Esophoria Classification and external resources
ICD-10	H50.5
ICD-9	378.41

Esophoria is characterised by inward deviation of the eye usually due to extra-ocular muscle imbalance.

Causes include:

• refractive errors
• divergence insufficiency
• convergence excess, these can be due to nerve, muscle, congenital or mechanical anomalies.

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