Epigard in the Management of Eyelid Neoplasms
Authors: La Piana Francis G 
Published: April 2021

SUMMARY
Definitive repair of a surgical wound of the anterior lamella of an eyelid should be delayed in some cases until the surgeon is sure of the histopathologic diagnosis of the lesion and the adequacy of his resection. Epigard is a polyurethane-polypropylene barrier dressing that can be sutured to wound edges, protecting underlying tissues until definitive repair is undertaken. It is well tolerated, cosmetically acceptable, easily removed and does not impair definitive repair of the wound.
The Contact Lens Corneal Cutter: Accuracy and Reproducibility
Authors: Olson Randall J 
Published: April 2021

SUMMARY
The contact lens corneal cutter was used on ten freshly enucleated pig eyes in an attempt to determine its accuracy and reproducibility. We felt that a circular opening could be obtained; however, there was variability in the size of the tissue cut and a disparity between the internal and external openings, which was caused by the sharp angle of the cutting blade.
Surgical Management of Congenital Eyelid Coloboma
Authors: Patipa Michael , Wilkins Robert B , Guelzow Kurt W L 
Published: April 2021

SUMMARY
Congenital eyelid colobomas are a partial or total absence of eyelid structures. The degree of severity determines the surgical techniques employed for repairing the eyelid. We feel that early surgical treatment reduces the risk of ocular scarring with satisfactory results.
We present four cases of congenital upper eyelid colobomas of differing severity and discuss surgical approaches to these lid abnormalities.
Evaluation of Sources of Variation on the Accuracy and Reproducibility of Microkeratome Sections with the Modified Artificial Anterior Chamber
Authors: Maguen Ezra , Azen Stanley P , Pinhas Simon , Villaseñor Richard A , Nesburn Anthony B 
Published: April 2021

SUMMARY
A study was carried out to evaluate effects of various sources of variation on the accuracy and reproducibility of the modified artificial anterior chamber in obtaining lamellar sections from rabbit cornea. Sources of variation included a) measurement error, inter-cornea and inter-session variation, b) length of storage time in M-K medium, and c) choice of preselected values of thickness and diameter. The findings indicated that a) measurement error, inter-cornea, and inter-session variations were of nominal magnitude; b) the length of storage time up to 10 days did not affect the precision of the procedure; c) the precision of diameter determinations did not depend on the preselected value of the diameter; d) the precision of thickness determinations did depend on preselected parameter values; and e) parameter values tended to be underestimated, Regression equations therefore are provided to adjust for the underestimation of thickness and diameter. Based on these findings, it was concluded that the modified artificial anterior chamber is adequate for use in experimental refractive keratoplasty since it provides adequate diameter values and is reproducible.
Malignant Glaucoma Following Cataract Extraction and Intraocular Lens Implant
Authors: Hanish Sidney J , Lamberg Robert L , Gordon James M 
Published: April 2021

SUMMARY
A 72-year-old woman developed malignant glaucoma following a routine intracapsular cataract extraction with intraocular lens insertion. The eye was not previously glaucomatous, nor was the anterior chamber angle previously shallow.
Pigment in Cellular Membranes on Intraocular Lens Implants
Authors: Wolter J Reimer 
Published: April 2021

SUMMARY
Cells with protoplasmic pigment granules on the surface of intraocular lens implants can be divided by their basic nature into histiocytes, epithelioid cells, giant cells, small fibroblast-like cells, iris melanocytes, pigment epithelium, and probably corneal endothelium. All these cells are part of a cellular membranes that have been observed on lens implants at times between eight months and three and a half years after lens implantation.
Long-Term Study of Iris Sutures in Rabbits
Authors: Allen Molly V , Jones Ed , Snow Ronald , Peiffer Robert L 
Published: April 2021

SUMMARY
A review of the literature of iris suture studies in rabbits, monkeys, and man reveals that all studies have been limited to six months or less. This project addresses the longevity of 10-0 prolene as an iris suture in vivo in the rabbit over a two-year period. Light and scanning electron microscopy examination demonstrated 10-0 prolene as relatively non-degradable and inert.
An Unusual Intranasal Anomaly of the Lacrimal Drainage System
Authors: Raflo Gary T , Horton Joseph A , Sprinkle Philip M 
Published: April 2021

