Results of single muscle advancement surgery

The aim of this study was to determine quantitatively the efficacy of medial and lateral rectus muscle advancement in consecutive exotropia and esotropia. The authors analysed the relationship between the change in muscle position and the change in visual angle...

Effective contrast ratio as a measure of binocular visual perception

The authors used a binocular phase combination paradigm to quantitatively evaluate and compare the binocular visual perception of normal individuals and patients with different types of strabismus to understand the binocular visual perception of patients with strabismus and evaluate whether...

Reporting the development and pilot use of fixable surgical instruments

This study reports the development of instruments to substitute traction sutures during strabismus surgery and to act in place of surgical assistance. Three types of instruments were developed: (1) fixable multi-functional forceps; (2) fixable muscle hook; and (3) fixable retractor....

Long-term outcomes of recess / resect for sensory XT

The purpose of this study was to evaluate relationships between initial and long-term outcome of unilateral recess / resect surgery in adult sensory exotropia, factors associated with long-term outcome, exotropia drift and time to failure follow-up surgery. This was a...

Myasthenia Gravis Masquerading as a Third Cranial Nerve Palsy

A 65-year-old man presented with a week’s history of binocular diplopia (in all directions of gaze) and a right partial ptosis. He was systemically well. His past medical history was unremarkable except for vitiligo. At presentation acuity was 6/6 bilaterally....

Refractive surgery for anisometropic amblyopia

The authors report the outcomes of refractive surgery with phakic intraocular lens (PIOL) implant for management of anisometropic amblyopia in children intolerant to conventional therapy. This was a retrospective study of 71 eyes of 71 patients of which 58 were...

Amblyopia treatment

This study was conducted to assess practice preferences in the management of amblyopia among paediatric ophthalmologists. A close-ended multiple choice questionnaire consisting of 10 questions was circulated to 113 paediatric ophthalmologists and fellows of which 74 completed the questionnaire. Seventy-six...

Three muscle surgery results for ET

There is limited information in the literature on the outcomes of three muscle surgery. The authors aimed to evaluate the medium term motor outcomes of three horizontal muscle surgery in 18 patients with large angle infantile esotropia of at least...

Surgical outcome reporting for exotropic DRS

The authors report the surgical outcomes of patients with exotropic Duane’s retraction syndrome (DRS) in a retrospective study of 73 patients; 67 unilateral cases. Patients had a mean age at surgery of 14.11 years (range 2-33). The left eye was...

Immediate postop alignment differences between adult and childhood ET

The purpose of this study was to investigate the immediate postoperative alignment among patients undergoing successful surgery for esotropia and to determine whether there are any differences between children and adults. This was a retrospective case review of 544 cases;...

Strabismus and binocular summation

The authors conducted a pilot study to investigate the effect of visual noise or background complexity on binocular summation in patients with strabismus. A target embedded in pixel noise was used. The study involved performance of a task detecting a...

Improvements in balance and postural control after strabismus surgery

The authors sought to investigate the effect of surgical correction of strabismus on dynamic balance and postural stability. They recruited 27 children (15 female, 12 male) of which 17 were esotropia and 10 exotropia (including eight intermittent types), aged 7–12...
