Core Messages
-
Recognition and diagnosis of the individual forms of childhood strabismus are important for the best preservation of visual function.
-
Esotropia is the most common form of pediatric ocular deviation in the West, whereas exotropia predominates in the East.
-
Accommodative esotropia is the most prevalent form of strabismus in the West, comprising half of all esodeviations.
-
Congenital, or infantile, esotropia accounts for less than 10% of all pediatric esotropia, a figure much smaller than once widely believed.
-
Intermittent exotropia is the second most common form of childhood strabismus in the West and the most commonly diagnosed form of exodeviation worldwide.
-
Hyperdeviations are uncommon, with fourth cranial nerve palsy being the most prevalent etiology.
-
Major independent risk factors associated with strabismus development include: prematurity, central nervous system (CNS) impairment, low birth weight, family history, and refractive error.
-
Recent studies have reported a decline in the number of surgeries performed for strabismus; however, population-based data of congenital esotropia in the United States confirms a more stable rate.
