[Analysis of the quality of life and the influencing factors in patients with diabetic retinopathy before and after receiving pan-retinal photocoagulation].

Objective: Quality of life and the influencing factors in patients with diabetic retinopathy before and after receiving treatment of pan-retinal photocoagulation (PRP) were studied. Methods: Prospective study. A total of 55 diabetic retinopathy patients were collected at Beijing Friendship Hospital, Capital Medical University from November 2016 to August 2017 and were surveyed using Vision Function Questionaire (VFQ-25) to evaluate their quality of life before and 3 months after treatment with PRP. According to diagnostic criteria, the patients were divided into two groups: severe nonproliferative diabetic retinopathy(NPDR) and proliferative diabetic retinopathy group(PDR). SPSS was used for statistical analysis. Results: The score of VFO-25 general health before PRP treatment was 62.73±14.20, obviously lower the other sub scale scores of VFO-25. The results of variance analysis there was significant statistical difference between the composite score and the different educational levels ( F= 2.94, P< 0.05), but there was no statistical difference for diabetes duration ( F= 3.01, P< 0.05). The composite score was significantly significance between the severe NPDR and PDR group( t= 8.95, P< 0.05). The patients with hyperlipidemia ( t =-3.21, P< 0.05), hypertension( t =-2.32, P< 0.05) and renal insufficiency( t =-2.05, P= 0.045) has lower composite score. There was high relationship for age among the factors of worse logMAR vision, better logMAR vision and age ( r =-0.47, P< 0.05; r =-0.38, P< 0.05; r =-0.26, P< 0.05). The scores of VFQ-25 subscale of social function ( t =-2.07, P< 0.05) , role limitations ( t =-2.38, P< 0.05) , dependency ( t =-2.99, P< 0.05) and mental health ( t =-2.26, P< 0.05) was significantly increased after treatment of PRP. The score of ocular pain was obviously decreased ( t= 4.19, P< 0.001) ; there were no significance in other sub scale scores. Conclusions: This study showed that the degree of visual acuity, the severity of DR and age were an important factor affecting the quality of life in DR patients. PRP therapy could improve the mental health and social field of DR patients, but failed to improve the scores of other visual functions in the patients. (Chin J Ophthalmol, 2018, 54:611-616) .
