To compare the quality of life assessed by the Low Vision Quality of Life Questionnaire (LVQOL) and National Eye Institute Visual Function Questionnaire (NEI VFQ-25) in patients with low vision.
A total of 64 consecutive patients who presented to the Ankara University Low Vision Rehabilitation Department for the first time were included in the study. Patients aged 18 or older who had a best-corrected visual acuity of less than 20/60 or a visual field of equal to or less than 20° from the fixation point in the better eye were included. After examination, the patients were asked to complete the LVQOL and NEI VFQ-25 questionnaires.
A very strong correlation was found between the total scores of the two questionnaires. A strong correlation was found between the "distance vision" subscale score of LVQOL and "distance activities" subscale score of NEI VFQ-25. There was also a strong correlation between the "reading and fine work" subscale score of LVQOL and "near activities" subscale score of NEI VFQ-25. There was a weak correlation between the LVQOL total score and visual acuity. There were moderate negative correlations between age at disease onset and the total scores of the two questionnaires.
Both the LVQOL and NEI VFQ-25 are able to quantify the quality of life of individuals with low vision and it is possible to compare the studies carried out with these two questionnaires which are validated in Turkish.
比较低视力生活质量问卷（LVQOL）和国家眼科研究所视觉功能问卷（NEI VFQ-25）评估低视力患者生活质量的差异。
本研究共纳入 64 例首次到安卡拉大学低视力康复科就诊的患者。纳入标准为年龄≥18 岁，最佳矫正视力＜20/60 或优势眼固视点视野≤20°。检查后，患者需完成 LVQOL 和 NEI VFQ-25 问卷。
两种问卷的总分之间存在很强的相关性。LVQOL 的“远距离视力”分量表评分与 NEI VFQ-25 的“远距离活动”分量表评分之间存在很强的相关性。LVQOL 的“阅读和精细工作”分量表评分与 NEI VFQ-25 的“近距离活动”分量表评分之间也存在很强的相关性。LVQOL 总分与视力之间存在弱相关性。发病年龄与两种问卷的总分之间存在中度负相关。
LVQOL 和 NEI VFQ-25 均可量化低视力个体的生活质量，且有可能对这两种已在土耳其验证的问卷进行的研究进行比较。
