両側被殻損傷例に生じた中枢性羞明の発現機序とそのリハビリテーション

We report a case of central photophobia after bilateral putamen injury. Although the patient complained of photophobia from the onset, he was able to perform activities of daily living without major problems. Approximately 150 days after the onset, dizziness and lightheadedness developed, which greatly interfered with his daily life. He visited various departments for detailed examinations resulting in suspicion of impairment in the vestibulo-ocular reflex. Symptoms such as photophobia, dizziness, and lightheadedness can be alleviated by colored filters. It is possible that the central photophobia in this case was caused by damage near the photophobic neural circuit. Symptoms including dizziness and light-headedness have been associated with central photophobia and may be caused by damage to a part of the photophobic neural circuit or the area adjacent to it. Furthermore, following a course of cognitive rehabilitation, tracing reading and gaze stability exercises were effective in alleviating the symptoms associated with central photophobia.
