IMPORTANCE Recognition of sagging eye syndrome (SES) as the cause of chronic or acute acquired diplopia may avert neurologic evaluation and imaging in most cases. OBJECTIVES To determine whether SES results from inferior shift of lateral rectus (LR) extraocular muscle (EOM) pulleys and to investigate anatomic correlates of strabismus in SES. DESIGN AND SETTING We used magnetic resonance ima...

Previous studies have shown that low amplitude/high frequency mechanical vibration applied to the human eye muscles results in the illusory movement of a luminous spot fixated in total darkness. The aim of the present study was to investigate whether a vibration-induced motor response also occurs in eye muscles, and to check whether the visual illusions actually result from the proprioceptors b...

Address for Correspondence: Edward Ridyard, 9 The Meadows, Rainhill, Prescot, L35 0PQ, UK. E-Mail: [email protected] Foundation Year 2 doctor, Oxford University Hospitals, Prescot, UK. Background: The extraocular muscles (EOMs) bring about eye movement and studies exist which measure EOM length, cross-sectional diameter and volume. Knowledge of the normal values is crucial for deter...

purpose: to report a patient with exotropia due to medial rectus muscle entrapment as a complication of endoscopic dacryocystorhinostomy (edcr). case report: a 34-year-old female was referred with left exotropia 18 days after edcr for treatment of primary nasolacrimal duct obstruction. she had a large angle left exotropia in primary position as well as complete limitation of adduction and parti...

OBJECTIVE The objective of this study was to find the most appropriate, accurate, and convenient muscle parameter that can be used as a substitute for volume in monitoring the effectiveness of therapy of patients with Graves' ophthalmopathy. SUBJECTS AND METHODS The four rectus muscles in 110 orbits (35 patients and 20 control subjects) were evaluated with MR imaging. The diameter at the larg...

BACKGROUND This study investigates the clinical features of strabismus in patients with general fibrosis syndrome (GFS) and the results of surgery performed on such patients. METHODS We conducted a retrospective review of patients with GFS who visited our clinic at Chang Gung Memorial Hospital between 1 August 1992 and 31 January 2002. After evaluating the family histories of 9 patients with ...

PURPOSE It has been proposed that the lateral rectus (LR), like many skeletal and craniofacial muscles, comprises multiple neuromuscular compartments subserving different physiological functions. To explore the anatomic potential of compartmentalization in all four rectus extraocular muscles (EOMs), evidence was sought of possible regional selectivity in intramuscular innervation of all rectus ...

PURPOSE To evaluate the efficiency of mitomycin C (MMC) in limiting the postoperative inflammatory response and scarring after strabismus surgery. METHODS A prospective, two-stage, masked, controlled trial was conducted. In the first stage, the inflammatory response at the extraocular muscle reattachment site was increased after inferior rectus recession in eight rabbits. In the second stage,...

Introduction: Rectus sheath hematoma (RSH) is an uncommon cause of acute abdominal pain that often misinterpreted. Only about 2% patients who present with display this condition. Damage to the superior or inferior epigastric arteries their branches, as well direct rupture rectus abdominis muscle, causes bleeding into sheath. In hospitalized COVID-19 patients, anticoagulant prophylaxis heparin h...
