Summary

This study tests a new, less invasive drainage procedure for people with advanced neovascular glaucoma whose eye pressure remains high despite treatment. The goal is to safely lower eye pressure and reduce the need for pressure-lowering drugs. The study involves 30 participants and will measure success by how well eye pressure is controlled after surgery.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Advanced (angle-closure) neovascular glaucoma with poorly controlled intraocular pressure (IOP \> 21mmHg) after medical or surgical treatment Exclusion Criteria: * Various other types of glaucoma (including primary open-angle glaucoma, primary open-closed glaucoma, normal tension glaucoma, juvenile glaucoma, congenital glaucoma, other special types of glaucoma, etc.) * Eye infection within two weeks before surgery * Non-glaucomatous intraocular diseases that affect intraocular pressure (choroidal hemorrhage or detachment, retinal detachment, lens subluxation, thyroid eye disease, clinically significant macular edema, eye tumors, etc.) * Visual acuity of non-study eyes \< 0.05 * Congenital or acquired factors lead to ciliary body anatomical abnormalities
