Extrusion of Enucleation Implants: Treatment With Secondary Implants and Autogenous Temporalis Fascia or Fascia Lata Patch Grafts
Authors: Wiggs Eugene O , Becker Bruce B 
Published: April 2021

ABSTRACT
We performed one autogenous fascia lata graft and 11 autogenous temporalis fascia grafts in eight patients with extrusion of an orbital enucleation implant and in four patients with a bulging implant who could not wear a prosthesis. Excluding one patient with inadequate follow up, 10 of the 11 patients (91%) successfully retained their implant. One patient had severe conjunctivitis followed by anterior migration of his implant 21/2 years after patch grafting, necessitating replacement of the implant. We conclude that autogenous temporalis fascia patch grafting is an effective treatment for orbital enucleation implant extrusion or a bulging implant.
Monopolar Cautery for Graft Cartilage Sculpting in Reconstructive Eyelid Surgery
Authors: Markowitz Gary D , Wulc Allan E , Perman Kevin I , Popp Jeffrey C 
Published: April 2021

ABSTRACT
We describe a technique for using the monopolar cautery to sculpt ear cartilage to prepare it for use as a graft to reconstruct or support the posterior lamella of the eyelid in oculoplastic procedures. We have used this simple, rapid, and predictable technique in 16 patients with excellent results.
A Modified Technique of Transscleral Suture Fixation of Posterior Chamber Lenses
Authors: Mittelviefhaus Hans 
Published: April 2021

ABSTRACT
I describe a modified technique of sulcus fixation of posterior chamber intraocular lenses (PC-IOLs) in which the anterior vitrectomy is restricted to the vitreous base and anterior chamber and a single-armed sling suture is used. These modifications reduce operating time and the risk of intraoperative and postoperative infection. This technique has been used successfully in the last 20 of the 96 patients in our institution who have had transscleral suture fixation procedures.
Intraocular Lens Implantation in an Almost Completely Retained Capsular Bag With a 4.5- to 5.0Millimeter Linear Dumbbell Opening in the Human Eye
Authors: Hara Tsutomu , Hara Takako 
Published: April 2021

ABSTRACT
As a preliminary step in developing a capsular opening that will permit the firm fixation of the full-size intraocular lenses (IOLs) of the future in a completely retained capsular bag, conventional 11-millimeter long posterior chamber IOLs with 6-millimeter polymethylmethacrylate optics were implanted in almost completely retained capsular bags with a 4.5- to 5.0-millimeter linear dumbbell opening. Undergoing the procedure were 23 cataractous eyes of 23 patients (average age, 72 ± 8 years). Average follow up was 15 ± 2 months. The dumbbell opening was made with an automated electric trephine or manually. The Cavitron 10 000 was used for phacoemulsification. Lens epithelial cell removal was performed by cryopexy. All IOLs were fixed in the capsule satisfactorily. Although complete transparency was not retained in any of the eyes, postoperative visual acuity was better than 10/20 in 16 eyes (70%). There were no apparent complications other than anterior capsular opacification.
Ciliary Sulcus Fixation of a Dislocated Posterior Chamber Intraocular Lens Using Liquid Perfluorophenanthrene
Authors: Fanous Maher M , Friedman Scott M 
Published: April 2021

ABSTRACT
A posterior chamber intraocular lens was transsclerally sutured to the ciliary sulcus with the aid of liquid perfluorophenanthrene (Vitreon®). This vitreous substitute facilitates the procedure and reduces the possibility of damage to the retina.
Using Donor Sclera to Create a Flap in Glaucoma Filtering Procedures
Authors: Riley Shawn F , Lima Francisco L , Smith Thomas J , Simmons Richard J 
Published: April 2021

ABSTRACT
We report a surgical technique in which donor sclera is used to create a flap in glaucoma filtering procedures. This simple technique is helpful when the sclera is too thin to safely and effectively form an adequate scieral flap. The use of donor sclera allows the procedure to continue as a guarded procedure and prevents early postoperative hypotony.
Proximity-Sensor Dimmer Device as an Aid in the Reduction of Operating Microscope-Induced Retinal Phototoxicity
Authors: Urinowski E , Cahane M , Ashkenazi I , Blumenthal M , Avni I 
Published: April 2021

