Quality of life after various vitrectomy technologies in patients with proliferative diabetic retinopathy on hemodialysis

Objective: comparative assessment of quality of life (QoL) after various vitrectomy techniques in patients with proliferative diabetic retinopathy on hemodialysis. Material and methods. 72 patients (mean age 57.4±2.2 years) requiring regular hemodialysis sessions were under observation. Patients were divided into two groups (36 patients, 36 eyes) equal in age, gender and severity of proliferative diabetic retinopathy: the main group included underwent vitrectomy following the developed technique and the control group included underwent the traditional surgery. QoL investigation was performed according to a special (Assessment of Quality of Life in Patients with Vitreoretinal Pathology, QoL-20) and general (Visual Function Questionnaire 25, VFQ-25) questionnaires before and one month after surgery. Results. QoL after vitrectomy was significantly increased by both questionnaires. Comparatively, the greatest positive dynamics was revealed in the main group patients compared to the control group on the VFQ-25 questionnaire (by 20.0%, p=0.013) and the QoL-20 questionnaire (by 47.5%, p=0.008). Conclusion. The developed technique of vitrectomy in patients with proliferative diabetic retinopathy undergoing hemodialysis was characterized by higher clinical effectiveness as shown by a comparative dynamics of QoL indicator, especially according to a special questionnaire QoL-20 designed for vitreoretinal pathology.
