[Congenital esotropia]

Congenital esotropia is a common type of strabismus that occurs shortly after birth, though the ophthalmologist is seldom consulted at an early date. We conducted a retrospective study of 7 children of congenital esotropia who were diagnosed before the age of 6 months and underwent bilateral medial recti recession (6-7 mm) when 1.5 to 3 years old. Postoperatively, 5 patients attained normal ocular alignment (< 10 prism diopters), and 2 were undercorrected to need a second operation. The differential diagnosis and treatment of congenital esotropia were discussed.
