Bilateral versus unilateral recession outcomes for intermittent exotropia

The aim of this study was to compare surgical motor and sensory outcomes of unilateral versus bilateral lateral rectus recessions in children with small angle intermittent exotropia. This was a retrospective study of 55 patients; 28 bilateral and 27 unilateral...

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...

Early postoperative angle for prediction of surgical success for exotropia

In this study, the authors assessed the relationship between the initial postoperative deviation and surgical outcomes in adult exotropia undergoing unilateral lateral rectus recession with medial rectus resection. The study included 93 patients (51 female); 26 with residual exo, 53...

Types of nystagmus and associations in a large international database for nystagmus

The authors aimed to characterise a large international cohort of children with nystagmus. Data were taken from a prospective database which was started in 2010. Up to 2020, this contained 1774 patients with nystagmus from 38 US states and 30...

Differences in strabismus surgery outcomes in preterm vs full-time birth infants

This study aimed to analyse motor and sensory outcomes of strabismus surgery in 70 preterm (group 1) and 242 full-term (group 2) infants. Group 1 mean gestational age and birth weight were 31.25 ±2.51 weeks and 1562.70 ±412.82g. Pre and...

Augmented surgery with BTA for large angle strabismus correction

This retrospective study reports the results of botulinum toxin A (BTA) augmented bilateral recession or monocular recession / resection (RR) for patients with large angle strabismus. Twenty-four patients were recruited: 10 female, mean age 9.2 ±13.6 years, 20 esotropia and...

Choice and definitions of surgical outcomes for intermittent exotropia

This review was conducted to address a number of questions: (1) define successful surgical outcome; (2) criteria for successful alignment, (3) consideration of aetiology when deciding surgery, and (4) are visual acuity, fusion and stereoacuity routinely investigated as surgical outcomes?...

Prism fusional vergence measures for Risley vs prism bar measurements

This study sought to investigate the agreement between the phoropter Risley and the prism bar prism fusional vergence amplitudes among a normal sample of Ghanaian children aged 8–17 years. This was a school-based study of 2300 children. Of 2300, 116...

Anisometropia following cataract surgery and its non-surgical treatment

The desired result of cataract surgery is improved visual acuity without the use of spectacles. In practice most patients following initial cataract extraction are likely to be symptomatic of anisometropia giving rise to prismatic effects (anisophoria) and unequal retinal image...

An Introduction to: RCOphth's Microsurgery Course

For foundation doctors and medical students with a keen interest on becoming ophthalmologists, the RCOphth Microsurgery Introduction Course stands as a gateway to introducing doctors to the intricacies of microsurgery.

Key research and practical information to inform INS care

This ‘tutorial’ format paper aims to translate key research findings and conclusions into practical terms, discuss their clinical utility and introduce a new clinical method that accurately measures the static visual deficits in infantile nystagmus (INS), predicts the improvements that...

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...
