Endoscopic Cyclophotocoagulation in Normal Tension Glaucoma
Recruiting now · Not applicable
Conditions studied: Normal Tension Glaucoma, Cataract
In brief
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.
