PURPOSE: To describe a new technique for revising oversized blebs after trabeculectomy. METHODS: A chart review of consecutive patients undergoing bleb window cryopexy was conducted. Patients with symptomatic oversized blebs were candidates for the technique, regardless of the intraocular pressure. Under topical anesthesia, the bleb was incised and a 3 x 3 mm conjunctival window was removed using 0.12 forceps and Vannas scissors. Light cryotherapy was applied to the sclera through the window. A soft bandage contact lens was then placed for compression, and a patch was applied. All patients were given antibiotic drops the first day after surgery. Topical corticosteroid drops were used to minimize postoperative inflammation. Outcome measures included relief of symptoms, adequate control of intraocular pressure, and restoration of filtering bleb function without further antiglaucoma medication or surgical bleb revision. RESULTS: Nine patients met the inclusion criteria. All patients had flattening of the bleb with symptomatic relief within two weeks. No loss of bleb function occurred. One patient developed aqueous misdirection after the procedure. CONCLUSIONS: Early results showed that bleb window cryopexy is safe and effective. This minimally invasive technique can be useful for selected patients with large. symptomatic, overhanging blebs.
