במאמר מתוארים קשיי לידתו של הכנס השנתי לנוירו-אופתלמולוגיה בישראל. בימים אלו, באי הכנס חוגגים 25 שנים לקיומו, כאשר מיטב הנוירו-אופתלמולוגים בעולם היו אורחיו. לדעת רבים, הכנס תרם לעלייה במספר הרופאים המומחים בנוירו-אופתלמולוגיה בארץ וברמה המדעית של התחום בארץ. כיום, נוכחות הנוירו-אופתלמולוגיה הישראלית מרשימה בבמה הבינלאומית, בעבודות מחקר חשובות ובכנסים הבינלאומיים.

הכנס השנתי של ה-AAO נערך השנה באורלנדו, פלורידה. זהו כנס העיניים הקליני הבינלאומי המקיף ביותר ומשתתפים בו בדרך-כלל בין 15,000 ל-20,000 אנשי מקצוע. מלבד תערוכה מקצועית מגוונת ביותר, מתקיימים במסגרת כנס זה עידכונים בכל תת-המקצועות השונים ברפואת העיניים. כנס זה מאפשר בנוסף מיפגש בלתי אמצעי עם טובי מומחי העיניים בעולם, ורבים מרופאי העיניים בישראל משתתפים בו באופן קבוע והציגו בו מעבודותיהם. ממיגוון הנושאים שהוצגו ברצוני להדגיש מספר נקודות שהועלו במהלך הכנס העשויות לעניין גם את הרופאים הפנימאים.

Retinal Lesion due to Excessive Exposure to Sunlight

Retinal damage caused by direct exposure to the sun's rays is well recognized by the ophthalmic community. Although functional ability in solar retinopathy is usually regained within weeks, some suffer long-term visual impairment. Anatomic damage to the retina, even in those who regain full vision, is permanent. We describe 2 cases of solar retinopathy, 1 of which remained with permanent loss of vision. The role of medical education in preventing damage from solar retinal hazards is stressed.

Nonpenetrating Deep Sclerectomy

Ophthalmology Dept., Tel Aviv-Sourasky Medical Center

This is the first report from Israel of nonpenetrating deep sclerectomy (DS), a new operation for the surgical management of glaucoma. It facilitates ocular fluid drainage without entering the eye. It involves performance of a conjunctival flap and creation of a 565 mm superficial scleral flap. A deeper scleral flap is dissected off the scleral bed together with the roof of the canal and corneal stroma, leaving behind the wall of the canal and membrane. Aqueous will flood the dissected area. A collagen device is then sutured to the scleral bed, the superficial scleral flap sutured into position and the conjunctiva closed. With this procedure, the surgeon can avoid the common complications of conventional glaucoma surgery.

We report a 6-month follow-up of 15 patients after DS. Mean preoperative intraocular pressure was 26.7+2.5 mm Hg, which decreased to 15.5+4.7. After 6 months there was no change in visual acuity after surgery. DS is associated with good middle-term intraocular pressure control and a low rate of postoperative complications. It is therefore a good alternative to standard glaucoma surgery.

During the period 1985-95 we treated 5 girls and 13 boys with optic glioma associated with Type 1 neurofibromatosis (median age 3 years, range 2-10 years). 6 were treated with radiotherapy alone, 1 with surgery and radiation therapy and 1 with chemotherapy in order to postpone irradiation to an older age; 1 is being followed with no therapy. All children are alive, 2-10 years from diagnosis (mean follow-up time 5.4 years). 3 had improvement of vision following therapy and in 4 visual ability stabilized, including the child being followed without treatment. In 1 vision deteriorated despite therapy.

Toxic Optic Neuropathy caused by Methanol Poisoning

A 40-year-old woman attempted suicide by drinking methanol. Her visual acuity began to deteriorate 36 hours later and was found to be 6/60 in her right eye with no light perception in the left. No systemic manifestations other than the eye symptoms were found. In the following months visual acuity improved without specific therapy. 2 months following the methanol, visual acuity was 6/6 in the right eye and finger-counting at 1 meter in the left eye. There was pronounced optic atrophy in the left eye, as well as a central defect in the left visual field due tothe methanol toxicity.

Prevalence of Pigmentary Dispersion Syndrome in Israel

Pigmentary dispersion syndrome is a precursor of pigmentary glaucoma whose prevalence in the urban population of USA was found to be 2.45%. We evaluated its prevalence during ocular screening examinations among normal Israelis. We screened for excessive pigmentation on the corneal endothelium with the slit-lamp and determined in each patient best corrected visual acuity, intra-ocular pressure (after mydriasis), condition of the anterior segment, cup-disk ratio, posterior segment abnormalities and questioned about history of any ocular disease and family history of glaucoma. 374 patients (mean age 49±11) were examined on 10 consecutive days. In 5.9% excessive corneal endothelial pigmentation was found. Intra-ocular pressure (after mydriasis) averaged 15.52±1.93 mm Hg as compared to 14.73±2.04 among the rest of our study population, (p=0.01). The prevalence of suspected pigmentary dispersion syndrome among young adults in Israelis is high.

A prospective study of the effect of cataract extraction with intraocular lens implantation on the course of diabetic retinopathy (DR) in 44 patients (59 eyes) was carried out. It showed that in the 1-3 years following surgery, there was progression of DR (including development of newly formed retinopathy) in 35% of the patients (28.8% of eyes). Progression was more marked in patients with pre-operative bilateral DR compared to those without bilateral DR (77% and 16% respectively). Insulin dependence did not play a role in progression. Final visual acuity was better in patients without pre-operative DR, as well as in eyes without progressive retinopathy.
