Monocular photophobia.

Uniocular eye closure in bright daylight has been considered as evidence of a binocular vision anomaly. Two groups of patients with various binocular vision anomalies were studied and compared. The control group did not manifest uniocular or binocular photophobia while the experimental group admitted frequent eye closure. The variables studied included anisometropia, refractive error, suppression, amblyopia, heterophoria and strabismus. No relations were observed between academic achievement and anomalies of binocular vision utilizing three analytical methods. Monocular photophobia was not associated with anomalous binocular vision.
