Esophoria

Esophoria
Specialty	Ophthalmology

Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance. It is a type of heterophoria.

Cause

Causes include:

Refractive errors
Divergence insufficiency
Convergence excess; this can be due to nerve, muscle, congenital or mechanical anomalies.[1]

Unlike esotropia, fusion is possible and therefore diplopia is uncommon.

gollark: We need real-life PotatOS.

gollark: Apart from its use of Go.

gollark: I run that too. It's Quite Good(tm).
