Objective. The annual disability index among patients with rhegmatogenous retinal detachment (RRD) is 2–9 %. One of the main factors causing the development of morpho-functional disorders of macula is the change in intraocular hemodynamics. The purpose is to study chorioretinal blood flow in patients with different visual acuities after successful endovitreal surgery of RRD.
Methods. Clinical studies consist of 30 people (30 eyes) with the full anatomic retinal attachment after endovitreal surgery of RRD with proliferative vitreoretinopathy. Depending on the level of the best corrected visual acuity (BCVA) predicted the day before surgery, the patients were divided into 2 groups. Laser doppler flowmetry and angioOCT were carried out to all patients. Based on indices of chorioretinal blood flow, the degree of severity of its changes was determined.
Results. Analysis of results indicated the presence of changes in parameters of intraocular hemodynamics of varying severity in patients with RRD before surgery and in postoperative period, depending on the stages of surgical treatment.
Conclusions. The level of recovery of BCVA directly depends on the degree of severity of the chorioretinal deficit in macula and the rate of its disappearance.
