Purpose: To determine whether the changes in the ocular alignment following general anesthesia, maintained with two different inhalational anesthetic agents, sevoflurane and desflurane, can be used as a predictor for surgical outcomes in children with esotropia.

Methods: The authors obtained digital photographs of 42 children with esotropia; 21 patients underwent strabismus surgery with general inhalation anesthesia with sevoflurane (group A), 21 patients with inhalatory anesthesia with desflurane (Group B), as maintenance general anesthesia agents. For each patient, the corneal reflexes position were digitally measured and compared with the preoperative ocular deviation’s angle; the correlation with surgical outcome, one year after, was considered.

Results: The patients in both groups showed a decrease of the squint angle, or eye’s gap position after the induction of general anesthesia. In group B, this divergence was significantly higher than in group A (P<0.001). In both groups, there was a linear correlation between the preoperative angle and shortly after the induction of general anesthesia. Patients ranging a corneal reflexes position within 1 SD (15Δ) evidenced higher success of surgery (p<0.05) of patients>1 SD.

Conclusion: Changes in the ocular deviation with sevoflurane and desflurane, can be predictive for surgery outcome in children with esotropia. Furthermore, desflurane evidenced greater effects on the ocular deviation compared to sevoflurane, thus confirming to be the inhalational anesthetic of choice in strabismus surgery.
