title: [Fluorescent angiographic and rheographic evaluation of the ocular hemodynamics in patients with proliferative diabetic retinopathy after closed vitrectomy].
abstract: Rheo-ophthalmography has been employed in examinations of the hemodynamics in 42 patients with proliferative diabetic retinopathy, aged 21 to 78; in 16 of these patients with sufficiently transparent media the fundus oculi has been examined by fluorescent angiography. The examinations have revealed an impaired hemodynamic balance, manifesting by a low rheographic coefficient (1.55 +/- 0.12%) and a considerably longer time of the venous circulation (18.8 +/- 0.5 s). Vitrectomy not only removes neovascularization, proliferates, and changed vitreous, but also normalizes the hemodynamic parameters at the expense of shortening the venous system and removing the venous congestion.
