Abstract

Purpose: To determine whether hypotony after filtration surgery has any influence on visual acuity and intraocular pressure (IOP) lowering. Patients and Methods: We prospectively investigated 43 eyes of 43 patientsundergoing trabeculectomy without the use of antimetabolites for 12 months. Results: The lowest postoperative IOP valued 4.9 +/- 3.6 mm Hg (range, 0-14 mm PIE). It correlated statistically significant with the IOP 6 weeks (P = 0.016), 6 months (P = 0.009), and 1 year after surgery (P = 0.027). Eyes with a deterioration of visual acuity 6 weeks after surgery had undergone astronger postoperative hypotony (correlation with lowest postoperative IOP, P = 0.035). The mean period with an IOP less than 5 mm Hg was 3.5 +/- 8.0 days, and the mean period with an IOP less than 10 mm Hg lasted 45.4 +/- 68.8 days (range, 0-276 days). A hypotony score based on IOP and duration of hypotony wasintroduced. A correlation was detected between morphologic signs of hypotony, such as tiny retinal folds, at the 6-month follow-up and the duration of hypotony (P = 0.029) and hypotony score (P = 0.001). Conclusions: Hypotony after filtration surgery may decrease visual acuity in the early postoperative period. Conversely, early postoperative hypotonycorrelated with better long term IOP control. There was no deleterious effect on visual acuity after 6 months.
