Abstract: Purpose: To study the clinical manifestations and surgical outcome of infantile esotropia.

Methods: This review retrospectively examined 165 patients of infantile esotropia who had undergone recession of bilateral medial rectus muscles from April 1991 to September 2001 at our institute. We measured the binocular alignment and analyzed the long term surgical outcome.

Results: The average angle of deviation of 165 patients was 45.9 +/- 13.99PD (25 ~ 90PD) and the average refractive error was +sph 1.18 +/- 2.25D (-sph 7.00 ~ +sph 6.00D). Amblyopia was found in 48.4% of the patients, DVD in 12.7%, IOOA in 11.3%, and manifest latent nystagmus in 6.0%. A binocular alignment within 10 PD was achieved in 73.9% and 57.9% at the 2nd and 4th post-operative year respectively.

Conclusions: The surgical outcome of bimedial rectus muscle recession in infantile esotropia was satisfactory in 74%, and 58% of the patients at the 2nd and 4th post-operative year respectively.
