*P values represent comparisons between APAC, POAG and control groups using analysis of variance analysis.
†P value represent pairwise comparison between each groups using Dunn’s test.
APAC, acute primary-angle closure; POAG, primary open-angle glaucoma; PPCMv, parapapillary choroidal microvasculature.
