OBJECTIVE To describe the effect of graded unilateral vs bilateral lateral rectus resection in the treatment of residual or recurrent esotropia after maximal medial rectus muscle recession. METHODS Retrospective case series of children with residual or recurrent esotropia. All children underwent initial eye muscle surgery for angles of 40 to 60 prism diopters (medial rectus recession of 5.5-6...

purpose: to describe the clinical findings, preoperative radiologic findings and results of surgery in a patient with congenital bilateral hypoplasia of medial rectus muscle case report: a 50-year-old man presented with large angle incomitant horizontal deviation with marked deficit of adduction of both eyes. mri finding defined very thin medial rectus muscle. intraoperatively medial rectus mus...

Some patients with large-angle strabismus may refuse or may not meet the criteria for binocular surgical correction. A second option for these patients involves a monocular procedure, which can be performed under peribulbar anesthesia and offers certain advantages (1). Improved surgical outcomes for conventional procedures may enhance the effectiveness of monocular surgery. In theory, this enha...

The purpose of this comparative study was to evaluate a long-term efficacy of lateral rectus muscle resection in the affected eye of patients with Duane retraction syndrome (DRS) with esotropia and limited abduction and to compare it with bilateral medial rectus recessions. We reviewed and compared the data of the group A with 23 patients who underwent a recession-resection procedure and the gr...

BACKGROUND Etiology and date of palsy are two important parameters that affect the treatment protocol of sixth nerve palsies. This study evaluated the treatment protocols and outcomes of treatment in sixth nerve palsies. METHODS Thirty-four patients who had sixth nerve palsy were included. Botulinum toxin A (BTX) injection was performed on patients with acute sixth nerve palsy and paresis (BT...

AIMS To compare the postoperative surgical outcomes and the changes in deviation achieved per millimetre of recession in patients treated by graded unilateral medial rectus (UMR) or bilateral medial rectus (BMR) recession for small to large angle esotropia with a minimum follow-up of 6 months. METHODS In a retrospective, consecutive and interventional case series, 102 patients underwent UMR r...

Purpose To report a case of inferior rectus muscle hypoplasia with esotropia, which was treated successfully by resection and anterior transposition of the inferior oblique muscle. Observations A 1-year-old boy presented with esotropia. He had esotropia of 15-30° and intermittent left hypertropia. At the age of 3 years, the alternate prism cover test showed esotropia of 35Δ and left hypertrop...

INTRODUCTION In esotropia with larger angles > near than at distance, splitting of the medial rectus muscle has been suggested as a treatment option. Previous reports of bilateral medial rectus Y-splitting as a first intervention showed a reduction of the distance/near disparity with fewer side effects compared to posterior fixation surgery. We address whether a medial rectus Y-splitting as a s...

Acquired esotropia with high myopia may be associated with superotemporal eyeball prolapse from the muscle cone and the subsequent shift of extraocular muscles limits the success of the traditional recession-resection surgery. In this study, we report two patients diagnosed with myopic strabismus fixus with esodeviation >90 prism diopter. Marked axial elongation of globes was present in both th...

IMPORTANCE Bilateral medial rectus muscle recession and one lateral rectus muscle resection surgery for the correction of large-angle infantile esotropia may be associated with a favorable long-term motor outcome. A consecutive exotropic drift was encountered more commonly than a recurrent esotropic drift in the long run, especially in the smaller (50-69 prism diopters [Δ]) range of preoperativ...
