Abstract

To examine how patients receiving trabeculectomy manage their IOP over the long term. To investigate how individuals undergoing trabeculectomy regulate their IOP. To research bleb morphology in trabeculectomy patients. Methods: A prospective observational cohort study was conducted between December 2021 and November 2022 on 52 patients with moderate to severe glaucomatous damage who presented to the Department of ophthalmology at Narayana Medical College & Hospital. Result: 19 eyes of two under-50 patients exhibited poor post-op IOP control. 31 eyes of three under-50 patients exhibited good post-op IOP control. Nonsignificant (P > 0.05). Beta blockers were utilised in 6 of 21 post-op IOP-uncontrolled eyes. Beta blockers controlled post-op IOP in 11 of 29 eyes. Nonsignificant (p> 0.05). 8 of 9 poor 1-year post-op IOP control eyes had POD IOP >13mmHg. 10. 12 of 41 eyes with good 1-year post-op IOP management had POD 10 IOP >13mmHg. Significant at <0.05. Conclusion: Trabeculectomy showed 59.2% complete success and 92.2% qualified success in this prospective, observational study. In POAG, 51% and 96% passed. PACG's qualifying success rate is 98% and overall success is 69%. Post-operative IOP above 10mmHg on day 5 or 13mmHg on day 10 increased the risk of poor IOP control at one year. Vascularization at six and one year was associated with flat bleb after three months of steroid discontinuation. Bleb morphology does not alter long-term IOP control after one year.
