Quantitative assessment of metamorphopsia using M-charts and Amsler tests in patients with non-treated central serous chorioretinopathy
open access
Abstract
INTRODUCTION. The aim of this study is the assessment of the clinical parameters related to metamorphopsia using M-charts and traditional Amsler tests in patients with central serous chorioretinopathy (CSCR).
MATERIA LS AND METHODS. Seventeen eyes of 17 patients were examined with M-charts and Amsler tests, as well as with ocular coherence tomography (OCT) at each of three visits during four months of follow-up. The rate of metamorphopsia detection was 82% with M-charts and 76% with Amsler test.
RESULTS . The vertical metamorphopsia score decreased after four months in nine patients (52.9%), 0.1° on average; increased in two patients (11.8%), mean 0.2°; and there was no change in six patients (35.3%). The horizontal metamorphopsia score decreased in seven patients (41.2%), 0.2° on average, increased in three patients (17.6%), 0.23° on average, and there was no change in seven patients (41.2%).
CONCLUSIONS. M-charts are superior to the traditional Amsler charts in the monitoring of metamorphopsia in patients with CSCR. M-charts are a good diagnostic tool for quantitative assessment of metamorphopsia and monitoring over time in patients with CSCR.
