Purpose: High-pressure glaucomas and cataracts are the most frequent causes of preventable and curable blindness in Oman. The role of PEX for glaucomas and complicated cataract surgeries with ensuing blindness is studied.
Method: In the year of 2002, 498 cataract eyes (370 senile cataracts) and 88 glaucoma eyes for surgery were prospectively examined for PEX biomicroscopically, histologically (anterior lens capsule/trabecular meshwork), and by optic disk analysis (OCT2).
Results: PEX and cataracts: Of 370 senile cataracts 171 had PEX (30-39 yrs: 1(1 male(m), 0 female(f)), 40-49 yrs: 1 (3m,7f), 50-59 yrs: 42 (24m,18f), 60-69 yrs: 77 (48m,24f), 70-79 yrs:28 (17m,11f), >79 yrs:13 (5m,8f). The youngest patient was 35 yrs years old. Preoperative findings included vitreous in the anterior chamber in 15 eyes, a subluxation of the lens in 89 (6x into the anterior chamber), and a lens dislocation into the vitreous in 7.
PEX and glaucomas: Of 88 glaucomas 53 had PEX (40-49 yrs: 5 (2m,3f), 50-59 yrs: 19 (14m,5f), 60-69 yrs: 20 (12m,8f), 70-79 yrs: 8 (4m,4f), >79 yrs:1 (1f). Other g
