Abstract

 

Optic disc pallor is associated with a wide variety of disorders that affect optic nerve; including in flammatory disorders, nutritional deficiencies, and heredodegenerative disease. Cone dystrophy is rare but must be kept in mind as a cause of optic disc pallor. Electroretinography is an important diagnostic tool in diagnosis of cone -rod dystrophy. We report a case of cone dystrophy which has normal neurological findings except optic disc pathology.

Key words: Optic disc pallor, Cone dystrophy, Electroretinography.
