To evaluate the correlation between quality of vision (QOV) and visual function in glaucoma patients.
The relationship between QOV and visual function was investigated in 200 Japanese glaucoma patients. QOV was assessed using the Japanese version of the 25-item National Eye Institute Visual Function Questionnaire. The better eye and the worse eye were defined based on the mean deviation (MD) value of the Humphrey Field Analyzer program 30-2. A single linear regression analysis was applied to assess the relationship.
The lowest subscale score was observed in general health followed by general vision and driving. Visual acuity and the central 10° MD value in the better eye and the central 30° MD value in the worse eye were highly correlated with QOV. Threshold MD values at which patients began to have lower QOV ranged from -2 to -12 dB in the better eye and from -7 to -16 dB in the worse eye.
Loss of visual function in both the better and the worse eye is significantly correlated to QOV. QOV of glaucoma patients begins to decrease in the early stages of visual field defects.
评估青光眼患者的视觉质量（QOV）与视觉功能之间的相关性。
对200例日本青光眼患者的QOV与视觉功能之间的关系进行了研究。使用25项美国国立眼科研究所视觉功能问卷的日文版评估QOV。根据Humphrey视野分析仪程序30-2的平均偏差（MD）值定义较好眼和较差眼。应用单线性回归分析来评估两者之间的关系。
在总体健康方面观察到最低的子量表得分，其次是总体视力和驾驶。较好眼的视力和中央10°MD值以及较差眼的中央30°MD值与QOV高度相关。在较好眼中，患者开始出现较低QOV的阈值MD值范围为-2至-12 dB，在较差眼中为-7至-16 dB。
较好眼和较差眼的视觉功能丧失均与QOV显著相关。青光眼患者的QOV在视野缺损的早期阶段就开始下降。
