Anatomic and topographic features of vitreous and vitreoretinal interface in patients with rhegmatogenous retinal detachment complicated with proliferative vitreoretinopathy
The article describes the anatomical and topographical features of the vitreous body (VB) structure, revealed during chromovitectomy in 30 patients with rheumatogenous retinal detachment, complicated by proliferative vitreoretinopathy (PVR). Chromovertectomy by special technique using as a contrasting agent «Vitreocontrast» suspension is described. Using «Vitreocontrast» suspension allows to contrast the structures of the vitreous, which cannot be visualized in vivo by the modern dyes, and to study in detail the anatomical and topographical features of vitreous body structure. Experimental and clinical studies revealed the existence of VB layer, which can be formed as a result of the stratification of vitreal cortical layers and can provoke the progression of PVR and retinal detachment relapse. It was revealed that the degree of VB destruction at different stages of the PVR is correlated with the area and properties of the detected vitreous layer. The article describes in detail the changes in the anatomy of the vitreous body and the vitreoretinal interface in various stages of PVR in patients with rheumatogenous retinal detachment.
