Leber's optic neuroretinitis is a particular form of optic neuropathy
characterized by swelling of the optic disc and a stellate pattern of
exsudative deposits in the macula. It occurs most often in healthy you
ng subjects who have acute monolateral visual loss, often preceded by
presumed viral illness. The etiology is unknown and viral infection ha
s been suggested in the pathogenesis of this condition. The prognosis
for visual recovery is reported to be excellent, but late visual seque
lae have been described: loss of vision or visual field loss. This ent
ity should be recognized and distinguished from more serious diseases
causing septic neuroretinitis or papillitis.
