Parapapillary choroidal microvascular density in acute primary angle-closure and primary open-angle glaucoma: an optical coherence tomography angiography study.

Back Ground/aims: To determine whether parapapillary choroidal microvasculature (PPCMv) density, measured by optical coherence tomography angiography, differed between acute primary angle-closure (APAC), primary open-angle glaucoma (POAG) and controls.

Methods: This is a prospective, cross-sectional, observational study. Data from 149 eyes from two academic referral centres were analysed.
