Objective: To investigate vision-related quality of life of Chinese patients with glaucoma and to evaluate the relationship between subjective vision-related quality of life and visual function.
Methods: 102 Chinese patients with glaucoma were enrolled and divided into 2 groups: group A had daily life visual acuity ≥0.8 (70 patients) and group B had daily life visual acuity <0.8 (32 patients). According to the severity of visual field impairment, the patients in group A were divided into 2 groups: group A1 (mean deviation, <10; 49 patients) and group A2 (mean deviation, ≥10; 21 patients). Thirty patients were enrolled as a control group. All patients completed a questionnaire and received daily life visual acuity and visual field examination. Vision-related quality of life score and binocular mean deviation were calculated and analysed by Pearson relevance analysis and single factor analysis of variance.
Results: There were significant differences in the total scores for vision-related quality of life, binocular mean deviation, daily life visual acuity and self-evaluation scores between the patients with glaucoma and the control group (p < 0.001). There was a significant correlation between the total scores for vision-related quality of life and binocular mean deviation, daily life visual acuity, and self-evaluation scores in group A, group B, and the control group. There was no significant difference in age and daily life visual acuity between group A1, group A2, and the control group, but there was a significant difference in the total score of vision-related quality of life between group A and the control group (p < 0.001). Compared with the control group, the average score for dark adaptation, and reading and writing in group A1 was significantly decreased (p < 0.05).
Conclusions: There is significant correlation between the score for vision-related quality of life and visual field defects of both eyes, which can reflect the severity of glaucoma. The impairment of dark adaptation, and reading and writing capacity is most significant in the earlier stage of glaucoma in the Chinese population.
