Aim: This study aims to determine treatment patterns, long-term intraocular pressure (IOP) and perimetric control in different glaucomas seen at a tertiary eye center. Settings and Design: Hospital-based, cross-sectional chart review of patients routinely following up at an outpatient glaucoma service. Methods: Patients with a follow-up of at least 10 years were evaluated. Their mean IOP, visual field (VF) status, and medications/surgery required at final assessment were noted. Statistical Analysis: Descriptive statistics (mean, standard deviation, and range) were used for all parameters. Results: A total of 230 patients met our inclusion and exclusion criteria, 79 having ocular hypertension with open angles or primary angle closure (PAC), 35 primary open angle glaucoma (POAG), 50 PAC glaucoma (PACG), 20 primary congenital glaucoma (PCG), 46 secondary glaucoma patients. Ocular hypertensives with open angles showed progression to POAG in 3.7%, those with PAC in 5.2%, at a mean IOP of 17.3 ± 3.37 mmHg and 17.13 ± 4.41 mmHg, respectively. A progression on Humphrey Field Analyzer was seen in 11% of POAG and PACG eyes at a mean IOP of 13.50 ± 5.07 and 13.09 ± 3.95 mmHg, respectively. Fifteen percent of primary congenital glaucomas (PCGs) showed a glaucomatous VF defect after 10 years. In secondary glaucoma eyes, the mean IOP at last follow-up visit was 12.38 ± 3.74 mmHg, with progression noted in 7.69% of eyes. Conclusion: This study provides evidence that routine delivery of care can provide well controlled IOP in glaucomas, both primary and secondary, and the VF stabilized in about 90% of patients over a period of 10 years, with the currently available glaucoma medications and trabeculectomy.
