Abstract

Abstract: Purpose: To quantify subjective visual metamorphopsia in newly diagnosed patients suffering from diabetic macular oedema (DME) and other macular abnormalities and to evaluate anti‐VEGF treatment effect. Methods: Patients with DME, subfoveal choroidal neovascularization (CNV) secondary to age‐related macular degeneration (AMD) or retinal venous occlusion (RVO) were recruited. Metamorphopsia score (Mscore) was calculated using M‐Charts at baseline and at the end of a series of anti‐VEGF injections. Results: Fifteen eyes of 10 patients with DME, 14 eyes of 13 patients with AMD‐CNV and five patients with RVO were included in this study. At baseline, positive Mscore was observed in 46.6% of eyes with DME, 50% of eyes with AMD‐CNV and four of five eyes with RVO. Treatment led to a complete metamorphopsia reduction (Mscore = 0) in 71.4% of DME patients, 35.7% of AMD and 0% of RVO patients. Conclusion: We suggest that the M‐charts may serve as an additional test for diagnosis and follow‐up, complementary to morphological evaluation by imaging, in diabetic patients facing their first anti‐VEGF treatment.
