Official title
Clinical Correlation Between Medial Rectus Tendon Width and Surgical Dose Response in Commitant Esotropic Patients Undergoing Medical Rectus Recession
Overview
This study aims to investigate the clinical correlation between medial rectus tendon width and surgical dose response in esotropic patients undergoing medical rectus recession
Detailed description
Esotropia is a type of strabismus where one or both eyes turn inward(1).Medial rectus tendon width is horizontal thickness of the tendon of the medial rectus muscle, one of the extraocular muscles.Medial rectus recession is a standard surgical treatment for esotropia involving weakening the medial rectus muscle by repositioning it posteriorly(2).Surgical Dose Response describes how much eye alignment in prism diopters is achieved per millimeter of muscle recession.
Studies on medial rectus resection revealed that higher medial rectus tendon width (MRTW) was associated with a larger surgical dose-response(3).Other studies revealed that the effect of lateral rectus recession in patients with intermittent exotropia was larger in cases with narrower lateral rectus tendon width (4,5).
The potential impact of medial rectus tendon width on the effectiveness of medial rectus recession had not been studied.