ABSTRACT
The length of exposure to the light source of the operating microscope is a major factor determining retinal phototoxicity. In our experience, for about 20% of the time during cataract surgery, the surgeon is not looking through the oculars. To take advantage of these times, we designed a device, a proximity switch consisting of an infrared sensor mounted between the oculars in the operating microscope. When the surgeon's forehead approaches the microscope to look through the oculars, the sensor increases the illumination; when the surgeon moves away, it is automatically reduced. The resulting decreased overall exposure to light may reduce retinal phototoxicity.
A New Lens for Argon Laser Suture Lysis
Authors: Ritch Robert , Potash Seth D , Liebmann Jeffrey M 
Published: April 2021

ABSTRACT
Argon laser suture lysis is a valuable adjunct for regulating intraocular pressure and establishing a filtration bleb in the early postoperative period after trabeculectomy. We have developed a lens that provides excellent compression of the conjunctiva, an improved view of scleral flap sutures, and effortless retraction of the upper lid.
Lid Crease and Capsulopalpebral Fascia Repair in Congenital Entropion and Epiblepharon
Authors: Millman Arthur L , Mannor Geva E , Putterman Allen M 
Published: April 2021

ABSTRACT
Forty-one eyelids of 21 patients with congenital entropion or epiblepharon underwent transcutaneous reconstruction of the eyelid crease and retractor (capsulopalpebral fascia). All of the patients demonstrated lack of cutaneous-capsulopalpebral fascia attachment. In contrast with the patients with epiblepharon, those with congenital entropion also had partial or complete absence of tarsal-capsulopalpebral fascia attachment. Surgical treatment included anastomosis of the capsulopalpebral fascia, tarsal border, and eyelid skin crease; no skin or muscle was removed. With a minimum follow up of 1 year, malposition recurred in 3 of the 33 (9%) eyelids with epiblepharon, and in none of the 8 eyelids with entropion.
Penetrating Ocular Trauma in Children by "Broomstick Bows and Arrows"
Authors: Sharma Tarun , Agarwal Premlata , Gopal Lingam , Badrinath Sengamedu Srinivasa , Murugesan Radha 
Published: April 2021

ABSTRACT
Ocular trauma by "broomstick bows and arrows" is a unique penetrating injury among Indian children. Hitting the eye with a great velocity, these highly contaminated missiles may cause severe damage. The results of surgical treatment of 100 children who suffered such trauma are presented. Anatomic success, ie, successful reconstruction of the globe with attached retina, was attained in 85 (85%) of these eyes. Functional success, ie, improvement in visual acuity of two Snellen lines in eyes with measurable preoperative acuity, or improvement to at least 2/60 in the eyes with preoperative acuities of light perception or hand movements, was attained in 62 (62%) of the eyes. Of the functionally successful eyes, an acuity of 6/9 or better was achieved in 28 (45.2%). Factors predictive of poor anatomical success were:
* injuries involving both anterior and posterior segment (P<.02),
* endophthalmitis (P < .05), and
* presence of retinal detachment with or without proliferative vitreoretinopathy (P <.05).
Mean follow up was 4.5 ± 3.59 months (range, 2 to 24 months).
Hyperplastic Pupillary Membrane and Laser Therapy
Authors: Kumar Harsh , Sakhuja Navin , Sachdev Mahipal S 
Published: April 2021

ABSTRACT
The eyes in two cases of extensive hyperplastic pupillary membranes with significant reduction of visual acuity and clarity were subjected to sectioning of the membranes in the superior 270° of the pupil using a Q-switched Nd:YAG laser. The complications of microhemorrhages, pigment dispersal, and elevation of intraocular pressure were insignificant, while the objective and subjective improvement in vision was remarkable.
Resident Phacoemulsification Experience Using the In Situ Nuclear Fracture Technique
Authors: Noecker Robert J , Allinson Richard W , Snyder Robert W 
Published: April 2021

ABSTRACT
We retrospectively reviewed all of the 176 phacoemulsification procedures attempted by two thirdyear residents from July 1, 1991 to June 30, 1992. The in situ nuclear fracture technique was performed in 131 eyes; a nonf radure technique in 45. Overall, the rate of vitreous loss was 4.5% (8 of 176). The rate of vitreous loss associated with the in situ nuclear fracture technique was 3.1% (4 of 135); with the nonfracture technique, 8.9%. We conclude that phacoemulsification can be learned and performed by residents with vitreous loss rates comparable to those reported for extracapsular cataract extraction.
Releasable "U" Suture for Trabeculectomy Surgery
Authors: Maberley David , Apel Andrew , Rootman David S 
Published: April 2021

