  • Abstract
  • Look Inside

A 16-year-old male presented with recent blurring of vision in his right eye. Funduscopy showed an enlarged optic disc with a tiny pit at the temporal edge of the cup. There was a discrete retinal detachment of the macula toward the optic disc and a typical coloboma of the choroid inferior to the optic disc. He was diagnosed as pit-macular syndrome with a typical coloboma of the choroid. Fluorescein angiography revealed hypo-fluorescence from the pit toward the inferotemporal margin of the optic disc, so the optic disc was thought to be undermined deeply toward the inferotemporal margin. No leakage of dye was observed. One week later, photocoagulation was performed along the tem-poral edge of the optic disc, but was unsuccessful in reattaching the macula. These findings seemed to suggest that the subretinal fluid was derived from the cerebrospinal fluid via the pit. The pit of the optic nervehead was thought to be closely related to incomplete closure of the fetal fissure.
