Comparison of the inferior oblique weakening by disinsertion or disinsertion-resection and tucking in the patient with infantile esotropia.

The effectiveness of disinsertion vs disinsertion-resection and tucking procedure of the inferior oblique muscle for infantile esotropia was studied. Preoperative muscle overaction scores were +3.2 +/- 0.6 and +3.3 +/- 0.48 for the two groups, respectively. Postoperatively, there was + 0.52 average score in five Group I cases, whereas there were none in Group 2. We conclude that the disinsertion-resection and tucking procedure is more effective than simple disinsertion.
