Delayed suprachoroidal hemorrhage following viscocanalostomy.

Delayed suprachoroidal hemorrhage is a rare complication of conventional glaucoma surgery. Viscocanalostomy is one of the new surgical techniques used in glaucoma surgery that may theoretically protect against suprachoroidal effusion and hemorrhage due to the nonpenetrating nature of the procedure. Delayed suprachoroidal hemorrhage developed in a 92-year-old white woman following viscocanalostomy. This case demonstrates that the risk of suprachoroidal hemorrhage may not be completely eliminated after a nonpenetrating glaucoma procedure such as viscocanalostomy.
