PRIMARY ANGLE-CLOSURE GLAUCOMA AND RETINITIS-PIGMENTOSA

The prevalence of primary open angle glaucoma in patients with retinit is pigmentosa ranges from 2-12%. To the best of out knowledge the prev alence of primary angle closure glaucoma in retinitis pigmentosa patie nts has not been reported. This study was conducted to determine the p revalence of primary angle closure glaucoma in patients with retinitis pigmentosa and the relationship between the two. We reviewed 538 reti nitis pigmentosa patients' charts seen between 1974-1987. In the Ocula r Genetic Clinic in the Hospital of Sick Children, Toronto, Canada. Th e prevalence of primary angle closure glaucoma in our retinitis pigmen tosa patients over 40 was 1.03%. We also reviewed three patients with primary angle closure glaucoma and retinitis pigmentosa. One patient h ad typical bilateral retinitis pigmentosa, one patient had bilateral s ector retinitis pigmentosa, and one patient had unilateral retinitis p igmentosa and primary angle closure glaucoma in the same eye. Our data indicate that there is a strong association between retinitis pigment osa and primary angle closure glaucoma.
