When pediatric acute acquired comitant esotropia is not caused by a neurological disease.

BACKGROUND

Acute acquired comitant esotropia (AACE) is a relatively rare type of pediatric strabismus, often described as a possible presentation of intracranial pathology. The risk of having neurological disease in isolated AACE is not clear, because many previously published cases had other neurological or ophthalmological abnormalities. The purpose of this study was to analyze the incidence of neurological abnormalities in children presenting with AACE and otherwise normal neurological and ophthalmological evaluations.

METHODS

The medical records of consecutive patients >4 years of age with AACE examined by a single practitioner from 2014 to 2018 were reviewed retrospectively. The main outcome measure was the presence of neurological disease. Children with duction deficits, incomitant esodeviations, and hyperopia of >2.00 D were excluded.

RESULTS

A total of 20 children (11 males; mean age, 9.8 ± 4.1 years) were included. Mean esodeviation was 29.5Δ ± 14.8Δ (range, 10Δ-55Δ). All had an otherwise normal ophthalmological and neurological evaluations. Of the 20, 19 (95%) had normal brain neuroimaging. One child that did not have neuroimaging was followed over 2 years without developing any neurological sequelae.

CONCLUSIONS

In our study cohort, pediatric AACE not accompanied by other ophthalmic and neurological abnormalities was not a manifestation of intracranial pathology. In such cases, the decision to perform neuroimaging should take into account other factors, including caregivers' preferences and availability for close monitoring.
