Preoperative, early postoperative (within 1 week of surgery), and late postoperative (at least 6 months after surgery) IOOA scores (on a scale of 0-4) were analyzed.
A t-test was used to compare pre- and postoperative IOOA and the initial and final postoperative follow-up results.
The patients' mean preoperative IOOA grade was 2.55 [+ or -] 0.75.
IOOA is an incomitant vertical deviation characterized by eye elevation caused by adduction.
Both primary and secondary IOOA have been successfully treated with myectomy, recession and transposition procedures for many years.
The mean follow-up duration was 15 months; the mean pre-and postoperative IOOA severity was 2.88 [+ or -] 0.75 and 0.16 [+ or -] 0.38, respectively.
Recession is another surgical procedure used to treat IOOA. In a study by Rajavi et al.
