Durations, VF tests, and numbers of medications are presented as median and range due to data skewness. Mann–Whitney U test (continuous) or Fisher's exact test (categorical). OAG: open-angle glaucoma; ACG: angle-closure glaucoma; logMAR: logarithm of the minimum angle of resolution; NS/CO: nuclear sclerosis/cortical opacity; PSC: posterior subcapsular; IOP: intraocular pressure; CDR: cup to disc ratio; MD: mean deviation; VF: visual field.