ABSTRACT
Overfiltration after glaucoma surgery can lead to significant complications. Tight suturing of the trabeculectomy flap reduces this problem but can lead to higher pressure and poor drainage of aqueous. Releasable sutures often leave irritating exposed suture ends. We describe a simple two-arm releasable suture technique that leaves no exposed suture ends until one arm of the suture is removed. Good control of postoperative pressure with few complications was achieved in 28 cases using this technique, which allows manipulation at the slit lamp of the trabeculectomy flap, obviating laser lysis of the sutures.
Modifications of the Glaucoma Drainage Implant To Prevent Early Postoperative Hypertension and Hypotony: A Laboratory Study
Authors: Brooks Steven E , Dacey Mark P , Lee Martha B , Baerveldt George 
Published: April 2021

ABSTRACT
Hypotony or hypertension in the early postoperative period following implantation of a nonvalved seton such as the Molteno tube is a common problem. We conducted a laboratory investigation evaluating two modifications of the silicone drainage tube. One involved a longitudinally-oriented, pressure-sensitive slit-valve combined with an absorbable occluding ligature interposed between the valve and the episcleral plate. Experiments examining the relationship between slit length, opening pressure, and flow rate were performed. The second modification involves focally constricting the lumen of the tube with an external ligature in order to reduce flow rates. Our results indicate that a slit-valve length of 2.0 mm appears to provide a reliable opening pressure of around 10 mm Hg, with relatively high flow when pressures exceed opening pressure. Focally constricting the lumen of the tube, however, was shown to be both unpredictable and unsatisfactory for reducing the flow of fluid to a range consistent with steady state aqueous production.
The Efficacy of Cyclosporin-A in the Treatment of Behçet's Disease
Authors: Atmaca Leyla S , Batioglu Figen 
Published: April 2021

ABSTRACT
We used cyclosporin A (CA) to treat 14 patients (25 eyes) with Behçet's disease characterized by severe retinal vasculitis and active intraocular inflammation. All of the patients had been treated previously with corticosteroids, colchicine, and immunosuppressives, without satisfactory results. The patients were given an initial oral dose of 5 mg/kg/day. All medication was tapered and eventually completely stopped after 12 months. The number and severity of ocular attacks (anterior and/or posterior uveitis with vitreous haze) were significantly reduced below pretreatment levels during therapy (Kolmogorov Smirnov two-pair test: P < .05). Visual acuity improved in 32% and remained unchanged in 44%. No ocular attacks recurred in 11 eyes; they recurred 1 time in 8 eyes; 2 times in 3 eyes; and 3 times in 3 eyes during CA therapy. There were no significant changes in the level of retinal vasculitis. In two cases with vasoobstructive changes, treatment with CA was not effective and laser photocoagulation was performed.
Based on our study, we recommend that an initial dose of 5 mg/kg/day CA be used in the systemic medical treatment of ocular Behçet's disease. The CA can be continued at this low dosage for an unspecified time. If intraocular inflammation does not totally resolve at this dosage or the inflammatory process recurs, combining the CA with low doses of a steroid should be considered.
En Bloc Capsulectomy in the Diagnosis and Treatment of Refractory, Chronic, Recurrent Pseudophakic Endophthalmitis
Authors: Thach Allen B , Das Arup , Lopez Pedro F 
Published: April 2021

ABSTRACT
Anterior chamber and vitreous aspiration may fail to isolate a microorganism in chronic pseudophakic endophthalmitis. In some eyes, obtaining a portion of the central posterior lens capsule may assist in determining the infectious etiology of the endophthalmitis. We describe a technique by which the entire lens capsule and its internal contents are removed and cultured. This surgical method facilitated the isolation and eradication of the causative pathogen in a patient with chronic recurrent pseudophakic endophthalmitis that was diagnostically and therapeutical Iy refractory to previous vitrectomy, posterior capsutectomy, and intra vitrea! antibiotic injection.
Bubbles in the Bleb-Troubles in the Bleb? Molteno Implant and Intraocular Tamponade With Silicone Oil in an Aphakic Patient
Authors: Senn Peter , Büchi Ernst R , Daicker Basil , Schipper Isaak 
Published: April 2021

ABSTRACT
A 14-year-old aphakic girl who had had previous bilateral glaucoma surgery with a Molteno implant underwent pars plana vrtrectomy and silicone-oil tamponade for proliferati ve- vitreoretinopathy retinal detachment in both eyes. The filtering bleb of the left eye was functional for 5 months before becoming available for histologie examination. We found numerous foreign-body granulomas coating the inner surface of the bleb, as well as intracellular and extracellular deposits of emulsified silicone oil in the wall of the bleb. In the fellow eye, the filtering bleb remained functional despite repeated vitreous surgery with silicone oil. Filtration in aphakic eyes with previous Molteno surgery and silicone-oil tamponade after vrtrectomy may continue normally for a prolonged period of time, although emulsified oil droplets likely will have accumulated in the bleb and become incorporated in its fibrous capsule.

