Functional Visual Loss Associated with Trauma and Athletic Club Membership in High School

摘要

We reported five cases (three boys and two girls, age range 13-17) with functional visual loss. All belonged to athletic clubs, such as soccer club, in high school, and sustained trauma during sports practice. Unilateral visual loss was common (4 out of 5 cases), and visual acuities decreased markedly to less than 20/60. Various complaints, such as visual field loss or orbital pain, were associated with the decrease in visual acuity. Two boys recovered within a few months, while two girls needed more than 21 months for recovery. Excessive sports training can be a burden on students and lead to functional visual loss in association with trauma.
