Effect of visual stimulation using color looming disc in Anton syndrome: a case report.

Objectives: Anton syndrome is arare stroke syndrome that develops after damage to both occipital lobes, leading to cortical blindness and visual anosognosia. This report describes the rehabilitation course and functional progress of a 42-year-old man diagnosed with Anton syndrome.Methods: The patient started visual stimulation therapy using a color looming disc 5 months after Anton syndrome onset, for 30 minutes a day, 5 times a week for 4 weeks, totaling 20 sessions.Results: After 4 weeks of visual stimulation therapy using color-looming discs, reading tests for consonants, numbers, words, and colors and the latency of the P100 of Visual Evoked Potential showed improvement. Additionally, improvements were noted in the Modified Barthel Index and Mini-Mental State Examination scores related to visual function.Conclusions: This case illustrates the effectiveness of visual stimulation therapy using color-looming discs and its potential to achieve positive outcomes.