Published: April 2021

ABSTRACT
Inadvertent cyclodialysis cleft formation is a rare complication of intraocular surgery. We report a patient in whom a hypotonus cyclodialysis cleft developed following the removal of an anterior chamber intraocular lens. The cleft closed and the hypotony resolved after 1 month of topical atropine therapy.
Lamellar Keratoplasty Performed With a Corneal Scleral Button
Authors: Vrabec Michael P , Jordan Jeffrey J , Lawlor Peter P 
Published: April 2021

ABSTRACT
Tissue for lamellar corneal surgical procedures is usually harvested from whole eyes. We describe a surgical technique for the rehabilitation of corneoscleral defects with lamellar keratoplasty in which the donor tissue is obtained from a preserved corneoscleral button instead of a whole globe. This technique is illustrated with a case involving the treatment of a limbal der mo id in a 26-month-old boy.
Transscleral Repair of Recalcitrant, Inadvertent, Postoperative Cyclodialysis Cleft
Authors: Metrikin David C , Allinson Richard W , Snyder Robert W 
Published: April 2021

ABSTRACT
We present a patient with a cyclodialysis deft in whom, after established medical, laser, and initial surgical interventions had failed to close the cleft, we successfully used ab externo suture placement to appose and close it. Although we present only one case, we believe this procedure, which may be useful in pseudophakic and aphakic eyes, is easier to perform than previously described techniques.
Management of Retinal Detachment
Authors: Schepens Charles L 
Published: April 2021

ABSTRACT
I present what, in my opinion, is the optimal technique of managing primary simple retinal breaks and retinal detachment. For the preoperative examination, I recommend indirect stereoscopic ophthalmoscopy with scierai depression. The macula and suspected small peripheral breaks are studied with the biomicroscope and a three-mirror contact lens. Retinal breaks without retinal detachment are treated with cryotherapy if they are located anteriorly; with laser photocoagulation if they are posterior. Breaks with frank detachment can be treated with Lincoff's balloon, a procedure I prefer over pneumatic retinopexy. Multiple retinal breaks and those associated with fairly extensive chorioretinal degeneration are best treated with a permanent scierai buckling, the various modalities of which, along with their indications, I discuss in some detail.
Mitomycin C as Adjunctive Therapy With Glaucoma Implant Surgery
Authors: Susanna Remo , Nicolela Marcelo Teixeira , Takahashi Walter Y 
Published: April 2021

ABSTRACT
Twenty-one eyes of 21 patients with refractory glaucoma underwent glaucoma surgery involving placement of a modified Molteno implant and intraoperative application of mitomycin C. Sixteen eyes (76.2%) had an intraocular pressure (IOP) of 21 mm Hg or less after a mean follow up of 9.4 ± 6.4 months; additional medication was needed in six eyes. Major complications included early flat anterior chamber (42.9%), implant plate erosion (9.5%), tube erosion (4.8%), late hypotony (4.8%), tube-corneal touch (4.8%), and phthisis bulbi after choroidal hemorrhage (4.8%). Only one patient had a high IOP due to decreased filtration through the implant. These results suggest that glaucoma implant surgery with the adjunctive use of mitomycin C may be useful in eyes with refractory glaucoma.

Published: April 2021

ABSTRACT
Two cases involving retinal detachment caused by breaks in the pars plicata of the ciliary body are presented. In both, retinal detachment developed following surgery for atopic cataract. The residual lens capsules contracted with evidence of fibrotic change. Nonpigmented ciliary epithelium appeared to have become detached and torn by traction through the zonules of Zinn.
Suprachoroidal Hemorrhage in Penetrating Keratoplasty
Authors: Price Francis W , Whitson William E , Ahad Khandaker A , Tavakkoli Hassan 
Published: April 2021

