Complications of Glaucoma Surgery



This chapter will review the management of complications of glaucoma surgery, specifically of guarded filtration procedures (trabeculectomy). Overall, severe visual loss is uncommon, but the incidence of transient complications (e.g., early postoperative hypotony, mild hyphema) is relatively high. Some rare complications can be very severe, such as suprachoroidal hemorrhage and endophthalmitis, potentially leading to permanent visual loss.

The frequency, risk factors, management, and strategies to prevent complications will be discussed, including hypotony and overfiltration, choroidal effusions, hypotony maculopathy, suprachoroidal hemorrhage, hyphema, malignant glaucoma, wipeout, early and late bleb leak, early and late failure of filtering bleb, bleb encapsulation, symptomatic bleb, cataract, and bleb-related ocular infection. Most adverse events can be prevented with proper surgical technique. Current best practices for each of the complications will be discussed with a pragmatic point of view.
