The results of a long-term study (3 to 9 months) of chorioretinal vascular occlusions resulting from injection of latex microspheres of known sizes are reported. Isolated occlusions of small retinal vessels (capillaries and precapillary arterioles) resulted in no histologic changes in the retina. Occlusion of large retinal vessels (arterioles) caused atrophic changes in the inner retinal layers...

Objective(s). The aim is to determine the possibilities of optical coherence tomography (OCT), angiography (OCTA) eye in diagnosis tuberous sclerosis and assess dynamics this rare pathological process.
 Methods. clinical case a 19-year-old patient with involvement process visual organ presented. Ophthalmological examination also related specialists are carried out. Visual acuity was right ...

We present an automated numerical method of compensating for retinal shadows in the choroid. In this method, signal extinction caused by retinal vessels is estimated by subtracting median A-scans obtained from beneath the retinal vessels and A-scans from the surrounding area. Adding the obtained offset vector to A-scans from beneath the retinal vessels allows compensating for shadows in the cho...

Purpose: Characterization of the D-glucose tnnsport acms isolated normal and diabetic rabtnt retmal vessels wing " in vitro " lriicmpxfusicm techniques. Methods: After manual dissection and caonulation of normal and diabetic retinal vessels, they were penis4 with %D-gluar;e and 'H-inulin and studied under different cqcrimental conditions. Results We observed in normal retinal vessels a signific...

PURPOSE To assess the role of astrocytes in controlling the growth of developing retinal vessels. METHODS Growth of retinal vessels in the neonatal rat retina was examined in three conditions: normal development, cyclic hyperoxia, and normoxia (1 day 70% to 75% oxygen, 1 day room air for up to seven cycles from birth, and room air for up to 16 days), and direct hypoxia (10% oxygen from postna...
