Summary

Horizontal strabismus, commonly known as inward or outward deviation of the eyes, is a frequent eye condition that may require surgical correction. Although the first surgery is often successful, some patients develop residual or recurrent eye misalignment and require a second operation (reoperation).

This study aims to identify the clinical and surgical factors that may increase the risk of undercorrection, overcorrection, or recurrence after the first surgery. It also evaluates the outcomes and success rate of repeat surgery in patients with horizontal strabismus.

Patients undergoing reoperation will receive a complete ophthalmological examination before surgery. The surgical plan will be individualized based on previous surgical history and current eye findings. All procedures will be performed under general anesthesia by the same surgeon. Participants will be followed for three months after surgery to assess eye alignment, movement, and possible complications.

The results of this study may help improve surgical planning and predict which patients are at higher risk of requiring additional surgery in the future.

Interventions

PROCEDURE

Horizontal Strabismus Reoperation

Horizontal strabismus reoperation is performed to correct residual or recurrent esotropia or exotropia following previous strabismus surgery. The surgical plan is individualized based on preoperative assessment and prior operative records. Previously operated muscles are explored when limited ocular motility, scarring, or suspected muscle slippage is present. In other cases, surgery may be performed on unoperated horizontal rectus muscles when appropriate. Intraoperative forced duction testing is conducted to assess muscle tightness, and scar tissue is released when indicated. All procedures are performed under general anesthesia by the same surgeon. Postoperative alignment and ocular motility are evaluated during follow-up visits.
