The vitreo -retinal traction syndrome as a complication of post -thrombotic retinopathy. Etio -pathogenesis. Clasi fication. Tactic of treatment
Posterior vitreous detachment is the consequence of changes in the vitreous gel macromolecular structure. As a result of liquefaction, going together with alterations in the extracellular matrix at the vitreo-retinal interface, the posterior vitreous cortex detaches from the retinal internal limiting membrane. Increased gel liquefaction that exceeds the degree of vitreoretinal adhesion weakening results in anomalous PVD. Pharmacologic vitreolysis is a promising new method to improve vitreoretinal surgery results and, eventually, to prevent vein occlusion related complications.
