Intraoperative binary contrast as a way to prevent the development of proliferative vitreoretinopathy

The risk of recurrence INCREASED in the postoperative period varies from 3 to 30%. Among the recurrence rates after successful surgical treatment, the progression of PVR is an established cause in 60% of cases, being one of the most serious complications occurring in the postoperative period. The purpose of the study: To evaluate the effectiveness of surgical treatment of retinal detachment using intraoperative binary contrast. Materials and methods. The study included 80 patients with retinal detachment up to 1 month. The patients were divided into two groups of 40 eyes each: The main group was using IBD. The control group underwent a standard vitrectomy without IBD. Results. At the initial stage, visual acuity indicators (MCI) were comparable in both groups. During follow–up (up to 12 months), both groups showed a significant improvement in ICOS, with more pronounced dynamics in the main group (with IBD), especially noticeable after 12 months - more than twice as much as in the control group. In a number of cases, relapses and complications such as proliferative changes, such as stellate membrane or epimacular fibrosis, as well as cases of previously undetected retinal tears, have been reported. Evaluation of the OCT data showed that the structure of the retina, including the CTS, remained stable without significant differences between the groups throughout all periods.
