[Microcirculation of optic nerve head and glaucoma].

Glaucoma is a leading cause of irreversible blindness world widely. The pathogenesis of glaucoma is still not fully understood. It is proposed that the microcirculation of optic nerve head (ONH) may play an important role in glaucomatous optic neuropathy, but the hypothesis is still lack of direct evidence. In this review, we summarized the technical developments in ONH blood flow examination and findings on relationship between decreased ONH microcirculation and glaucoma. These evidences implicate that damaged ONH microcirculation involves in pathogenesis of glaucoma. (Chin J Ophthalmol, 2016, 52: 466-470).
