OCT angiography in the assessment of central retinal structure under induced hypotension
https://doi.org/10.25700/NJG.2021.01.06
Abstract
Today the only available treatment option for patients with primary open-angle glaucoma is lowering intraocular pressure with medication, laser or surgical procedures. However, besides the mechanical factor, pathogenesis of glaucoma also involves the vascular factor, which in the future may become a new treatment target for slowing chronic neurodegeneration. Optical coherence tomography angiography (OCT-A) is a relatively new method for studying the microcirculation in the retina and optic nerve head. It has many advantages over other methods used for studying ocular blood flow including non-invasiveness, reproducibility and repeatability of results. Glaucoma is known to affect the hemodynamic parameters of the optic nerve head, peripapillary retina and macular region. This review analyzes available data on the effects of glaucoma surgeries and, consequently, induced hypotension on OCT-A parameters of microcirculation in the macular region.
