Abstract :
Purpose: To evaluate the change in retinal nerve fiber layer thickness (RNFL) using Optical Coherence Tomography after trabeculectomy in adult patients with primary open angle glaucoma (POAG).
Methods: A total of 40 eyes (30 patients) with POAG, uncontrolled on medical management were enrolled. Average and quadrant wise RNFL thickness were measured pre and post operatively at 1 week, 1 and 3 months. Data was analysed using SPSS software.
Results: Intraocular pressure (IOP) reduced from 28.55 8.47 mm Hg, 14.8 5.97 mm Hg at 1 week, 14.25 4.47 mm Hg at 1 month, 14.9 4.8 mm Hg at 3 months (p50 years and analyzed the data but no statistically significant changes were found.
Conclusion: In this study, post glaucoma filtration surgery, there was significant lowering of IOP but no difference in RNFL thickness, visual field parameters in adult POAG patients.