ABSTRACT
Nine cases of intraoperative expulsive Suprachoroidal hemorrhage occurred in a series of 2011 consecutive penetrating keratoplasties (an incidence of 0.45%). In four cases, the complication was directly related to the anesthesia technique. The incidence of hemorrhage was 1.0% in the eyes with preoperative anterior chamber intraocular lenses (IOLs), an incidence significantly higher than for any other associated condition (P < .02). Four of the nine patients recovered a postoperative visual acuity of 20/70 or better We discuss reasons for the relatively high incidence of hemorrhage during penetrating keratoplasty; its occurrence in relation to the type of anesthesia used, prior intraocular surgery, types of surgery performed together with the penetrating keratoplasty,, and the presence of an anterior chamber IOL; and the risks introduced by hemorrhage in a fellow eye and by a previous hemorrhage in the same eye.
Calcein Fluorophotometry in Streptozocin-Induced Diabetic Rats
Authors: Golshani M Reza , Khoobehi Bahram , Peyman Gholam A , Aras Cengiz 
Published: April 2021

ABSTRACT
Calcein was used in vitreous flu oro photometry (VF) to study the blood-retinal barrier (BRB) in rats with streptozocin-induced diabetes. Calcein was injected intravenously in 18 diabetic rats and sodium fluorescein (NaF) in 12 diabetic rats. VF was performed at 1, 2, 4, 6, 9, and 21 hours following the single injection in these diabetic rats; it was also performed at these times in 24 normal (control) rats. On another day, the same experiment was performed using NaF. There was no significant difference between the two dyes in the diabetic and nondìabetic rats at 1 hour. However, at 4 hours and at later measurement points, there was dye leakage into the vitreous, peaking at 9 hours; the leakage was significantly greater in the diabetic rats. Also, the leakage was significantly greater with calcein than it was with NaF. The data demonstrate that calcein circulates longer and at higher levels than NaF and thus is probably more useful for BRB integrity studies.
Postoperative Intraocular Pressure Changes With Use of Different Viscoelastics
Authors: Dada Vijay K , Sindhu Narottama , Sachdev Mahipal S 
Published: April 2021

ABSTRACT
Sixty eyes with age-related cataract underwent extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens (PC-IOL) implantation under similar conditions using hydroxypropyl methylcellulose (HPMC) (Oculose) (n = 20), sodium hyaluronate (Healon) (n = 20), or hyaluronic acid (IAL) In = 20) as the viscoelastic (VE). Postoperative evaluation was performed for intraocular pressure OOP), corneal thickness, and anterior chamber reaction at 6, 24, 48, 72 hours, and 10 days. Statistically-significant rises in IOP with IAL and Healon were observed at 6 and 24 hours; no such rises were observed with Oculose (P < .05). Seven eyes in the IAL group and six in the Healon group had IOPs greater than 22 mm Hg at 6 hours (range: 22 to 38 mm Hg and 22 to 28 mm Hg, respectively). A significant increase in average corneal thickness was observed in all of the 60 patients at 6 hours (18.5%). The average thickness decreased to 6.8% by day 10, with no intergroup variations. There were significantly fewer anterior chamber cells at 6 hours in the Healon group. We conclude that all three viscoelastics are equally useful for routine ECCE with PC-IOL implantation. However, IAL and Healon do cause an early postoperative IOP increase, which, though transient, should be treated.
The Conjunctival Wart: Report of a Case and Review of Treatment Options
Authors: Miller Daniel M , Brodell Robert T , Levine Mark R 
Published: April 2021

ABSTRACT
Human papillomavirus, a papovavirus, is the causative agent of all warts. There are at least 63 subtypes of this virus, certain ones of which are more likely to cause warts in particular locations or to be associated with malignancies. Over the last 6 years, HPV-6, HPV-1 1, and HPV-16 have been detected in both benign and malignant lesions of the conjunctiva. We report a patient with a large viral papilloma of the palpebrai conjunctiva of the right lower eyelid. This case demonstrates that even very large viral papillomas can be treated successfully.
Pars Plana Fixation of Posterior Chamber Intraocular Lenses
Authors: Teichmann Klaus D 
Published: April 2021

ABSTRACT
Given the problems associated with iris-sutured and scleral-fixated intraocular lenses (IOLs), pars plana fixation might be a safer and more effective approach. Significant improvements in lens design and materials, and changes in surgical approach and technique may now make pars plana fixation an attractive alternative. As contrasted with Girard's technique (1981), the implant loops would not be incorporated (buried) into the scierai wall, nor would the IOL be inserted through the pars plana. Advantages of a pars plana fixation include the low risk of intraoperative and postoperative hemorrhage, and the chance of avoiding contact between the IOL, iris, and pars plicata, depending on the lens design. Only the nonpigmented inner layer of the pars plana would be in direct contact with the haptic of the IOL. Thus, pigment dispersion should not occur unless there is contact with the iris.
