Characteristics of age-related distance esotropia

The primary aim of this study was to describe clinical characteristics and natural history of age-related distance esotropia (ARDET) within an adult cohort over a 20-year period. This was a retrospective review of 73 patients from 751 with adult onset...

Changes in corneal endothelial layer after strabismus surgery

The purpose of this study was to investigate the changes in the corneal endothelial layer by specular microscopy after surgery in patients with horizontal and oblique strabismus. Eighty-three eyes of 56 patients were evaluated prospectively. There were three subgroups: one...

Outcomes of horizontal muscle transplantation

The authors propose the technique of transplantation of the resected muscle segment to the previously recessed muscle for correction of residual / recurrent strabismus in order to restrict surgery to one eye and avoid large recession of previously recessed rectus...

Medial rectus spontaneous reattachment after surgery

The authors report necropsy findings following free tenotomy of the medial rectus (MR) muscle in six postnatal monkeys. Bilateral MR tenotomy was performed producing alternating exotropia of 30-70 degrees with no adduction beyond primary position. Over follow-up, all showed reduction...

Surgical management of high myopia strabismus

This is a small case series of three patients with unilateral or bilateral high myopia with exotropia and hypotropia. Surgery involved nasal loop myopexy between the medial and superior recti muscles with or without lateral rectus recession and / or...

RR versus PR in children with intermittent exotropia

This is a retrospective study of 186 children who underwent resection-recession (RR) or plication-recession (PR) for intermittent exotropia between January 2008 and July 2016, from Seoul Korea, with a minimum follow-up of two years. Standard fornix based approach was used...

Medial rectus anatomy in exotropia

This study investigates the differences between extraocular muscles in patients with intermittent exotropia and normal controls regarding muscle fibre arrangement and diameter, and distribution and activation of satellite cells. Fifteen patients were recruited having medial rectus resection surgery. Resection sections...

Improving distance stereopsis in intermittent exotropia with training

This study compared the control ability of patients with stereopsis and analysed the influencing factors of the improvement of distance stereopsis in children with intermittent exotropia. Seventy-eight children were recruited: 33 male, 45 female with mean age of 8.4 ±2.72...

Intermittent exotropia with a positive Bielchowsky head-tilt test

This is a retrospective study from Korea, of 118 patients’ charts with intermittent exotropia (IXT) and divided into two groups; 50 patients showed positive Bielchowsky head tilt test (BHTT) and 68 with negative BHTT. Significant differences (p<0.05) in the parameters...

Lost muscle surgery

The authors present the results of transposition surgery without concomitant lateral rectus weakening in a retrospective review of five cases. Surgery was for large exotropia and marked limitation of adduction after surgical loss of the medial rectus muscle. Mean age...

Outcome of three to four muscle surgery for XT

This study evaluates the short-term outcomes of surgery involving three or four horizontal rectus muscles in patients with exotropia >40 prism dioptres. The authors evaluate the role of adjustable sutures and identify prognostic factors influencing surgical outcome. They assess the...
