AIM:To evaluate the SF-36, Diabetes Specificity Quality of Life Scale (DSQL) and anxiety and depression symptoms and investigate its changes in proliferative diabetic retinopathy (PDR) by vitrectomy interventions. METHODS:The present study included 108 diabetic retinopathy (DR) patients:54 with PDR and 54 with non-proliferative diabetic retinopathy (NPDR). Each healthy control group (n =54) sociodemographically matched to DR groups was established respectively. The quality of life, anxiety and depression symptoms were evaluated and analyzed on preoperative and postoperative month 1 using SF-36, DSQL and Hospital Anxiety and Depression Scale (HADS). · RESULTS:DR patients described impaired HRQL (Health Related Quality of life, SF -36) in 6 out of 8 subscales, including ‘Body Health’, ‘Body RoleFunction’,‘General Health’,‘Society Function’,‘Emotion Role Function’and‘Mental Health’. Compared with controls, DR patients (NPDR and PDR) suffered from statistically significantly impaired HRQL (SF-36 Summary score) (P【 0.05). By surgical intervention, the anxiety and depression score were significantly reduced, while the health and quality of life (SF-36 Summary scores and DSQL scores) was improved in patients with PDR (P 【0.05). CONCLUSION:DR patients were affected in mentation and quality of life. Surgery interventions can improve SF-36, DSQL, anxiety and depression in PDR patients. 展开更多
