Spontaneous resolution of infantile esotropia.
OBJECTIVE
To report the spontaneous resolution of infantile esotropia in 3 patients.


METHODS
The clinical histories and the results of ophthalmologic examinations in 3 patients with infantile esotropia were reviewed and analyzed with reference to the literature.


RESULTS
All 3 patients with infantile esotropia were diagnosed with 25 to 30 PD of esotropia before the age of 6 months. All of them had insignificant refractive errors. Against medical advice, they were not brought in for follow-up examinations. At the age of 34 months to 59 months, the esotropia of the patients had changed into exophoria, esophoria less than 4 PD, or orthophoria. All patients eventually showed dissociated vertical deviation and overaction of the inferior oblique muscles. Of the 2 cooperative patients, 1 consistently identified Titmus stereograms with 3000 seconds of arc and fused Worth 4 dots at near and at distance. The other patient could not identify stereo targets and suppressed one eye on Worth 4 testing at distance, though she showed no suppression at near.


CONCLUSIONS
In these cases, infantile esotropia with a relatively small angle may spontaneously resolve without any treatment. However, all these patients showed poor stereoacuity, dissociated vertical deviation, and overaction of the inferior oblique muscles.
