Binocular single vision (BSV)

Introduction In this article I will try to summarise some of the definitions, tests and assessments performed in the strabismus clinic to assess patient binocular potential. This is a key feature of strabismus assessment, especially in adults, and it will...

The challenge of chorioretinal folds in virtual eye clinics

Chorioretinal or choroidal folds are parallel striations involving the retina, retinal pigment epithelium (RPE), Bruch’s membrane, and inner choroid [1]. They can arise from compressive stress on these layers, and their presence often serves as a diagnostic marker for underlying...

Potential mechanism of over / under actions of inferior oblique muscles

In this paper, the authors hypothesise that fusional vergence adaptation, in patients who can fuse in at least some gaze positions, can cause curvature of the non-fixing eye movement paths of patients with apparent overaction or under action of the...

Adaptive optics imaging: resolving single cells in the living eye

The human retina is unique in the central nervous system (CNS) in that it can be directly visualised non-invasively. Technological advances of several imaging modalities, including optical coherence tomography (OCT), multichannel scanning laser ophthalmoscopy (SLO) and fundus photography, have afforded...

Review of bupivacaine use in treatment of strabismus

This review aimed to assess the applications of bupivacaine (B) in the non-surgical treatment of strabismus in human and animal studies. Animal studies show that singly-innervated fibres with low concentrations of mitochondria and developed sarcoplasmic reticulum are more affected by...

IO belly transposition surgery

The authors evaluated inferior oblique (IO) muscle belly transposition to correct mild to moderate IO overaction with small primary position hypertropia. They reviewed 10 patients aged 6-35 years (mean 18.6 years). Aetiologies were mild unilateral superior oblique (SO) palsy for...

Management of squint with near-distance angle disparity

These are a group of strabismus disorders where the angle of misalignment is different between near and distance. The focus of this article will be on the patients where the angle for near exceeds the distance angle by more than...

How good does my vision have to be to drive this thing? Visual standards for various occupations

We can all picture that moment in clinic: you are about to tell someone that they’re no longer legally able to drive, ready to deploy our ‘breaking bad news’ techniques. For some patients this may have been expected, or they...

Management of restrictive diplopia after ptergium surgery

This single centre retrospective case series included 15 patients with restrictive diplopia after ptergium excision. The mean time from surgery to diplopia was six months and all patients had a moderate limitation of abduction in the operated eye causing an...

Comparison of degradation of stereoacuity with reduced visual input

The aim of this study was to investigate the differing extents to which stereo thresholds obtained with Frisby, TNO, Lang Stereopad and ASTEROID stereo tests are affected by changes in visual input in adults. Bangerter foils (0.2 and 0.4) were...

Amblyopia treatment review

This review paper summarises the main causes and neural mechanisms that characterise amblyopia. The authors analysed neuroanatomical, neurophysiological and electrophysiological studies in the literature to better understand actual treatment regimens and evaluate new therapeutic possibilities. They considered causes of strabismus,...

IO overaction surgery

This study aimed to compare the effectiveness of two surgical methods on the correction of inferior oblique overaction (IOOA). This was a retrospective study of 99 eyes of 56 patients; 47 myectomy and 52 anterior transposition procedures. Mean age was...
