The paper analyses results after examination of the functional state of eye vessels in 92 patients (117 eyes) with initial stage of glaucoma and 44 persons (55 eyes) with suspected glaucoma. A control group included 31 patients (41 eyes) without any eye pathology. For assessment of the functional state of eye vessels, cryorheographic test was used. Main types and variants of neurovascular reactions of the eye were determined. Reduced vascular tonus was recorded in most of the subjects. Glaucomatous, patients showed predominantly organic changes in the vascular bed of the eye. In persons with suspected glaucoma, the incidence of functional and organic changes of the vessels was approximately the same. In healthy persons, functional changes were observed more frequently. A conclusion is made that the functional state of the vascular bed of the eye should be considered when prescribing medicamentous treatment for glaucomatous patients.

Coats-like response refers to a condition where abnormal telangiectatic retinal vessels and aneurysms associated with subretinal exudation are seen in the setting of other ocular or systemic diseases. So far, it has been described with various ocular disorders like retinitis pigmentosa, chronic ischemic branch retinal vein obstruction and pars planitis. A man in his 30s presented with a 1-month history of diminution of vision in the left eye.

Purpose: Bietti crystalline dystrophy (BCD) is a rare retinal dystrophy characterized by progressive visual impairment. This study aimed to evaluate changes in retinal and choroidal vessels and blood flow in BCD patients using swept-source optical coherence tomography angiography (SS-OCTA) and to investigate potential parameters associated with visual function.
Methods: This cross-sectional study included 166 eyes from 86 clinically diagnosed BCD patients, classified into three disease stages based on Yuzawa's classification.

Background: To compare structural and vascular parameters between advanced pseudoexfoliation glaucoma (PXG) and primary open-angle glaucoma (POAG).
Methods: One hundred and six eyes of 81 patients were enrolled in this cross-sectional study. All patients underwent complete ophthalmic examination and measurement of the thickness of the peripapillary retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC).

Background: To establish an objective method for assessing plus disease severity in retinopathy of prematurity.
Methods: Six images of plus diseases that were color-coded according to severity and published in the International Classification of Retinopathy of Prematurity, Third Edition (ICROP3) were analyzed. These images were individually processed, and the best-fit curve and vessel course in zone I were obtained using ImageJ software.
