the excision site was observed at a 3-month follow-up visit. A histopathological examination of the excised specimen showed it to be a mucinous adenocarcinoma of eccrine origin. Primary mucinous adenocarcinoma of the eye lid is a rare malignant sweat gland tumor with a high incidence of local recurrence. It has to be differentiated from other adenocarcinomas which may rarely metastasize to the skin. [Ophthalmic Surg Lasers 1999;30:394-395.
Pneumatic Buckle for the Repair of Primary Rhegmatogenous Retinal Detachment
Authors: Purohit Surendar S , Matthews G Philip , Zakov Z Nicholas
Published: April 2021

* OBJECTIVES: This prospective study examines the effectiveness of the pneumatic buckle procedure (nondrainage scleral buckle with pneumatic retinopexy) for repair of primary rhegmatogenous retinal detachments.

* METHODS: We studied 58 consecutive patients with primary rhegmatogenous retinal detachments who underwent a pneumatic buckle with air or SF6. The procedures were performed at 2 centers. Retinal reattachment and visual acuity were examined.

* RESULTS: The single operation reattachment rate for patients undergoing a pneumatic buckle procedure was 95%. Eighty eight percent of patients with macula-on detachment had unchanged or improved final visual acuity. Sixty seven percent of patients with macula-off detachments had a final visual acuity between 20/20 and 20/50. Twenty nine percent had final visual acuity between 20/60 and 20/200. Two patients developed a new retinal hole postoperatively.

* CONCLUSION: Pneumatic buckle is an effective technique for repair of primary rhegmatogenous retinal detachments caused by breaks in the superior 8 o'clock segment. This technique avoids the complications associated with the drainage portion of the traditional scleral buckle operation and results in a high rate of retinal reattachment and stable or improved visual acuity. The rate of new retinal hole formation in this study is much lower than those reported for pneumatic retinopexy.

Published: April 2021

* OBJECTIVE: To determine the relationship between eye drop use and contamination rate in ophthalmology offices.

* DESIGN: Following permission request, open bottles were examined and the nozzle tip and one drop of content was cultured on solid media.

* OUTCOME MEASURES: Drug category, volume, weight compared to full, clean legible label, expiration date; 2 or more bacterial colonies along the inoculation site.

* RESULTS: In 18 offices, of 1,485 open bottles (mean 12.2, range 4 to 23 per lane) on average 19.8% (range 0% to 88%) were expired (16.2 of 82.5 bottles per office). The frequency of occurrence (%) and expiration (%E) were 40.3% cycloplegics (19.4%E); 16.4% glaucoma (33.7%E); 10.8% anesthetics (8.8%E); and 4% steroids (8.8%E; or 42.2%E including one outlier). Most likely expired were glaucoma (P < 0.001); small 2-3 ml (P < 0.02), nearly empty (P < 0.05), or dirty (P < 0.001) bottles. Only one (5 ml cyclopentolate, not expired) grew a Micrococcus (0.07%).

* CONCLUSIONS: Drops in ophthalmology offices may be expired but are not contaminated.

Published: April 2021

Abstract. A technique for incising thick retrolental fibrovascular tissue and extensive cyclitic membrane is reponed in a case of anterior persistent hyperplastic primary vitreous. A membranectomy was performed in a 1-month-old post-lensectomy baby via a limbal approach. A sclerotome tip was hooked to cut through an extremely thick fibrovascular tissue by rotating the sclerotome by its grip. Sutherland microscissors (Grieshaber, Switzerland) and a vitrectomy cutter were used for further membranectomy. The baby was followed-up until age 18 months. A total of 3 membranectomy sessions were required because of rapid cyclitic membrane formation, severe centripetal retraction of the membrane on the ciliary processes, and posterior synechia. Thorough membranectomy and cutting the iris edge maintained a clear pupillary area during the 13-month postoperative period. Extremely thick retrolental fibrovascular tissue is a challenging condition that can be dealt with by delicate instrumentation. [Ophthalmic Surg Lasers 1999;30:758-761.]
A Comparison of Your Better Life Index and Its Antecedents Across Two Chinese Cultures
Authors: Gao Jennifer H.
Published: April 2021

OECD identified 11 topics in Your Better Life Index (YBLI). YBLI is generally accepted as an essential indicator of material living conditions and quality of life. This study compared YBLI in two predominantly Chinese regions, i.e., Macau (a former Portuguese territory in China) and Zhuhai in the Greater Bay Area in the southern part of the People’s Republic of China. Data were collected from 446 (231 Macau and 215 Zhuhai) ethnic Chinese residents in the two regions. Results revealed the Macau residents to be much more satisfied with life (significantly higher ratings on more YBLI topics) than their Zhuhai counterparts. Regression analyses revealed Chinese Values and Family Emotional Support to be strong predictors of YBLI in Zhuhai, while Future Prospects and Self-Efficacy explained most variance for YBLI in Macau. The results of the comparisons are discussed in terms of seminaries and differences in the cultures and economic development of the regions.

