Background: The aim of this study was to report the vision-related quality of life (QoL) in Pakistani subjects with early or moderate glaucoma.
Methods: This case control study was conducted at Al-Shifa Trust Eye Hospital, Pakistan, from 1 January 2014 to 31 December 2015. All the patients having early or moderate glaucoma, with a disease duration of at least 6 mo, and presenting during the study period, were included. Subjects in the control group were recruited from the hospital volunteer staff, spouses and friends of patients. QoL assessment was done using the NEIVFQ25 questionnaire translated into the Urdu language. A two-tailed t-test was used to test the significance of difference between the mean QoL scores and a p-value of ≤0.05 was considered significant. Multiple linear regression was carried out to assess the predictors of QoL scores.
Results: A total of 698 participants were enrolled, including 247 cases and 451 controls. The mean QoL score was higher in controls 81.31 (mean=81.31, SD=26.33) than in cases (mean=53.89, SD=30.32), p<0.001. The lowest NEIVFQ-25 scores for glaucoma patients were for mental health (mean=23.88, SD=28.80) followed by general vision (mean=27.73, SD=29.74). The difference in all the mean subscale scores of two groups was statistically significant (p<0.001).
Conclusion: QoL scores are significantly reduced in Pakistani glaucoma patients with early and moderate glaucoma, with more pronounced effect on mental health and general vision.
