|
Purpose : The correlation between visual quality of life and visual function in mild glaucoma patients was investigated.
Methods : The study was conducted on 20 mild glaucoma patients who expressed their intention to participate for this study at K University Hospital in Seoul. Contrast visual acuity, contrast sensitivity, visual field devect and stereoacuity were measured, and quality of life using NEI VFQ-25 questionnaire was assessed. All measurements were statistically analyzed with the SPSS 26.0 program.
Results : In the mild glaucoma, the low contrast visual acuity was lower than normal, and decreased visual acuity and visual field loss were related to ‘dependency’ (p<0.050) in the visual life. In the contrast sensitivity, decrease of contrast sensitivity at 3 and 12 cpd in the better eye was related to difficulty of ‘distance vision’, and contrast sensitivity at 12 and 18 cpd in the worse eye was related to the difficulty of ‘near vision’, ‘peripheral vision’ and ‘total score’.
Binocular contrast sensitivity at 12 cpd was correlated with the total score of NEI VFQ-25 questionnaires (p<0.050). The stereoacuity at near was related to the ‘role difficulties’ such as limitation of hobby and job activities.
Conclusion : In the mild glaucoma patients with less visual field loss, it was revealed that a decrease in visual acuity, contrast sensitivity and stereoacuity and visual field loss could decline the quality of visual life.
