Unusual presentations of accommodative esotropia.

PURPOSE

Most patients with accommodative esotropia are first examined between the ages of 6 months and 2 years. This paper discusses unusual presentations of accommodative esotropia that occur outside of this age-group and/or have a precipitating event that triggered the esotropia. In a series of patients who were from 5 to 11 years of age, trauma was the precipitating event. In some of the patients under 6 months of age, high myopia, as well as a moderate to large amount of hyperopia, was the cause. In 1 teenager, diabetic ketoacidosis precipitated accommodative esotropia.

METHODS

We reviewed all of our records for the past 25 years involving patients with a diagnosis of esotropia, and we found 17 patients who had unusual presentations of accommodative esotropia. Of 8 who were under the age of 6 months, 2 had high myopia and 6 had moderate to large amounts of hyperopia. Nine patients were older than age 5. Eight of the 9 had suffered trauma associated with the presentation of accommodative esotropia, and 1 patient's accommodative esotropia was associated with diabetes. The patients with myopia received their full myopic correction. The children under 6 months of age with hyperopia received their full cycloplegic refraction, and the children over age 5 received the most plus that they were able to accept in a noncycloplegic state consistent with good visual acuity (at least 20/30 in each eye).

RESULTS

In 17 patients, accommodative esotropia was initially controlled with glasses. In a few of the trauma cases, bifocals were required for control of near deviation. Only 2 of the patients, in whom onset was under 6 months of age, came to surgery. One had hyperopia controlled for 2 years with glasses, and the other had myopia controlled for 3 years with glasses.

CONCLUSIONS

Accommodative esotropia can occur prior to 6 months of age. It can also occur in older children (5 to 14 years of age) and can be precipitated by trauma or diabetic ketoacidosis.
