Abstract

Interactive test to categorize metamorphopsia

Highlights

  • Diseases of the macula can lead to a disturbed visual impression [1]

  • A quantitative metamorphopsia measurement based on the Amsler Grid was made possible in 2015 with the development of the software “age related macular degeneration (AMD) - A Metamorphopsia Detector®” [16,17,18,19,20,21,22]

  • This study was performed to investigate whether MacuFix can distinguish between eyes with and without metamorphopsia and the one hand and between eyes with and without maculopathy on the other hand

Summary

Results

The study included 69 eyes of 23 women and 25 men. The average age was 70 ± 11 years. Inclusion criterion was OCT-documented maculopathy in at least one eye. The group with maculopathy consisted of 57 eyes: diagnoses were early age related macular degeneration (AMD) in 8, intermediate AMD in 20, late AMD in 9, diseases of the vitreoretinal interface in 11, non-AMD macular edema in 9 eyes. The smallest correctly detected magnitude difference was on average 2.12 for eyes perceiving metamorphopsia in the Amsler Grid (standard deviation SD=±1.29) and 1.15 for eyes not perceiving metamorphopsia. Eyes with macular edema (n=14) had a mean magnitude difference of 2.79 (SD=±1.47), whereas eyes without maculopathy had a mean magnitude difference of 1.08 (SD=±0.28). The difference between eyes with macular edema and eyes without maculopathy was statistically significant (α=0.05; p