SUMMARY
A newborn infant presented with a mass in the medial canthal area. Radiologic evaluation demonstrated this to be an abnormality in the nasolacrimal system. Examination of the nose showed a large cystic structure totally occluding the right naris. Surgical excision of the entire cyst was required to alleviate the patient's recurrent mucoceles of the lacrimal sac and epiphora. The need for nasal examination and more thorough evaluation in cases of recurrent obstruction is emphasized in evaluating patients with congenital obstruction of the nasolacrimal drainage system.
Central Cornea Involvement in Terrien's Degeneration
Authors: Nirankari Verinder S , Kelman Shalom E , Richards Richard D 
Published: April 2021

SUMMARY
A 15-year-old female showed classical signs of Terrien's corneal degeneration including peripheral corneal thinning, vascularization, lipid deposition, and ectasia. She also showed episodes of conjunctival inflammation and perforation following minor trauma, all in the presence of an intact epithelium. She also showed progressive central corneal thinning and opacification, features not reported in the literature in the last 30 years.
Complications of the Simcoe Flexible Loop Phacoprosthesis in the Anterior Chamber
Authors: Girard Louis J , Madero Roberto , Monasterio Remberto 
Published: April 2021

SUMMARY
A preliminary study of the use of a Simcoe 101-J implant in the anterior chamber after pars plana lensectomy by ultrasonic fragmentation showed initially good results. Further observations of these and additional eyes showed 20/20-20/40 vision in 86.9%, retinal detachment in 3.5%, retinal hole in 1.5%, clinical cystoid maculopathy in 13%, and socalled UGH syndrome in 5%.
Pars plana lensectomy alone in the last 136 eyes resulted in vision of 20/20-20/40 in 98.5%; a retinal detachment rate of 0.73%, retinal hole rate of 0.73%, no UGH syndrome, and no clinical cystoid maculopathy. Pars plana lensectomy alone appears to be a far safer procedure than pars plana lensectomy plus a Simcoe implant in the anterior chamber.
Implantation of the Simcoe 101-J manufactured by IOLAB Corp. in the anterior chamber is not recommended.
Correction of Postkeratoplasty Astigmatism by Razor Blade and V-Shaped Knife Wedge Resection
Authors: van Rij G , Vijfvinkel G 
Published: April 2021

SUMMARY
Improvement in microsurgical techniques and tissue storage has resulted in a higher rate of clear grafts after penetrating keratoplasty. The postoperative astigmatism however still remains a major problem. If a high corneal astigmatism cannot be managed successfully with glasses or contact lenses, a surgical approach may be indicated. We developed a V-shaped knife which makes a crescentic wedge resection easier to perform. Before the introduction of the V-shaped knife we obtained an average reduction in corneal astigmatism of 6.6 diopters. With the V-shaped knife the reduction was 8.0 diopters.
We think that the V-shaped knife makes a wedge resection easier and safer.
Late Ocular Hypotony Following Intracapsular Cataract Extraction: Probable Relation to Premature Resorption of Polyglactin 910 Sutures
Authors: Sanitato James J , Sacks Joel G 
Published: April 2021

SUMMARY
We have recently had a series of seven patients who developed late ocular hypotony, flat anterior chambers, and choroidal detachments following cataract surgery. In each case, there was evidence of premature dissolution of the polyglactin 910 sutures that were used for closure. From this experience we propose steps that can be taken to minimize such problems.
Experimental Evaluation of a Posterior Drainage System
Authors: Haas Joseph S , Peyman Gholam A , Lim Jin 
Published: April 2021

SUMMARY
We have evaluated an experimental artificial shunt to drain intraocular fluid into the retrobulbar space. The device consists of a hollow needle for insertion into the eye, a slit valve to regulate the drainage pressure, and a dome-shaped outflow system. The device was inserted through the sclera, choroid, and retina into the eyes of cynomolgus monkeys. The system was tolerated without producing retinal detachment. A localized foreign body reaction occurred in the retina, choroid, and sclera adjacent to the device. The intraocular pressure was lowered until fibrous encapsulation of the outflow system occurred.
Simulated Blowout Fracture of the Orbit
Authors: Brinkley James R , Acomb Thomas 
Published: April 2021

SUMMARY
A case of probable traumatic simulated Brown's syndrome, in which there was a false positive orbital tomogram, is presented. To our knowledge, this combination of findings has not been previously reported. The deceptive clinical signs combined with the false positive radiologic data led to the erroneous diagnosis of blowout fracture of the orbital floor and to a subsequent negative surgical exploration. Surgeons should be aware that these two infrequent findings may occur together. When there is any doubt about the diagnosis of blowout fracture of the orbital floor with muscle entrapment, conservative management may be indicated.
Vacuum Trephination of the Hypotonous Eye
Authors: Phillips Robert L 
Published: April 2021

