Article in several languages: deutsch | English

Abstract
Aim Distorted vision (metamorphopsia) is a leading symptom in retinal disease and can be categorized with the app MacuFix. This prospective controlled pilot study examined the influence of the app MacuFix as a method to assess metamorphopsia on vision-related quality of life.
Methods Forty-five patients suffering from metamorphopsia in at least one eye were recruited for the study. Vision-related quality of life before and after 3 months of optional home monitoring using the app MacuFix were compared with the questionnaire National Eye Institute Visual Function Questionnaire-25.
Results The 45 participants (18 women, 27 men) were, on average, 68 years old (SD ± 9.7) and had a mean best-corrected visual acuity of 0.6 (SD ± 0.25). Of 90 eyes, 18 revealed no maculopathy. Age-related macular degeneration existed in 52 eyes, epiretinal gliosis in 6, and macular hole in 1 eye. Macular edema was present in two eyes due to diabetes, four eyes due to uveitis, one eye after retinal venous thrombosis, four eyes because of an Irvine Gass syndrome, and two eyes caused by central serous thrombosis. After 3 months, 35 persons used the app for home monitoring, 8 persons applied the Amsler Grid, and 2 did not use any test. App users showed a highly significant improvement in vision-related quality of life in questions on mental health and concern about vision, and a significant improvement in performance, dejection, control, and embarrassing situations.
Conclusion The results suggest that MacuFix can possibly ameliorate partial aspects of vision-related quality of life.
