DEVICE FOR TREATING THE CASES OF RESTRICTIVE SQUINT ASSOCIATED WITH ENDOCRINE OPHTHALMOPATHY

摘要

FIELD: medicine.;SUBSTANCE: method involves forming access to direct muscle of vertical action and into retroequatorial space. The first stage involves elongating the inferior direct muscle by making incision in sclera being equal in width to tendinous muscle portion width in parallel and proximally with respect to its attachment to sclera. Sclera is exfoliated in distal direction cutting out 2-8 mm long trapezoid scleral flap making continuation of the tendinous muscle portion. The second stage is carried out when the patient is not satisfied with achieved eyes orthoposition in direct eye glance position and in the cases of double imaging arising in transferring glance upwards. Superior direct muscle being contralateral antagonist on the healthy eye, is attached to sclera with two crossover sutures 12-16 mm far from physiological place of its attachment in the zone located on the other side of the eyeball equator. Cut-out scleral flap is 1/3 times as thick as sclera. The scleral flap being cut out longer than 2 mm, its lateral edge is moved in distal direction by 1-3 mm to temporal side. Scleral sutures are placed with 1/3 of its thickness being caught and stitch length being 2-3 mm long.;EFFECT: increased eye movability; reduced the first and the second deviation; reduced vision axes mismatch in ill and healthy eye.;4 cl, 3 dwg
