Link between compression of anterior visual pathway structures and visual deficit

The compression of anterior visual pathway (AVP) structures can be observed on neuroimaging. It is not clear whether or not this compression results in damage to these structures. The authors present a single centre retrospective case record review over the...

Choroidal vascularity in NAION

The authors present a cross-sectional, non-interventional study of healthy volunteers and those with non-arteritic anterior ischaemic optic neuropathy (NAION) recruited over a six-month period at a single site. NAION is the most common cause of acute optic neuropathy over the...

Preoperative anxiety levels and pain during cataract surgery

Increased anxiety has been shown to be associated with greater pain in a number of procedures. In this observational, non-interventional study, the authors sought to evaluate the correlation between pain with phacoemulsification surgery (under topical and intracameral local anaesthesia) and...

Smartphone use and its effects on eyes

Longitudinal pilot study on 12 young healthy adults comparing effects of smartphone use over a 60-minute period. Reading conditions and smartphone use was standardised for all participants. Ocular symptoms, tear function and binocular vision were assessed before and after each...

Global prevalence of strabismus

With a need for relevant information to design plans for screening, early diagnosis and timely management, the aim of this study was to present a systematic review of the sources to provide an estimate of the global prevalence of strabismus...

A novel presentation of optic disc oedema with syphilis

Optic disc oedema (ODE) due to syphilis without visual compromise has been primarily attributed to papilloedema from raised intracranial pressure or optic perineuritis from optic nerve sheath inflammation. These terms were proposed before magnetic resonance imaging (MRI) was largely available....

Duane’s retraction syndrome (DRS)

The authors aimed to review all cases of DRS presenting to a tertiary paediatric eye clinic in South Africa during a 20-year period. This was a retrospective study in Cape Town involving 120 patents (80 mixed race, 24 black and...

Ozurdex in epiretinal membrane surgery

This was a prospective multicentre pilot study, looking at the effect of Ozurdex on visual acuity (VA) and central retinal thickness (CRT) in patients undergoing surgery for epiretinal membrane (ERM). Twelve eyes of 12 patients were included in the study....

A case study of posterior globe flattening in idiopathic intracranial hypertension

The authors present a single case of posterior globe flattening without papilloedema in idiopathic intracranial hypertension. The case was a 64-year-old woman with a one-year history of transient visual loss in her left eye only. Visual acuity was 20/20 in...

Topical nonsteroidal ant-inflammatory drugs (NSAIDs) in patients undergoing cataract surgery

Inflammation is a major risk factor for the development of cystoid macular oedema (CMO) after cataract surgery, leading to breakdown of the blood-retina barrier. There is a correlation between severity of CMO and level of postoperative inflammation. Laser flare meter...

Referrals to neuro-ophthalmology

The authors present the findings of a retrospective records review of 300 new patients at a single tertiary neuro-ophthalmology clinic by two ophthalmologists. The case selection was taken from 45 randomly selected days over a four-year period. The authors reported...

Ultra-widefield fundus autofluorescence

The authors assessed the ease and utility of ultra-widefield fundus autofluorescence (UWF-FAF) in detecting suspected inherited retinal disease in children who were difficult to examine. They aimed to assess the sensitivity of UWF-FAF and UWF-CF (colour fundus) photography and clinical...
