[Ocular neuromyotonia after radiation therapy].
Ocular neuromyotonia is a rare disease that is diagnosed mainly in patients treated with radiation. All such patients described in the literature presented with temporary diplopic images as a common symptom. In our case, the patient described an abducens paresis of the right eye combined with a sporadic exotropia half a year after radiation treatment of an epipharynx carcinoma. An adduction deficit on the right side could be triggered by holding the gaze to the right over a longer period of time, leading to exotropia in the primary position and gaze to the left. Symptoms were reduced with carbamazepine.
