Analysis of the effectiveness of medical and laser treatment of patients with diabetic retinopathy

Aim. To evaluate the effectiveness of traditional medical and laser treatment of nonproliferative and preproliferative diabetic retinopathy. Methods. Examined was a total of 80 eyes of 66 patients with nonproliferative and preproliferative diabetic retinopathy. In accordance with the stage of the disease and the type of treatment, all patients were divided into two groups. The first group consisted of 34 individuals (39 eyes) with nonproliferative diabetic retinopathy who received medical treatment, the second group - 32 individuals (41 eyes) with preproliferative diabetic retinopathy who received medical and laser treatment. The patients had visual acuity measurement, biomicroscopy, ophthalmoscopy, refractometry, perimetry, a study of the central field of vision, and rheoophthalmography performed before surgery, after surgery (at discharge), 10 days, 6 months and 1 year postoperatively. Results. The indices of visual functions, the hemodynamic and electrophysiological parameters have the same dynamics in the first and second groups throughout the observation period. In both groups a positive effect of the performed treatment was noted, which is almost entirely offset by 6-month post-treatment, and by one year after treatment a negative dynamic develops, which is associated with the progressive course of the disease. Conclusion. The lack of effectiveness of the standard treatment of nonproliferative and preproliferative diabetic retinopathy is the justification for a search for new treatment methods.
