Correction of infantile esotropia through a graded surgical procedure performed on three horizontal muscles can yield good long-term postoperative results, according to a study.
Glen A. Gole, MD, FRANZCO, and colleagues in Australia reviewed the records of 49 infants previously treated for infantile esotropia. The surgical procedure involved three horizontal muscle surgeries, including bilateral medial rectus resection and graded unilateral lateral rectus resection.
At week 1, there was a 93.9% cumulative surgical success rate that declined to 87.7% at 1 year, 79.9% at 2 years, 77.1% at years 3, 4 and 5, and 70.6% at 6 years follow-up.
The authors noted that the failure rate was independent of the patient’s preoperative deviation, and residual esotropia varied from 2% at 1 week to 17% at 6 years follow-up. Additionally, consecutive exotropia varied from 4% at 1 week to 12.4% at 6 years.
The study was published in Clinical & Experimental Ophthalmology.
