Introduction
We developed a new metamorphopsia chart (M-CHARTS™) for the quantification of metamorphopsia. Using this chart, we investigated the relationship between the progress of retinal contraction and metamorphopsia scores using M-CHARTS™ in patients with epiretinal membranes (ERM).
Methods
Using M-CHARTS™ we quantified the changes in the metamorphopsia scores in 24 eyes of 24 patients with ERM. Follow-up periods ranged from 12 to 25 months (mean, 15.6 months). In order to quantify retinal contraction due to ERM, we composed fundus photograph images by matching the optic discs and choroidal vessels. The movement of the retinal vessels was plotted in 16 areas of macula for evaluating retinal contraction during the observation periods.
Results
There was a significant correlation between the degree of retinal contraction and metamorphopsia score (p < 0.05). Increase in metamorphopsia scores was observed in seven patients during the follow-up periods. Increase in metamorphopsia scores and decrease in visual acuity was observed in two patients. Only one patient showed a decrease in visual acuity without an increase in metamorphopsia score. It was sug-

gested that there was a relationship between the direction of the retinal contractions and the direction of the metamorphopsia.
Conclusion
M-CHARTS™ is a simple and useful method for the detection and follow-up of metamorphopsia in patients with ERM.
