ROLE OF ISCHEMIA IN THE PATHOGENESIS OF DIABETIC VITREOPAPILLARY TRACTION SYNDROME

Objective: to evaluate the role of ischemia in the pathogenesis of diabetic vitreopapillary traction syndrome. Material and methods: The analysis is based on a sample of 30 patients with diabetic vitreopapillary traction syndrome. The study included a standard ophthalmological examination, color doppler mapping, fluorescent angiography. All patients underwent three-port vitrectomy to eliminate traction syndrome. Results: The results of the obtained data indicated that patients with diabetic vitreopapillary traction syndrome had significant changes in the hemodynamics of the eye compared to the normal parameters. A significant difference in a blood flow parameters in the posterior short ciliary arteries system was recorded in eyes with vitreopapillary traction syndrome compaired to paired eyes. Conclusion: The results of the studies indicate that patients with diabetic vitreopapillary traction syndrome have significant changes in regional hemodynamics: a decrease in blood flow velocity in the central retinal artery, posterior short ciliary arteries and an increase in peripheral vascular resistance, which indicates ischemia of the optic nerve head and may also be one of the reasons for the development of vitreopapillary traction.
