Single Minimal Conjunctival Incision for Strabismus

August 3, 2023 updated by: Jaime Tejedor, Universidad Autonoma de Madrid

Single Minimal Conjunctival Incision for Rectus Muscles

The purpose of this investigation is to study the feasibility and inflammatory response of surgery for rectus muscles using a small single bulbar conjunctival incision posterior and parallel to the muscle insertion.

Patients requiring surgery of at least one rectus muscle with several diagnoses, operated under general or topical / sub-Tenon's anesthesia, who had no previous eye muscle surgery, will be recruited. Routinary clinical ophthalmological examination will be carried out. After applying a 5-0 PGA traction suture, a 3-4 mm single conjunctival incision posterior and parallel to the rectus muscle insertion will be done. A hang-back recession with 6-0 PGA suture will be carried out, and the conjunctiva closed by an 8-0 PGA single stitch. The main outcome measure will be duration of swelling and hemorrhage, and secondary outcome measure will be motor outcome at 2 months after surgery.

Detailed Description

Purpose/Background: To study the feasibility and inflammatory response of surgery for rectus muscles using a small single bulbar conjunctival incision posterior and parallel to the muscle insertion.

Methods: Patients requiring surgery of at least one rectus muscle with several diagnoses, operated under general or topical / sub-Tenon's anesthesia, who had no previous eye muscle surgery, are included. Routinary clinical ophthalmological examination is carried out. After applying a 5-0 PGA traction suture, a 3-4 mm single conjunctival incision posterior and parallel to the rectus muscle insertion will be done. A hang-back recession with 6-0 PGA suture will be carried out, and the conjunctiva closed by an 8-0 PGA single stitch. The main outcome measure is duration of swelling and hemorrhage, and secondary outcome measure is motor outcome at 2 months after surgery. Results are compared with retrospectively collected data of patients operated using limbal (n= 20) and fornix incision (n= 21) as a point of reference.
