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...

Anatomical studies demonstrate selective compartmental innervation of most human extraocular muscles (EOMs), suggesting the potential for differential compartmental control. This was supported by magnetic resonance imaging (MRI) demonstrating differential lateral rectus (LR) compartmental contraction during ocular counterrolling, differential medial rectus (MR) compartmental contraction during ...

OBJECTIVE To assess donor-site morbidity and survival of the rectus abdominis muscle with an overlying skin graft after free tissue transfer to a medial femorotibial defect in dogs. STUDY DESIGN Experimental study. SAMPLE POPULATION Phase 1: 6 canine cadavers; phase 2: 7 adult mixed-breed dogs. METHODS Phase 1: The rectus abdominis muscle was removed from canine cadavers, muscular and vas...

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...

IMPORTANCE Extraocular muscle strengthening is a common treatment for strabismus. Plication is an alternative procedure for strengthening muscles with less tissue trauma than resection. OBJECTIVE To compare the surgical dose effect of plication with that of resection. DESIGN, SETTING, AND PARTICIPANTS Retrospective comparison of surgical outcomes in an academic pediatric ophthalmology and s...

A 76-year-old man with hypertension suddenly developed horizontal diplopia. Examination disclosed adduction deficit of left eye without dissociated abducting nystagmus and ocular tilt reaction (OTR) (video). The impaired adduction was similar for saccades, smooth pursuit, the vestibulo-ocular reflex, and convergence. Vertical eye movements were normal. Diffusion-weighted MRI demonstrated a circ...

INTRODUCTION We report on a case of isolated metastatic breast cancer to the medial rectus muscle. This entity is exceedingly rare. CASE A 44-year-old female with a history of breast cancer presented with unilateral maxillary symptoms and was treated for sinusitis. Over time, she developed ocular pain, diplopia, blurred vision and eventually complete adduction deficit. RESULTS T1-weighted m...

PURPOSE To compare unilateral versus bilateral surgical treatment of esotropia associated with high myopia. METHODS This retrospective study comprised patients who underwent surgery for esotropia with high myopia performed by the first author (Y.M.) between 2003 and 2008. Surgical results and complications were compared between patients who underwent unilateral versus bilateral surgery. RES...
