  • Abstract
  • Look Inside

A 13-month-old male infant presented with leukocoria and exotropia in his left eye. The affected eye showed an atypical choroidal coloboma involving the peripapillary area. Flash visual evoked potential (FVEP) under hypnosis showed a small amplitude with prolonged latent time in the affected eye. Simultaneously performed electroretinogram (ERG) showed a poor response. Computed tomography (CT) showed 27mm as the axial length of the left eyeball and a thinning in the posterior fundus area corresponding to the site of choroidal coloboma. Three-dimensional helical CT also showed a thinning in the posterior fundus area both by endoscopic and volume-rendering imaging. More detailed imaging was not possible bue to low threshold of the lesion.
