ARN in North Africa

Acute retinal necrosis (ARN) is a rare cause of uveitis. This paper aims to outline the clinical features of 12 patients with ARN in a referral centre in Tunisia, North Africa. A retrospective review of case notes was carried out....

Acute retinal necrosis presumably caused by Epstein-Barr virus infection

Acute retinal necrosis (ARN) is an uncommon, but serious and potentially blinding condition. ARN is characterised by panuveitis, occlusive vasculopathy and progressive peripheral necrotising retinitis. The diagnosis is clinical but confirmation is sought via aqueous and vitreous sampling. Varicella zoster...

An unusual case of acute retinal necrosis

Case report A 40-year-old Caucasian male presented with a four-day history of redness and progressive painless reduction of vision in the left eye. His visual acuities were 6/4 in the right and 6/36 in the left. The left eye showed...

PRN Ranibizumab verses continuous aflibercept in UK clinical practice

This was a multicentre (21 UK hospitals), national EMR study on treatment naïve nAMD eyes, undergoing predominantly as needed (PRN) Ranibizumab or continuous (fixed or treat and extend - (F/TE)) Aflibercept (Af). The primary outcome was change in vision at...

Treat-and-extend regimen in treatment of patients with type 3 neovascularisation

Type 3 neovascularisation, also known as retinal angiomatous proliferation is a distinct subtype of neovascular AMD characterised by intraretinal neovascularisation. This retrospective study included 17 eyes diagnosed with type 3 neovascularisation who were changed from pro-re-nata (PRN) based treatment regime...

Possible COVID-19 related maculopathy

COVID-19 is being investigated as a potential cause for various ocular diseases, with growing evidence of related retinal vascular changes, that vary from isolated cotton wool spots and retinal haemorrhages to retinal vascular occlusions [1.2]. COVID-related macular affection has also...

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...

Adjuvant radiotherapy in orbital malignancy

This is a retrospective review of high dose volumetric modulated arc radiotherapy (VMAT) for adjuvant treatment of patients with orbital malignancy who had already undergone local excision or exenteration. VMAT differs from conventional external beam radiotherapy in that it is...

Evaluation of keratometry with a novel colour LED corneal topographer

The Cassini topographer (i-Optics), which analyses corneal shape based on the reconstruction of specular reflections on 679 coloured LEDs, generates keratometry and is the new machine being compared in this study with other keratometry devices. The prospective comparative study included...

Cataract surgery in uveitis patients

Cataract formation is a common complication of uveitis, causing up to 40% of vision loss in these patients. Cataract results from inflammation +/- corticosteroid therapy and is usually posterior subcapsular, but a small proportion have a rapid increase in nuclear...

How to survive the fluorescein round

One of the highlights of the medical retina fellowship programme at Moorfields is the Tuesday morning 8am fluorescein round. It is both exhilarating and terrifying. Exhilarating because they are slick presentations of the most interesting cases that each of the...

Refraction under GA in children using cycloplegic refraction as a reference

The authors aimed to compare the measurements of cycloplegic refraction and refraction (R1-1) under general anaesthesia (GA) with automated refraction (ARF) in paediatric patients and to determine the impact of GA on accommodation. The study included 222 eyes of 222...
