Vision screening standards for fitness to drive

Most countries require that vision meets a pre-defined standard in order to be legally permitted to drive, but these standards vary widely. The primary method by which vision is assessed to determine suitability for driving is by measuring visual acuity...

Glasgow eye department continues to disrupt ocular simulation training through novel DRV system - the first of many?

Ongoing technological developments are enabling continuous progress to be made across all aspects of medical simulation training. This is particularly true within the field of ophthalmology, where surgical training advancements have enabled the role of simulation to expand dramatically over...

Refraction planning in cataract: avoid creating an unhappy patient

“It is much more important to know what sort of a patient has a disease than what sort of a disease a patient has.” William Osler The focus of this paper is the prevention of an unhappy patient following cataract...

Narrative literature review for intermittent exotropia

This is a narrative literature review on prevalence, terminology, risk factors, natural history and clinical characteristics for intermittent exotropia. A Medline search was conducted with no date restrictions up to September 2020 and collating English language studies. Prevalence was reported...

How to pass the Refraction Certificate

Unfortunately, I had the pleasure of getting to know this exam intimately. With adequate preparation this does not have to be the case for most people. The exam has recently changed to consist of 10 OSCE style stations (previously 12)....

Comparison of bilateral lateral and unilateral recession resection for IXT

This is a retrospective review study of patients between the ages of three and 15 years old with the basic type of intermittent exotropia (IXT) who had strabismus surgery between January 2003 to September 2009. There were 85 patients included...

Association of asthenopia and heterophoria

Heterophoria varies over time and asthenopic symptoms may be greater when the heterophoria is larger. Thus a close intra-individual correlation may exist between heterophoria and discomfort during reading. The authors investigated the variability of both parameters in 20 individuals who...

Association between colour vision impairment and amyotrophic lateral sclerosis (ALS)

The purpose of this study is to test the hypothesis that colour vision impairment is associated with amyotrophic lateral sclerosis (ALS). Abnormalities of the inner and intermediate retinal structures in patients with ALS have been described using optical coherence tomography...

AC/A correlates

Three groups of subjects were included in this study. Group 1 had typically developing children from five to nine years with heterophoria less than 6PD. Group 2 had 19 children aged five to nine years with intermittent distance exotropia. Group...

An interesting presentation of ruptured anterior communicating artery aneurysm with acute monocular vision loss

The authors report an interesting case of a 60-year-old man presenting with acute monocular vision loss accompanied by periorbital pain as an unusual presentation of subarachnoid haemorrhage (SAH) from ruptured anterior communicating artery aneurysm. The patient did not present with...

Can the angle of origin of the ophthalmic artery predict embolic trajectory?

A retrospective, comparative case-control study was used to test the hypothesis that a risk factor for retinal versus cerebral infarct is the angular origin of the ophthalmic artery from the internal carotid artery. The study compared one group (n=28) who...
