Comparison of Phaco Surgery With Goniosynechialysis Versus Trabeculectomy in Glaucoma Treatment

This study is comparing two surgical options for patients with a type of glaucoma (angle-closure glaucoma with peripheral anterior synechiae) who also have cataracts. One option is cataract surgery combined with a procedure to open the drainage angle of the eye (goniosynechialysis); the other is a traditional glaucoma surgery called trabeculectomy. The goal is to find out which approach better lowers eye pressure while preserving vision. **You may be eligible if...** - You are 40 years or older - You have glaucoma with abnormal scarring in the drainage angle of the eye (PAS affecting more than 180 degrees) - Your eye pressure is above 21 mmHg despite taking glaucoma medications - You have a cataract affecting your vision (grade 1 to 3) - You have documented vision loss from glaucoma **You may NOT be eligible if...** - Your glaucoma is very advanced (limited to only light perception vision) - You have a secondary cause for your angle-closure glaucoma - You have had prior eye surgery or laser iridotomy - You have severe corneal disease or use chronic corticosteroids - Your cataract is very advanced (grade 4 or 5) Talk to your doctor to see if this trial is right for you.
