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...

Comparison of bupivacaine injection vs. mini-tenotomy for small angle deviations

Bupivacaine hydrochloride is an aminoacyltype local anaesthetic. Injection into extraocular muscles elicits a myotoxic response destroying striated muscle fibres but sparing satellite cells, nerves and vessels. Preserved satellite cells proliferate to form new muscle fibres, causing muscle hypertrophy and greater...

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...

Exotropia symptoms

The aim of this study was to evaluate clinical preoperative symptoms and changes to these postoperatively in patients with exotropia. A non-validated questionnaire with 15 questions was used: three subscales including stereopsis (five questions), ocular fatigue (five questions) and cosmetic...

Q&A: Mr Goel and Mr Loomba on alcohol delamination and phototherapeutic keratectomy (PTK) for the treatment of recurrent corneal erosion syndrome

Recurrent corneal erosion syndrome is a common, recurrent condition caused by abnormal epithelial adhesion to the underlying basal lamina. Spontaneous breakdown of the corneal epithelium can lead to the sudden onset of ocular pain, blurred vision, tearing and photophobia, typically...

Rebamipide 2% for dry eye

Rebamipide is a quinolinone derivative that has been found to increase mucin production and the number of conjunctival goblet cells. A previous phase two study has shown rebamipide 2% to be better than placebo in improving the ocular surface and...

Associations of esotropia with shunts

This study explored the characteristics and outcomes of children with esotropia and ventriculo-peritoneal (VP) shunt placement due to hydrocephalus. The authors conducted a retrospective study of 16 patients (nine female, seven male) aged three months to 5.6 years (mean 17...

High prevalence of strabismus and variable surgical success in children with developmental delay

On the basis of lack of consensus for the treatment of strabismus in children with developmental delay, the authors reviewed the literature to provide information on the topic and present results from their clinical experience. From the review, they include...

Measuring IPD with PlusoptiX

The authors evaluated the accuracy of the PlusoptiX A04 for measuring pupillary distance as compared to measurements taken by a trained optician. This retrospective review included 256 children who had undilated PA04 screening and had pupil distance measurement done by...

Changing surgery trends from 2009–2020

This paper reports a review of the number and type of surgeries over one decade in a Portuguese hospital. This was a retrospective review of 2050 surgeries. About 70% were strabismus surgery and the remainder included anterior segment and retinopathy...

Long-term motor and sensory outcomes after surgery for high AC/A ratio esotropia

This study reports the long-term ocular alignment and sensory outcomes after medial rectus recession for high accommodative convergence to accommodation (AC/A) ratio esotropia with a minimum postoperative follow-up of five years. The study included 34 patients (16 male); 31 had...
