Exophoria is a form of heterophoria in which there is a tendency of the eyes to deviate outward.[1] During examination, when the eyes are dissociated, the visual axes will appear to diverge away from one another.[2]

Prevalence

Exophoria is particularly common in infancy and childhood, and increases with age.[3][clarification needed]

Cause

Exophoria can be caused by several factors, which include:

These can be due to nerve, muscle, or congenital problems, or due to mechanical anomalies. Unlike exotropia, fusion is possible in this condition, causing diplopia to be uncommon.
