Late hypotony after cataract extraction due to a scleral fistula: a technique for surgical correction

The authors report the use of a surgical procedure for the correction of a scleral fistula in a patient with late hypotony after cataract surgery. Trephination of necrotic tissue lining the scleral fistula with a double scleral patch technique was performed. Four months later, the patient's vision had improved to 20/40, with improvement of the macular folds and an intraocular pressure of 10 mm Hg. The authors conclude that the use of a double-patching technique is effective in the repair of scleral fistulas. The technique allows one to avoid more risky repair procedures that involve a greater area of tissue excision.
