Clinical profile and long term outcomes of eyes with choroidal detachment following trabeculectomy

ABSTRACT

Purpose: To assess the long?term outcomes of choroidal detachments (CDs) in eyes following trabeculectomy. Methods: Retrospective comparative case series. Data of patients with CDs following trabeculectomy (5?year period) with or without cataract surgery with a minimum of 3 months of follow?up were included. Results: In total, 45 patients with CDs following trabeculectomy were included. The mean age was 63.27 ± 8.68 years, (MF = 21); 29 of 45 eyes (64.4%) had a baseline IOP of >24 mm Hg. Patients had a median follow?up of 22.2 (IQR 16.2–30.5) months. Further, 10 of 45 eyes (22.2%) had CDs following suture lysis. The median onset of choroidal detachment from the time of surgery was 16.0 (IQR 11–36) days. The mean BCVA improved from 0.62 ± 0.28 to 0.24 ± 0.27 (P < 0.001) and mean IOP increased from 4.07 ± 2.66 to 11.20 ± 5.31 (P < 0.001) at last visit. The cumulative success rates were 76.4% (95% CI 48.4–90.5) in POAG eyes and 79.3% (95% CI 62.8–89.1) in PACG eyes (P = 0.547). Medical management was the mainstay in all patients. Four of 45 (8.88%) patients underwent subsequent choroidal drainage. Conclusion: Choroidal detachment following modern?day trabeculectomy has favorable long?term visual acuity and IOP outcomes. There was no difference in the long?term surgical success of trabeculectomy with choroidal detachments in primary angle?closure and open?angle glaucoma eyes. Long?term follow?up is essential to prevent chronic hypotony and trabeculectomy failure
