Superior Rectus Recession Surgery

The clinical features of the discrete vertical strabismus (DVD): 1 is covered by the eye, the degree of rotation of the eyes is different, and the oblique viewing angle is unstable. 2 often combined with recessive nystagmus. 3 combined horizontal strabismus, considered congenital internal oblique. More than 4 concurrent amblyopia. 5 About 1/4 of patients have abnormal head position or ocular torticollis. Six cases were accompanied by vertical muscle paralysis or hyperfunction (the following oblique muscle function is more common). Corrective DVDs often use bilateral intraocular rectus resurfacing, posterior fixation suture, or a combination of both, and can also be used for rectus suspension surgery. Those with different degrees of eye-turning can do the up-and-coming eyes first, and then perform another eye surgery. Treating diseases: strabismus Indication Upper maxillary migration is applied to: Separate vertical deflection (DVD) and inferior rectus paralysis. Contraindications The superior rectus muscle has been treated as a post-migration. Surgical procedure 1. Make a limbus trapezoidal conjunctival incision and separate the connection between the bulbar conjunctiva and the fascia. 2. Cut a small hole in the fascia on both sides of the superior rectus muscle attachment point, vertically separate until the sclera is fully exposed, and separate the sclera from the fascia along the superior rectus muscle. 3. From one side of the small hole into the strabismus hook, with the sclera sliding under the superior rectus muscle, to reach the opposite side of the hole. If the top of the squint hook is blocked by the fascia, it is separated. So from left to right, from right to left, repeated 2 to 3 times, can hook the entire superior rectus muscle. 4. Separate the fascia and intermuscular membrane along the two sides of the superior rectus muscle to fully expose the superior rectus muscle. 5. On both sides of the upper rectus muscle attachment point 1.5mm, use 6-0 absorbable suture or nylon thread as the collar preset suture, and cut the upper rectus muscle from the attachment point. 6. Measure the distance after migration on the sclera and fix the preset suture to the new attachment point. 7. Observe the eye position and eye muscle movements and adjust if necessary. 8. Stitch the conjunctiva.
