The effect of cycloplegia on the determination of refractive error by the Ophthalmetron.

The Ophthalmetron was used to measure the refractive error of 10 male optometry students. Although there was a high incidence of invalid readings, more repeatable results were obtained with use of a cycloplegic. Measurements made under cycloplegia revealed 0.41 D more hyperopia but no differences in astigmatism as compared to the noncycloplegic refraction. Instrument myopia was shown not to be a factor.

Case report: familial cone dysfunction.

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.
