DIAGNOSTIC ROLE OF OPTICAL COHERENT TOMOGRAPHY OF ANGIOGRAPHY IN PRIMARY OPEN-ANGLE GLAUCOMA

The review presents data from foreign literature on the diagnostic value of optical coherence tomography angiography (OCT-A) as a method for studying the microvasculaturc of the eye in early diagnosis and monitoring of glaucoma. Numerous foreign researchers have studied the OCT-A parameters, which provide information on the anatomy and physiology of the microcirculation of the retina and the optic nerve head. OCT-A can provide an assessment of the vasculature within the optic nerve, peripapillary superficial retina, macula, and parapapillary choroid in glaucoma. The density of the peripapillary superficial retinal vessels allows the diagnosis and detection of the progression of glaucoma, as well as the thickness of the peripapillary RNFL. A decrease in the density of the peripapillary vessels of the intact field or unaffected glaucomatous eyes indicates that vascular changes may occur before noticeable damage to the visual field.
