Outcome study of stereopsis in relation to duration of misalignment in congenital esotropia.

Purpose: A recent outcome study of Randot stereopsis in congenital esotropia reported early surgical alignment is associated with a higher percentage of patients with stereopsis and a higher quality of stereopsis because early surgery minimized the duration of misalignment. We compared the Titmus stereopsis with the duration of misalignment and the age of alignment for a group of patients who were surgically aligned by 24 months of age.

Methods: The data previously obtained in a study of 90 patients aligned by 2 years of age, examined in a masked, independent evaluation for binocularity was analyzed.
