title: Photographic comparison of pupillary and corneal diameters when one eye is deviated.
abstract: A method is presented for predicting the horizontal pupillary and corneal diameters when one eye is deviated. When the actual diameters are equal, the apparent diameter of the deviated pupil or cornea is equal to the cosine of the angle of deviation multiplied by the pupillary or corneal diameter of the undeviated eye.
