目的探討視網膜病變對糖尿病病患生活品質之影響及相關因素。
方法本研究為橫斷性研究，以立意取樣，研究對象為2017年10月至2018年1月，至某醫院眼科門診就醫之糖尿病患。以SF-36v2健康生活品質量表，結構式問卷及病歷查閱等收集資料，統計分析方法包含t-test、卡方及線性複廻歸模式。
結果有效問卷共263份，糖尿病視網膜病變者115位，SF-36v2各構面中，有視網膜病變者之生活品質分數，均較無視網膜病變者低。控制相關變項後，視力是影響生理面向生活品質的顯著因素，有、無視網膜病變，對生理面向生活品質之影響無顯著差異；單眼視網膜病變者心理面向生活品質，顯著低於無病變者。
結論視網膜病變者之生活品質分數，普遍低於無視網膜病變者，糖尿病患宜預防視網膜病變。

Purposes To evaluate the impact of retinopathy on the quality of life of diabetic patients and its related factors.
Methods This is a cross-sectional study with purposive sampling. The subjects of this study included diabetic patients who visited the ophthalmology clinic in a hospital from October 2017 to January 2018. Data were collected by the self-development structured questionnaire, Psychometrics of the Short Form 36 Health Survey Version 2 (SF-36v2), and review of medical records. Statistical analysis methods included Student’s t-test, chi-square test, and linear regression model.
Results A total of 263 valid questionnaires were collected, among which 115 respondents had diabetic retinopathy. Analyses of SF-36v2 revealed that the respondents with retinopathy displayed a lower quality of life scores than that of respondents without retinopathy. After controlling for the related variables, the binocular parallax was found to be a significant factor affecting the physiological quality of life, and there was no significant difference in the physiological quality of life between those with and without retinopathy; the psychological quality of life of patients with monocular retinopathy was significantly lower than that of patients without retinopathy.
Conclusions This study concluded that the quality of life scores of patients with retinopathy were generally lower than those without retinopathy; hence, diabetic patients should take appropriate measures to avoid retinopathy.
