Continuous variables are given as means ± SD. Statistical comparisons of the POAG and control groups were made with an independent-samples two-tailed t-test.

RV, retinal vessel; RNFLT, retinal nerve fiber thickness; POAG, primary open-angle glaucoma; T, temporal; TS, temporal superior; TI, temporal inferior.
