The document summarizes a study on the effectiveness of drainage surgery for treating newvascular glaucoma in patients with diabetes. 75 drainage surgeries were performed over 5 years in patients with diabetes and newvascular glaucoma. The surgeries significantly reduced intraocular pressure and pain. Early postoperative complications included hemorrhage in 33.3% of patients and cataract formation in 9.3%. Late complications included iris capture in 6.7% and tube exposure in 1.3%. The conclusion is that drainage surgery should be the standard treatment for newvascular glaucoma in diabetes patients, especially when diabetes is well-controlled, and it requires collaboration between ophthalmologists, endocrinologists, and anesthes
