[Changes in the ocular and orbital blood flow in patients with retinal detachment treated surgically]

Sixty-eight patients with dystrophic regmatogenic detachment of the retina and 78 controls with different clinical refraction were examined by triplex scanning of the eyeball. Bloodflow parameters in the orbital artery, central retinal artery, posterior short ciliary arteries were evaluated before and in various periods after the operation. Characteristics of the bloodflow in the ocular and orbital arteries in myopia, detachment of the retina in the presence of myopic and emmetropic refraction, proliferative vitreoretinopathy of various degrees and patterns of its progress during the postoperative period were determined and time course of bloodflow parameters evaluated in some types of interventions. Hemodynamic parameters of the orbital artery and posterior short ciliary arteries were significantly related to the degree of proliferative vitreoretinopathy and its postoperative progress.
