Grading of ocular inflammation in uveitis: an overview

Anterior uveitis is the commonest form of uveitis, which can lead to severe morbidity if not treated appropriately [1]. Data from general ophthalmology practices suggest around 90% of uveitis encountered by comprehensive ophthalmologists is anterior uveitis [2]. Intermediate (vitreous), posterior...

OCT in microtropia

The aim of this study was to assess whether OCT could be useful in detecting and documenting fixation in children with microtropia. The study used spectral domain OCT (Cirrus) in 15 patients (10 female, five male) and 10 control eyes....

Van Herick Plus

This a consecutive cross-sectional study of 95 phakic patients over the age of 40-years-old. By applying a short, vertical slit beam, the inferior angle at the scleral-limbal junction at 6 o’clock position was evaluated, photographed and assessed by a ratio...

Retinal vessel diameter in pseudoexfoliation

Pseudoexfolation (PEX) is characterised by deposition of fibrillary extracellular material on ocular and extraocular tissue. Studies have shown that deposition in vascular structures cause hypoxia and ischaemia. In the eye, a decrease in blood supply to the optic nerve can...

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...

Investigating the effect of signal strength on mean retinal nerve fibre layer

The aim of this study was to determine the effect of signal strength on mean retinal nerve fibre layer (RNFL) using spectralis optical coherence tomography (S-OCT). Thirty normal subjects were imaged with S-OCT using variably dense Bangerter foils to alter...

Customised corneal crosslinking with supplemental oxygen

In this prospective interventional case series, the authors investigate using supplemental oxygen delivery during epithelium-on corneal crosslinking (CXL) with specially designed oxygen delivery goggles. Twenty-seven eyes of 24 patients underwent epi-on CXL with Riboflavin and Ultraviolet-A irradiation. At six months...

How common is optic disc drusen in young patients with NAION?

A retrospective notes review at two tertiary care centres was completed between 2009 and 2019. The inclusion criteria for the study was a diagnosis of nonarteritic anterior ischaemic optic neuropathy (NAION) in at least one eye, aged between 18 and...

Association of pendular waveform and retinal disorders

The authors aimed to evaluate the relationship between retinal disorders and pendular low amplitude high frequency components (PLAHF) waveform by collecting nystagmus eye movement recordings, electroretinography (ERG) and gene tests. Retinal disorders were diagnosed by clinical phenotype and genotype characteristics....

Fixation target position for increased limbus measurement accuracy with AS-OCT

The authors intended to determine the optimal gaze fixation points for lateral rectus and medial rectus muscle insertions using anterior segment - optical coherence tomography (AS-OCT) compared with intraoperative measurements. They recorded 46 lateral and 36 medial rectus muscles from...

Occult central retinal artery occlusion

Central retinal artery occlusion (CRAO) is a sight-threatening condition resulting from occlusion of the central retinal artery and hypoperfusion of the inner retina. Early on, fundal examination may be normal. The authors present a retrospective case series of 11 patients...

Test combination which could detect prodromal Alzheimer disease

The authors prospectively recruited a convenience sample of individuals aged over 65 and either with a diagnosis of mild cognitive impairment (MCI) due to Alzheimer disease or normal cognition. Other types of dementia and severe neurological conditions were excluded. All...
