Holmium laser sclerostomy in glaucomatous eyes with prior surgery: 24- month results

BACKGROUND AND OBJECTIVE: To evaluate the effectiveness of holmium laser sclerostomy in glaucoma patients who have had prior intraocular surgery. PATIENTS AND METHODS: The authors conducted a retrospective analysis of outcomes for 25 patients who underwent holmium laser sclerostomy from 1991 to 1993. RESULTS: Postoperative success (defined as a drop in intraocular pressure of 30% and a final intraocular pressure of less than 22 mm Hg) at 24 months ranged from 36% to 52%, depending on criteria chosen for success. There were no major complications from the procedure. CONCLUSIONS: Holmium laser sclerostomy can be successful in a highly select group of patients undergoing filtration procedures who have had prior intraocular surgery.
