In cases in which filtration surgery such as trabeculectomy is necessary, a flat anterior chamber postoperatively due to overfiltration may cause severe problems in the control of intraocular pressure. Once a broad synechia has formed between the iris and the corneal endothelium, this type of refractory, surgically induced angle closure can be difficult to manage. This article details a case of refractory angle-closure glaucoma secondary to a flat anterior chamber following trabeculectomy. Multiple surgical treatments were performed to control intraocular pressure and to reconstruct the anterior segment of the eye.
