Abstract
Purpose: In cases of macular hole, metamorphopsia is one of the most important symptoms, along with decreased visual acuity and a central scotoma. We investigated the relationship between the degree of metamorphopsia and the morphological appearance of macular holes. Methods: Using M‐CHARTS™ developed by ourselves, we quantified the metamorphopsia scores in 35 eyes with an idiopathic macular hole in 35 patients. Metamorphopsia in eyes with macular hole was characterized by straight lines recognized by the subject as bending toward the central scotoma. We also evaluated best corrected visual acuity (VA) and the central 10 degrees of differential light sensitivity using the Octopus 101 program M2. The size of the macular hole and the fluid cuff were measured using a scanning laser ophthalmoscope. We also evaluated the improvement in metamorphopsia scores after surgical treatment for macular hole in 22 patients. Results: A significant correlation was found between metamorphopsia score and fluid cuff size, but not diameter of the macular hole. After vitrectomy, VA improved in 14 of 22 patients and metamorphopsia scores improved in 19 of 22 patients. M‐CHARTS™ is a simple and useful method for the quantification and follow‐up of metamorphopsia in patients with macular hole.Keywords
