Fusional vergence measurement

This paper reports a systematic review to address two objectives: 1, to compare the normative values of tests measuring fusional vergence; 2, to investigate sources of heterogeneity of prism accuracy. The review was conducted according to PRISMA guidelines with a...

Brexit, for richer, for poorer: prospects for post-withdrawal Britain

The people of the United Kingdom voted by 52% to 48% to leave the European Union (EU) in June 2016, a referendum decision intended by a slim majority to restore national self-determination and achieve what many believed to be a...

The future of SLT?

For Feb/Mar 2024, we are looking at a recently released laser machine to perform direct SLT – selective laser trabeculoplasty (DSLT). Although SLT is well known, DSLT is sufficiently novel that a brief description is a good place to start....

A comparison of light sources in retinal imaging

Before starting to talk about the light sources present in retinal imaging, it is necessary to start from the base: the light. Light is an electromagnetic wave whose smallest part is the photon (or quantum of light). A high frequency...

Surgical effect of limited membrane dissection

Strabismus surgery was performed with minimal dissection of Tenons sheath and minimal tissue manipulation compared to conventional methods for patients with pure horizontal strabismus – to evaluate the effect on surgical outcomes. The study included 54 patients; 52% female. Mean...

Static subjective visual vertical (SVV) in the normal visual system

Graviception is the perception of a persons’ orientation relative to gravitational force. This can be measured by means of subjective verticals, which can be divided into three tests: subjective visual vertical (SVV), subjective postural vertical (SPV) and subjective haptic vertical...

Amniotic membrane efficacy

This prospective randomised study evaluated the effect of amniotic membrane (AM) in reducing inflammation, fibrosis, adhesion formation and ocular movement restrictions following strabismus surgery. This study used 22 rabbits: all with superior rectus recession in both eyes with AM placed...

Brn3b neuroprotective effect in rat glaucoma model

An adeno-associated virus-directed overexpression of the Brn3b protein in hypothesised to confer neuroprotective effects in this paper. This is ultimately tested in a well-accepted rat glaucoma model (Morrison’s model: saline injection into episcleral veins of rat eyes with a force...

Abducens nerve palsy following surgical correction of craniosynostosis

The authors present two cases of unilateral abducens palsy secondary to a recent trans-sutural distraction osteogenesis (TSuDO) operation for craniosynostosis. The basic principle of the TSuDO procedure is described as dissection and distraction of the prematurely fused sutures. This complication...

Clinical predictors of proliferative sickle cell retinopathy

Sickle Cell Disease (SCD) is an inherited disorder resulting in production of Haemoglobin S (HbS), which aggregates in conditions of hypoxia, acidosis or hyperosmolarity. This leads to vascular stasis, thrombosis and ischaemia. The authors present a cross-sectional study (45 consecutive...

Features and outcomes of pulled-in-two syndrome

Pulled-in-two (PIT) syndrome is a sudden rupture of the extraocular muscle during strabismus surgery, typically with minimal tension intraoperatively without excessive force. This is a rare occurrence and this study reports cases from a single centre over a seven-year period....
