| Abstract | ||
| Background: The most prevalent form of exotropia is intermittent exotropia. The effect of muscle recession can be predicted using the limbal insertion distance (LID). Objective: This study aimed to assess the treatment of intermittent exotropia (IXT) among both children as well as adults assembled on lateral rectus muscle LID using bilateral lateral rectus (LR) recession. Patients and methods: 46 participants ranged in age from 5 to 30 years old. Patients were separated into groups based on age. Group I included 35 patients (76.1%) with a mean age of 10.26 ± 4.11 years and group II included11 patients (23.9%) older than 17 years (23.55 ± 4.8). All patients were operated either bilateral or unilateral LR recession to alleviate exotropia under general anesthesia based on preoperative angle of deviation. Results: Mean dose-response differed significantly between groups which was significantly lower among patients older than 17 years. The mean dose-response was 4.73 and 4.4 in group I and group II respectively. Preoperative angle deviation, limbus insertion distance, and amount of recession all exhibited a strong positive significant correlation with the mean dosage response. Both preoperative angle deviation, LID, and amount of recession were found to exhibit a strong positive significant correlation with the mean dose-response. Conclusion: For intermittent exotropia treatment, preoperative lateral rectus muscle weakness, angle deviation, limbus insertion distance, and recession amount are all positively correlated with the mean dose-response in both eyes and in one eye separately. | ||