After concussion, a multifaceted assessment is recommended, including tests of physical exertion. The current criterion standard for exercise testing after concussion is the Buffalo Concussion Treadmill Test (BCTT); however, validated tests that use alternative exercise modalities are lacking.

Objective

To evaluate the feasibility and concurrent validity of a universal cycling test of exertion compared with the BCTT in adults who sustained a sport-related concussion.

Design

Crossover study.

Setting

University sports medicine clinic.

Patients or Other Participants

Twenty adults (age = 18–60 years) diagnosed with a sport-related concussion.

Intervention(s)

Participants completed the BCTT and a cycling test of exertion in random order, approximately 48 hours apart.

Main Outcome Measure(s)

The primary outcome of interest was maximum heart rate (HRmax; beats per minute [bpm]). Secondary outcomes of interest were the total number of symptoms endorsed on the Post-Concussion Symptom Scale, whether the participant reached volitional fatigue (yes or no), the symptom responsible for test cessation (Post-Concussion Symptom Scale), maximum rating of perceived exertion, symptom severity on a visual scale (0–10), and the time to test cessation.

Results

Of the 20 participants, 19 (10 males, 9 females) completed both tests. One participant did not return for the second test and was excluded from the analysis. No adverse events were reported. The median HRmax for the BCTT (171 bpm; interquartile range = 139–184 bpm) was not different from the median HRmax for the cycle (173 bpm; interquartile range = 160–182 bpm; z = −0.63; P = .53). For both tests, the 3 most frequently reported symptoms responsible for test cessation were headache, dizziness, and pressure in the head. Of interest, most participants (64%) reported a different symptom responsible for cessation of each test.

Conclusions

On the novel cycling test of exertion, participants achieved similar HRmax and test durations and, therefore, this test may be a suitable alternative to the BCTT. Future research to understand the physiological reason for the heterogeneity in symptoms responsible for test cessation is warranted.

Chaotic resonant dynamics and exchanges of energy in Hamiltonian PDEs
Authors: Giuliani Filippo , Guardia Marcel , Martin Pau , Pasquali Stefano
Published: April 2021

The aim of this note is to present the recent results in [16] where we provide the existence of solutions of some nonlinear resonant PDEs on T2 exchanging energy among Fourier modes in a "chaotic-like" way. We say that a transition of energy is "chaotic-like" if either the choice of activated modes or the time spent in each transfer can be chosen randomly. We consider the nonlinear cubic Wave, the Hartree and the nonlinear cubic Beam equations. The key point of the construction of the special solutions is the existence of heteroclinic connections between invariant objects and the construction of symbolic dynamics (a Smale horseshoe) for the Birkhoff Normal Form of those equations.

The purpose of this study is to analyze policies on the prevention and handling of forest and land fires in Central Kalimantan Province and analyze the factors that influence the prevention and handling of forest and land fires in Central Kalimantan Province. The study used qualitative research methods, with research informants consisting of the Governor, the Head of the Forest Service, the Head of the Environmental Service, Community Leaders, and the people of Central Kalimantan Province. The data collection technique is done by observation, interview, and documentation study. At the same time, the data analysis used is an interactive model analysis consisting of data condensation, data display, and drawing conclusions/verification. The results showed that in accordance with Regional Regulation No. 5 of 2003 and Governor's Regulation No. 24 of 2017, the policy of preventing and handling forest and land fires in Central Kalimantan Province was carried out in two stages, namely the prevention policy and the policy of handling forest and land fires. However, in its implementation, it prioritizes the policy to extinguish forest and land fires because it has more economic, social, educational, and health impacts. Efforts to prevent and handle forest and land fires in Central Kalimantan Province are constrained by inadequate human resources, limited budget, and lack of facilities and infrastructure.
