FIELD: medicine.SUBSTANCE: invention relates to ophthalmosurgery, and may be used for treating atypical forms of squinting. What is involved is a limb incision of a conjunctiva in a medial quadrant; a medial rectus muscle is separated from anterior ciliary arteries and fascia; a scleral blade is used to cut out a flap 4-5 mm long of scleral surface layers from an attachment point of an extraocular muscle (EOM) to an equator, without dissection; it is followed by a limb incision of the conjunctiva in a lower quadrant; the same procedure is used to cut out a flap of a lower rectus muscle 3-4 mm long from an attachment point of the EOM to an equator; it is followed by a limb incision of the conjunctiva in a superolateral quadrant; a middle long one-third of the lateral rectus muscle is sutures at 10-12 mm from its attachment point, and the latter is transposed upwards at 8-9 mm towards the upper rectus muscle along the equator and displaced by 5-7 mm to the limb and fixed to the sclera; the same technique is used to take the middle long one-third of the upper rectus muscle in forceps, sutured at 7-8 mm from its attachment point, , and the latter is transposed horizontally at 4-5 mm towards the external rectus muscle along the equator; the lateral rectus and upper rectus muscles are sutured together and displaced at 5-7 mm to the limb and fixed to the sclera.EFFECT: method provides higher surgical effectiveness and stability.5 dwg, 3 ex |
