Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...

Ocular manifestation of Marfan Syndrome

This repeated cross-sectional study collected data in 2003-2004 and 2014-2015 to investigate changes in ocular features in Marfan syndrome (MFS) fulfilling the Ghent-2 criteria. Ghent-2 is a set of criteria by which MFS are identified and includes aortic root aneurysm...

Microperimetry measurements in anisometropic amblyopia

The authors aimed to evaluate retinal sensitivity and fixation characteristics in children with anisometropic amblyopia by macular analyser integrity assessment (MAIA) microperimetry and to compare the results between amblyopia and fellow eyes. The study included 39 children; 21 female –...

Changes in drusen and retinal layer volumes prior to CNV development

This retrospective longitudinal study looked at patients with wet age-related macular degeneration (AMD) in one eye who subsequently developed wet AMD in the fellow eye. The aim was to discover whether drusen characteristics or volumes of retinal layers correlate with...

Restoration of colour perception in patients with retinitis pigmentosa

This is a case series testing the feasibility of using bioelectronic retinal prostheses to partially restore colour perception in seven patients with advanced retinitis pigmentosa. Bioelectronic retinal prostheses are able to bypass degenerated photoreceptors to directly stimulate the inner retinal...

What is paracentral acute middle maculopathy?

This is a review article characterising a clinical entity called paracentral acute middle maculopathy (PAMM). The article highlights the fact that retinal capillary plexuses are organised predominantly into three trilaminar capillary layers occupying the area between the nerve fibre layer...

Retinal findings in COVID-19 patients

This is a single centre cross-sectional study from Brazil between 20 to 23 May 2020, with a total of 18 patients; nine male and median age was 62.5-years-old. 10/18 (55.6%) had retina abnormalities upon dilated eye examination. Flame-shaped haemorrhages were...

Genetics counsellors in inherited retinal disease clinics

This is a questionnaire-based study from the USA of genetics counsellors with a primary role working within ophthalmology services. The purpose was to investigate the roles currently undertaken, to assess workload, and to acquire data on the experience of genetics...

Is thrombolytic treatment warranted for central retinal artery occlusion?

Central retinal artery occlusion (CRAO) is a subtype of acute ischaemic stroke which results in severe visual loss. Acute CRAO is equivalent to a brain acute ischaemic stroke (AIS), as the obstruction of the central retinal artery (CRA) causes end-organ...

In conversation with Pearse Keane (2018)

AI was a hot topic at the 18th Congress of the European Society of Retina Specialists (EURETINA), following the publication of important findings in relation to using this technology in diagnosing retinal disease. We were delighted to catch Pearse Keane,...

Understanding the pachychoroid disease spectrum

This article provides a comprehensive review of the pachychoroid disease spectrum, a group of chorioretinal disorders characterised by abnormal choroidal thickening and various pathological changes in the choroid, retinal pigment epithelium, and retina. It also highlights the controversies and knowledge...
