Изменение угла косоглазия у пациентов с эссенциальной младенческой эзотропией в условиях общей анестезии и его влияние на выбор оптимального хирургического протокола

Abstract

Purpose. To evaluate the dynamics of esodeviation in patients with essential infantile esotropia in the awake state and under general anesthesia in order to determine the optimal surgical protocol. Material and methods. A study was made of changes in the angle of strabismus and traction test in 15 patients aged 4 to 18 months under physiological conditions and under general anesthesia. Results. Four patients were diagnosed with orthotropia, a negative traction test, so the actual dose of the drug was reduced. In three patients with cross-fixation syndrome, the magnitude of esotropia in anesthesia decreased, a positive traction test was recorded, and they required the maximum dose of Botox. In the remaining patients, the magnitude of esodeviation ranged from 3 to 8°, the traction test was negative, the planned dose of the drug did not require correction. Conclusions. The dynamics of the strabismus angle under general anesthesia in patients with essential infantile esotropia is a fundamental factor determining the choice of the optimal dosage of Botox for chemodenervation of m. rectus medialis.
