Abstract

Precis: At 6 months the procedure achieved a 33.89% drop in intraocular pressure (IOP), had an overall success rate of 57.15%, and did not change the best-corrected visual acuity. Achieving <8 mm Hg of IOP the day after the procedure may be a prognostic success indicator.

Purpose: The purpose of this study was to evaluate the first mitomycin C (MMC)-augmented needle revision in patients with failed nonpenetrating deep sclerectomy (NPDS) and factors associated with its success.

Materials and methods: This prospective, nonrandomized comparative trial included 21 consecutive patients (21 eyes) who underwent their first MMC needling revision of failed NPDS blebs. The success was defined as absolute if the IOP decreased >20% from the preoperative value without antiglaucoma treatment and as qualified if that level was achieved with antiglaucoma medications. Preoperative and postoperative factors were evaluated for an association with postoperative success using Kaplan-Meier analysis.

Results: A significant reduction in mean IOP from preoperative levels was evident at the end of the follow-up. The overall surgical success rate was 57.15%. On the basis of Kaplan-Meier survival analysis, we found that patients whose IOP on the following day of the procedure was <8 mm Hg had a higher success rate than those whose 1-day postoperative IOP was higher. These patients had a percentage of success of 100%, 84.6%, and 76.9% at 1-, 3-, and 6-month postoperative follow-up, respectively.

Conclusion: The IOP level on the first postoperative day could be considered a prognostic indicator of success in needling revision performed in failed NPDS.
