Abstract

    Purpose. To evaluate the possibility of technology bimanual 27G vitrectomy in the treatment of proliferative diabetic retinopathy.
    

    Materials and Methods. Study of 45 patients (45 eyes) with traction retinal detachment caused by proliferative diabetic retinopathy. All patients underwent three-port 27-Gauge vitrectomy. To provide additional lighting, we used two mercury illuminator 29-Gauge «Foton-2", transscleral fixed at 4 mm from the limbus. In all cases we used a technique Bimanual remove fibrovascular membranes using vitreotom. All patients underwent endolasercoagulation of retina, in 11 cases for tamponade used gas-air mixture, in 4 cases - silicone oil viscosity of 1300 cc.
    

    Results. In the postoperative period hypotension of eye was not observed. The average level of intraocular pressure on the first day after surgery was 15.3 mm hg. During the operation, noted the following features: 1. Reducing the volume of infusion and the lack of pressure changes during operation due to the valve system on the scleral ports 2. Reduction of intraoperative bleeding endovitrealnyh due to the possibility of working directly with the vessels of the retina, namely, breaking the delicate elongated loops of native vessels in the retina during removal of fibrovascular membranes, as well as the ability to control the level of the cut-off of newly formed blood vessels, which reduces the severity of bleeding. 3. Due to the adequate operation of the valve system 27-Gauge port is not "churning" of blood in the vitreal cavity, which allows you to keep a constant visualization of the fundus during surgery.
