简要总结
The purpose of this study is to assess whether endoscopic cyclophotocoagulation added to cataract surgery lowers intraocular pressure more than cataract surgery alone in patients with normal tension glaucoma.
详细描述
Subjects with normal tension glaucoma that is stable with current medication needing cataract surgery are recruited in the study. All patients meeting the inclusion criteria and giving informed consent will be randomized to whether having endoscopic cyclophotocoagulation performed in the same session with cataract surgery, or cataract surgery alone.
