方法：研究纳入30例(男13例，女17例)接受全视网膜光凝术治疗糖尿病视网膜病变患者。国家眼科研究所发布的视觉功能量表(VFQ-25)用来评估全视网膜光凝术治疗前后视觉相关生活质量及日常视觉功能。患者在接受全视网膜光凝术治疗前和治疗后6mo分别填写VFQ-25量表，比较视觉相关生活质量及日常视觉功能差异。运用配对t检验对治疗前后VFQ-25评分对比。

结果：全视网膜光凝术治疗前平均VFQ-25综合评分为74.79±15.7，术后平均综合评分为74.08±19.1。术前与术后的平均VFQ-25综合评分无统计学意义(P=0.875)。

结论：全视网膜光凝术(PRP)对糖尿病视网膜病变(PDR)患者在视觉相关生活质量及日常视觉功能无不利影响。

METHODS: Thirty patients(13 males, 17 females)with PDR and undergoing PRP were included in this study. Visual Function Questionnaire(VFQ-25)developed by the National Eye Institute(NEI)of America, was used to evaluate the vision-related quality of life and daily visual functioning before and after PRP. The VFQ-25 was filled in by the authors before and at 6mo after the completion of PRP in order to compare any changes in visual related quality of life and daily visual functioning. The pre and post treatment VFQ-25 scores were compared using paired t-test.

RESULTS: Mean VFQ-25 composite score before PRP was 74.79±15.7 and after PRP treatment it was 74.08±19.1(P=0.875). The difference between pre and post PRP VFQ-25 composite scores was not statistically significant.

CONCLUSION: PRP has no significant detrimental effect on vision related quality of life and daily visual functioning in patients having PDR.
