Status of macular area of retina of patients with advanced proliferative diabetic retinopathy and complicated incipient cataract according to optical coherence tomography
Purpose. The aim is to conduct a comparative analysis of status of macular area of retina of patients with advanced proliferative diabetic retinopathy and complicated incipient cataract according to phacoemulsification surgery time frames: after vitreoretinal surgery only or after vitreoretinal surgery as an integral component. Material and methods: 26 cases of surgery treatment of patients with PDR and complicated primary cataract were analyzed. This patients were divided into two groups depending on the treatment tactics. Retinal thickness in the fovea was measured by optical coherence tomography before surgery and 1 and 3 months after phacoemulsification cataract. Results. Visual functions improved in 85.8% of cases in group 1, and in 66.7% in group 2. Conclusion. Outcomes of the preliminary studies suggest that the frequency of macular edema development after phacoemulsification surgery and IOL implantation with vitreoretinal surgery is recorded more often than when performing with phacoemulsification surgery and silicone oil removal simultaneously by the second stage.
