Transitory Impairment of Vision after Light Head Trauma in Childhood

From a group of 101 children, eleven (10.9 p. c. ranging in age from 4—12) reported transient visual disturbances such as blurred vision, grey vision or photopsias immediately after a light head trauma. As to the origin of these impediments all evidence points to the occipital areas. Oculopupillary defects or pathological nystagmus phenomena were in no case associated. The frequency of pathological EEG recordings over the occipital area was statistically significant (chi-quadrat = 4.27; p ≦ 0.05). The pathogenetic mechanism may be explained by means of a local oedematous reaction.
