Between-group comparisons were performed with Student’s t-test for all parameters. Fisher’s exact test was only used for glaucoma subtype and surgery. Data are presented as mean (95% CI), except for age, which is presented as the median (quartile).
*P<0.05 was considered significant.
BCVA, best-corrected visual acuity; CD, choroidal detachment; ERG, electroretinography; IOP, intraocular pressure; logMAR, logarithm of the minimum angle of resolution; MD, mean deviation; n.a, not available; NTG, normal tension glaucoma; PACG, primary angle-closure glaucoma; PEA, phacoemulsification and aspiration; POAG, primary open angle glaucoma; PXFG, pseudo-exfoliation glaucoma; RNFL, retinal nerve fibre layer.
