Evaluation of Bilateral Visual Function after Vitrectomy for Complications of Proliferative Diabetic Retinopathy

Purpose: The author evaluated the impact of vitreoretinal surgery for proliferative diabetic retinopathy (PDR) on bilateral visual function. Methods: Anatomic and visual acuity outcomes were reviewed by author for patients who underwent bilateral surgery for PDR. Bilateral visual function was evaluated using the American Medical Association (AMA) Guidelines for Disability scale to quantitate the impact of surgery on visual system disability. Results: There were 18 patients (36 eyes) who underwent vitrectomy for complications of PDR, and the overall anatomic success rate was 100%. Mean visual impairment of the study eyes and visual system according to AMA Guidelines for Disability decreased postoperatively by 22.4% points, and 25.7% points, respectively. A higher functional level of the bilateral visual system resulted postoperatively in 83.2% of all patients, according to eyes with better visual acuity. Conclusions: Vitreoretinal surgery was associated with a reduction in bilateral visual disability and improved bilateral visual function in patients with PDR.