SUMMARY
Removal of the recipient cornea in therapeutic keratoplasties is made more difficult by the hypotonous eye. A deep and symmetrical cut can be obtained by use of the vacuum trephine without unduly endangering the iris or lens. This technique may be preferred to other more time-consuming methods of pre-pressurizing the eye, and allows a better removal of the recipient cornea than with scissors removal following an epithelial mark.
A Retained Retrobulbar Catheter for Repetitive Injection of Anesthetics During Ophthalmic Surgery
Authors: Tamai Makoto 
Published: April 2021

SUMMARY
For extending the period of retrobulbar anesthesia, an Angiocath was retrobulbarly retained for repetitive delivery of local anesthetics. The retrobulbar placement of the cannula made possible easy and safe addition of local anesthetics by any time, amount and frequency.
A Useful Alternative to Silicone Intubation in Congenital Nasolacrimal Duct Obstructions
Authors: Havins Weldon E , Wilkins Robert B 
Published: April 2021

SUMMARY
Initial treatment of congenital nasolacrimal duct obstructions, by a variety of methods, is highly successful. However, a small percentage of obstructions either are not cleared or recur. Silicone intubation has been reported highly successful in treatment of these obstructions. This paper describes our experience with infracturing the inferior turbinate (described originally by Jones and Wobig) as being at least as highly successful, safe, and easy to perform.
Penetrating Ocular Injury Caused by Nylon Cord Fragment From Electric Lawn Trimmer
Authors: Barr Charles C , Mitchell Dean 
Published: April 2021

SUMMARY
A 58-year-old man sustained a penetrating injury in the left eye from a nylon cord fragment from an electric rotary weed trimmer. Repair of the corneal laceration, foreign body extraction, and anterior vitrectomy were performed. One year post injury the visual acuity was stable at 6/60. The need for protective eyewear when using power tools is emphasized.
"Silicone-Octopus Repair" of Lacrimal Obstructions in Children
Authors: Nagashima Koji 
Published: April 2021

SUMMARY
Nineteen pediatric cases of lacrimal obstruction due to acquired disorders were repaired by a modification of the conventional silicone intubation procedure. This new operation employs an increased number of silicone strands within the lower excretory system. Sixteen patients had very good results and two were improved; there was one failure. This procedure is indicated in children with combined common canalicular and nasolacrimal duct obstruction.
Vitreoretinal Changes Associated With Rise in Intraocular Pressure After Nd:YAG Capsulotomy
Authors: Schubert Hermann D 
Published: April 2021

ABSTRACT
In a chart review of 100 consecutive Nd:YAG laser capsulotomies, six presumed risk factors of the rise in intraocular pressure (IOP) after capsulotomy were identified. A group of 15 patients in which the pressure rose to at least 10 mmHg above baseline postoperatively showed a significant (P ≤ 0.01) association with myopia, vitreoretinal disease, and vitreous prolapse into the anterior chamber. The previously known association of high pressures with glaucoma, a large capsular opening, or absence of a posterior chamber lens were also confirmed. There was no correlation between the energy used and IOP.
These retrospective findings are suggestively consistent with the concept that injury to a liquefied vitreous may contribute to the IOP rise after capsulotomy.
Overcoming Difficulties in Trephining Donor Corneas for Penetrating Keratoplasty
Authors: Alfonso Eduardo 
Published: April 2021

ABSTRACT
The complication of the donor button becoming trapped inside the barrel of the trephine blade can become a frustrating situation for the surgeon who is trying to recover it. The use of a sterile medicine dropper to apply slight suction to the epithelial side of the button allows for easy and secure removal of the trapped button without the risk of distortion or direct trauma to the endothelium as could occur with other methods.
Autogenous Dermis-Fat "Baseball" Orbital Implant
Authors: Bullock John D 
Published: April 2021

ABSTRACT
A new procedure has been devised for the construction of an autogenous dermis-fat orbital implant, in which two figure-eight-shaped dermis-fat grafts are sutured together into a baseball shape. Correct implant size can be determined by preplacement of different-sized Mule spheres and testing for accurate fit. The "baseball" implant eliminates deep orbital fat which is distant from a vascular supply, and because it is covered with dermis, it maximizes graft vascularization, thus promoting survival of the implanted tissues. In eight patients, followed postoperatively for as long as 28 months, baseball implants have produced highly satisfactory results.
Orbital Cellulitis Following Strabismus Surgery
Authors: Wilson M Edward , Paul T Otis 
Published: April 2021

