See related CME at Highlights of the American Association for Pediatric Ophthalmology and Strabismus Annual Meeting. PathophysiologyThis condition most commonly occurs in infants when a flat nasal bridge and prominent epicanthal folds tend to obscure the nasal portion of the sclera. This optical illusion causes the patient to have an appearance of eyes deviated nasally, and it is most apparent when the eyes are in side gaze or are focusing up close. A small interpupillary distance (ie, the distance between 2 pupils) also can give the appearance of pseudoesotropia. FrequencyUnited StatesPseudoesotropia is a condition with variable frequency. This condition is one of the most common reasons for infant referrals to ophthalmologists. RaceInfants or young toddlers of Asian descent with flat nasal bridges often have pseudoesotropia. SexNo gender predilection exists in pseudoesotropia. AgePseudoesotropia is more frequent in infants and toddlers where facial structures have not yet fully developed. CLINICALHistoryParents may notice that their young child's eyes appear to turn in. The deviation is reported to be even more noticeable when the child has a head turn and the eyes are in lateral gaze. Parents may bring pictures showing how the eyes are "turned in" to the ophthalmologist. Physical

TREATMENTMedical CareNo treatment is required for pseudoesotropia. Parents can be reassured that their child most likely will outgrow the condition. Infants should be observed and reevaluated every 6 months because it is possible that true esotropia, particularly accommodative esotropia, may develop at a later date. ConsultationsPatients with suspected pseudoesotropia should be examined and receive follow-up care by an ophthalmologist since it is possible that true esotropia may develop at a later date.
