Rectus muscle recession and resection without scleral sutures
1Cullen Eye Institute, Baylor College of Medicine, Texas Children's Hospital, Houston 77030, USA.
Summary
This study presents a novel suture technique for strabismus surgery, enabling safe rectus muscle recession and resection in patients with thin sclera. The method avoids scleral sutures, minimizing perforation risk and achieving excellent ocular surface appearance.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Strabismus Surgery
Background:
- Strabismus surgery carries a risk of scleral perforation, particularly in patients with thin sclera.
- Traditional rectus muscle surgery involves scleral sutures, which can be hazardous in susceptible individuals.
Purpose of the Study:
- To introduce a novel surgical technique for rectus muscle recession and resection that eliminates the risk of scleral perforation.
- To enable predictable and secure muscle repositioning without direct scleral suturing.
Main Methods:
- A double-arm suture technique was employed in three patients with thin sclera undergoing strabismus surgery.
- The technique avoids direct placement of sutures into the sclera.
- Procedures included bilateral lateral rectus resections, a unilateral recess/resect operation, and bilateral lateral rectus recessions.
Main Results:
- All three patients achieved successful postoperative alignment within 15 prism diopters (PD) of orthotropia.
- No instances of slipped or lost muscles were observed at the 2-month postoperative examination.
- Excellent ocular surface appearance was noted in all cases.
Conclusions:
- Predictable and secure rectus muscle recession and resection can be achieved without scleral sutures.
- This technique is a viable alternative for patients with thin sclera where scleral suturing poses a significant risk.
