How common is strabismus in the world?

The estimated of pooled prevalence (95% CI) of any strabismus, exotropia, and esotropia

esotropia

A successful surgery for esotropia was defined as an orthophoria of up to +10 prism dioptres of deviation for non-accommodative targets at a distance of 20 feet, measured by cover and prism test. A successful surgery for exotropia was defined as a residual deviation between -10 and +10 prism dioptres.

was 1.93% (1.64-2.21), 1.23% (1.00-1.46), and 0.77% (0.59-0.95), respectively. The heterogeneity in prevalence of strabismus and its subtypes according to I² was above 95% (p value <. 001 for all).
