Vascular insufficiency in normal tension glaucoma: A prospective cohort study

Abstract

Abstract Glaucoma is a disease that causes axonal loss of the optic nerve, resulting in scotomas in the visual field. Glaucoma is also the major cause of blindness. Hayreh identifies the long posterior ciliary artery,short posterior ciliary artery and centripetal branch in his "Study of the blood supply of the optic nerve head". Lee et al found delayed perfusion of adjacent parapapillary choroidal perfusion in the prelaminar region in indocyanine green angiography of primary open angle glaucoma. In the present study, we found Vascular insufficiency of centripetal branches In other words, the adjacent parapapillary choroidal perfusion of Lee et al corresponds to the centripetal branch of Hayreh. In fact, the running of the adjacent papillary choroidal circulation of Lee et al was centripetal in figures. Furthermore, in a prospective cohort study, we found that as vascular insufficiency developed, the dark spots also expanded correspondingly, suggesting a causal relationship between VI and scotoma
