Exophoria

Exophoria is a latent outward deviation of the eyes, controlled by fusion, manifesting on cover test or decomensating when tired/distant. It is common and often asymptomatic. Treatment: convergence exercises/orthoptics for symptomatic; base-in prism for near symptoms; strabismus surgery for large, symptomatic, decompensating exophoria.
