title: Case report: familial cone dysfunction.
abstract: Four generations of a family with hereditary retinal degeneration underwent extensive optometric evaluation, including electrodiagnostic testing. The compiled data indicate a partial cone dysfunction transmitted as an autosomal dominant trait. The optometrist's role in the diagnosis of such conditions is discussed as well as his role in family counseling. The cone dysfunction under discussion is differentiated from other tapetoretinal degenerations.
