METHOD FOR DETERMINING DIFFERENTIAL INDICATIONS TO REPEATED OPERATIONS FOR STRABISMUS Russian patent published in 2011 - IPC A61F9/00 

FIELD: medicine.

SUBSTANCE: outer border of the limb is determined, as well as a recession previously done on the direct extraocular muscle, insertion of this muscle, its distance from the limb in case of eye deviation toward recessed muscle by means of optical coherence tomography, as well as direction of eye deviation toward recessed muscle and the angle of deviation of Girshberg. If the recessed muscle is inserted at a distance of 8.0 mm or less from the limb, the eye is declined in the direction of the muscle, and the angle of deviation of Girshberg is up to 10°, the re-recession is indicated. If the recessed muscle is inserted at a distance of 8.0 mm or less from the limb, the eye is declined in the direction of this muscle and the angle of deviation of Girshberg is greater than 10°, the re-recession and additional resection of the muscle-antagonist are indicated. If the eye is declined in the opposite direction from the recessed muscle, while the angle of deviation of Girshberg is up to 10°, irrespective of its distance from the limb an anterior transposition of this muscle is indicated. If the eye is declined in the direction opposite the recessed muscle, while the angle of deviation of Girshberg is more than 10°, irrespective of its distance from the limb an anterior transposition of this muscle and additional resection are indicated.

EFFECT: method enables to expand the arsenal of existing methods of determining indications for repeated operations for strabismus, reduce injury during surgical interventions.