ABSTRACT
Orbital cellulitis is a rare complication of extraocular muscle surgery. Two cases have been reported since 1935. No report of this sight-threatening and life-threatening complication of strabismus surgery has appeared since computerized tomography became readily available. The following is a report of a case of orbital cellulitis occurring unilaterally following bilateral strabismus surgery in which computerized tomography was helpful in verfication and management. Early antibiotics resulted in a favorable outcome. The case is compared to those reported by von Noorden.
Orbital Histiocytic Lymphoma Arising From the Ethmoid Sinus
Authors: Cheij George , Cooper John L , Wesley Ralph E 
Published: April 2021

ABSTRACT
Histiocytic lymphoma has been reported previously as an orbital manifestation of systemic malignancy. We report herein a 49-year-old white male with orbital involvement from a sclerosing lesion in the ethmoid sinus that initially caused a biopsy-proven orbital inflammatory mass. This report of an orbito-sinus histiocytic lymphoma underscores the need to re-biopsy symptomatic orbital inflammatory lesions that continue to enlarge.

Authors: Katowitz James A , Kropp Thomas M 
Published: April 2021

ABSTRACT
A case of dacryocystitis due to Mycobacterium fortuitum is reported with secondary chronic granulomatous abscess of the eyelid. Mycobacterium fortuitum is an atypical Mycobacterium rarely encountered in ophthalmic practice. The clinical course of the abscess caused by Mycobacterium is reviewed and the successful management of this problem by cryotherapy discussed.
Argon Laser Treatment of Periocular Lesions: An Experimental Study
Authors: Summers C Gail , Hordinsky Maria D 
Published: April 2021

ABSTRACT
Argon laser photocoagulation is a promising alternative in the treatment of vascular lesions of the lid and periocular tissues. Experimental argon laser treatment of feline ocular and oral mucosa was undertaken to identify a protective shield that was satisfactory in preventing ocular damage and to identify a power that would be effective but avoid significant side effects.
Modified "Double-Z-Plasty" in the Closure of Medial Canthal Defects
Authors: Harvey John 
Published: April 2021

ABSTRACT
The correction of medial canthal defects following tumor resection is a very common problem in oculoplastic surgery, and consequently, many surgical techniques have been devised to accomplish this. Limberg's "rhomboid flap" is a technique which has been modified especially to suit the particular anatomy of the medial canthus. This technique embodies mobilization of thin eyelid skin as opposed to thicker nose, brow, or facial skin. A representative case is presented.
Complications of Subconjunctival 5-Fluorouracil Following Glaucoma Filtering Surgery
Authors: Lee David A , Hersh Peter , Kersten Diane , Melamed Shlomo 
Published: April 2021

ABSTRACT
The antimetabolite 5-fluorouracil (5-FU) has been used to inhibit fibroblastic growth to increase the success rate in glaucoma nitration surgery. Subconjunctival 5-FU can have adverse side effects. This paper describes two cases in detail of the ocular side effects of 5-FU. The first case is representative of the ocular surface problems. The second case deals with bleb leaks. Relative contraindications to 5-FU treatment are pre-existing ocular surface problems, early postoperative bleb leaks and fornlx-based conjunctiva! flaps in filtering procedures. New drug delivery methods are presently being investigated to help decrease the adverse side effects and increase the efficacy of 5-FU.
Antibiotic Resistance of Crystalline Bacterial Ingrowth in a Corneal Graft
Authors: Kincaid Marilyn C , Snip Robert C 
Published: April 2021

ABSTRACT
Four recent reports have described the clinical appearance of fine needle-like opacities in the corneal stroma of six patients. In five of these patients these developed in a corneal graft. Histologically, all the corneal buttons had bacterial ingrowth between the stromal lamellae, with a striking lack of inflammatory response. We report a patient in whom this process occurred following penetrating keratoplasty. Intensive topical antibiotic treatment failed, and she underwent a second, successful, penetrating keratoplasty. Postoperatively, this patient has maintained good vision with no recurrence for over three years. Histologic and ultrastructural study of the corneal button revealed viable and nonviable gram-positive cocci with a marked paucity of inflammatory infiltrate.
Giant Cysts of the Conjunctiva Following Scleral Buckling
Authors: Newton James C , Pruett Ronald C , Merhige Kenneth E , Maris Peter J 
Published: April 2021

