superior rectus posterior fixation suture

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. The rectus posterior fixation suture is also called Faden, and the four rectus muscles can use this procedure. This procedure selectively reduces the function of the rectus muscle in its direction of action without affecting the inotropic and other gaze directions. Treatment of diseases: paralytic strabismus Indication Upper rectus posterior fixation suture is suitable for: DVD and mild paralytic oblique strabismus (such as the superior rectus abdominis during mild inferior rectus palsy, and the superior rectus abdominis when the inferior oblique muscle is paralyzed). Contraindications The superior rectus muscle has been treated after migration. Surgical procedure 1. Conjunctival incision, exposure of the rectus muscle with the upper or lower rectus muscle migration. 2. Separate the superior rectus muscle from the surrounding tissue by 15 mm, use the squint hook to lift the superior rectus muscle, and use the 5-0 non-absorbent suture (wire or nylon thread) to the superior rectus muscle at about 12 mm after the end. The abdomen was sutured and fixed on the sclera, or a needle was used to fix the superior rectus muscle central abdomen to the sclera. 3. It is also feasible to use the posterior fixation of the rectus muscle to fix the suture to enhance the surgical effect. 4. Stitch the conjunctiva. complication Vortex vein injury.
