Surgically induced scleral necrosis (SINS) is a rare entity that has till date not been reported in a patient of glaucoma undergoing Ahmed glaucoma valve (AGV) implantation.


We present a case of primary open-angle glaucoma who underwent AGV implantation followed by development of scleral necrosis, involving both the scleral patch graft and host sclera. After failure of surgical and medical management, AGV had to be explanted. The patient was diagnosed with rheumatoid arthritis and had to be treated with steroids and azathioprine for the same.


SINS is a potentially disastrous complication of ocular surgery that can occur in patients with systemic diseases like rheumatoid arthritis and requires aggressive management to salvage the eye.


SINS can occur with AGV implantation. Treatment may require aggressive medical and surgical intervention. It is imperative to evaluate patients for systemic illness before planning an AGV implant.