ABSTRACT
Four patients developed giant conjunctiva! cysts following scierai buckling for retinal detachment. Histologically these cysts showed a core of fibrous tissue lined by stratified, non-keratinizing epithelium and with goblet cells. They probably arose from inadvertent implantation of epithelium during surgery. In three cases the cysts were surgically excised without recurrence. Alternate modes of therapy are discussed.
Review of Choroidal Osteoma: Successful Krypton Red Laser Photocoagulation of an Associated Subretinal Neovascular Membrane Involving the Fovea
Authors: Morrison Debra L , Magargal Larry E , Ehrlich Dion R , Goldberg Richard E , Robb-Doyle Eileen 
Published: April 2021

ABSTRACT
Laser treatment of a subretinal neovascular membrane associated with a unilateral choroidal osteoma in a 28-year-old woman is described. To our knowledge, this is the first reported use of krypton red laser photocoagulation for the initial treatment of a subfoveal neovascular membrane in this setting. Early recognition of the membrane allowed treatment prior to involvement of the central fovea. Follow-up has shown obliteration of the membrane without recurrence and 20/20 vision. We emphasize recognition of this unusual tumor, self-monitoring with an Amsler grid, and early treatment of subretinal neovascularization in this high risk group of young patients.
Pseudophakic Keratoplasty: Posterior Chamber Lens Implantation in the Presence of Ruptured Capsule
Authors: Smith Ronald E , Beatty Richard F , Clifford William S 
Published: April 2021

ABSTRACT
A technique is described for implantation of a posterior chamber intraocular lens during keratoplasty for bullous keratopathy when a large capsulotomy and vitreous prolapse are present. Seven cases of Pseudophakic or aphakic bullous keratopathy with anterior chamber, iris-fixated, or no intraocular lens in place are reported.
A completely intact posterior capsule is not necessary to support safely a sulcus-fixated posterior chamber lens. Anterior segment reconstruction, careful removal of existing intraocular lenses (except a posterior chamber lens), vitrectomy through the ruptured posterior capsule, and assessment of the remaining posterior capsule rim are important surgical objectives.
Blue Field Entoptoscopy in the Preoperative Evaluation of Vitrectomy Candidates
Authors: Mittl Rainer N , Green Donald H 
Published: April 2021

ABSTRACT
Twenty-four patients with vitreous hemorrhage scheduled for pars plana vitrectomy were evaluated with the blue field entoptoscope. Correlation of preand postoperative findings in patients with and without macular pathology was highly irregular, apparently due to mechanical obstruction of light transmission by the vitreous hemorrhage. Blue field entoptoscopy is therefore not recommended as a tool in the preoperative evaluation of vitrectomy patients.
The Use of Thiphenamil Hydrochloride (Trocinate) to Control Wound Contraction After Radial Keratotomy
Authors: Garrett Charles , Presley Elizabeth , Prager Thomas C , Moorhead Louise C 
Published: April 2021

ABSTRACT
We studied the efficacy of a topical smooth muscle antagonist, thiphenamil hydrochloride (Trocinate), in inhibiting wound contraction in ocular tissue. Fifteen New Zealand white rabbits underwent standard eightincision radial keratotomy (RK), and eyes were randomly assigned to treatment or control groups. As demonstrated by slit lamp corneal photographs and by ocular histology, transient inhibition of wound contraction lasted approximately one week in all treatment eyes. We conclude that thiphenamil has a temporary, but specific, effect in controlling wound contraction after ocular surgery. Smooth muscle antagonists may be useful for managing cicatricial conditions of the eye.
Correction of Hyperopia Following Radial Keratotomy: Quantification in Human Cadaver Eyes
Authors: Lindquist Thomas D , Rubenstein Jonathan B , Lindstrom Richard L 
Published: April 2021

ABSTRACT
Overcorrection is a significant complication following radial keratotomy (RK). This study using human cadaver eyes demonstrates that the use of interrupted sutures placed across radial incisions coincident with a 7-mm optical zone mark can induce a wide range of central corneal steepening and can therefore correct varying amounts of hyperopia following RK. A case presentation confirms the effectiveness of using interrupted sutures to steepen the cornea following RK, but it also shows that significant regression of the effect must be considered at the time of suture placement. Since placement of interrupted corneal sutures is a routine procedure, it is a very convenient technique for treating overcorrection following RK.
