Purpose:
To evaluate visual function disorder in patients with branch retinal vein occlusion by quantifying the degree of metamorphopsia.
Design:
prospective interventional case series.
Subjects And Methods:
The subjects were 12 patients(12 eyes) whose fovea was involved with branch retinal vein occlusion within a month after noticing their symptoms. The best-corrected visual acuity, and vertical and horizontal metamorphopsia scores were obtained within one month, and at 3 months and 6 months after the onset of symptoms regardless of therapy. The metamorphopsia scores were measured with M-CHARTS.
Results:
Although the average best-corrected visual acuity at 6 months was significantly better than that within a month of noticing symptoms, the average metamorphopsia scores did not improve after 6 months, and were not related to the average best-corrected visual acuity in either vertical or horizontal lines.
Conclusions:
The degree of metamorphopsia measured with M-CHARTS is an important parameter in addition to the best-corrected visual acuity for evaluating visual function in patients with branch retinal vein occlusion.
