Dissociative Visual Loss in Children and Adolescents.

Psychogenic vision disorders in children and adolescents are a common disorder primarily encountered by ophthalmologists at the onset because, as with other disorders of dissociation, the presentation suggests a neurologic or other somatic condition. Loss of visual acuity, blurred vision and visual field restriction-often described as tunnel vision-appears to be typical. The onset may be sudden, frequently related to a wide range of stressful life events (school failure, family conflicts, accidents). While the majority of these children quickly recover from their symptoms, a substantial percen…
