EYE - Vitreo-Retinal
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...

EYE - Neuro-ophthalmology
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...

Central serous chorioretinopathy (CSC), Differential diagnosis, Retinal disease, Serous fluid accumulation, Serous maculopathy
This is a review article looking at the differential diagnosis of subretinal fluid in the macula that could be diagnosed as central serous chorioretinopathy (CSCR). The authors have categorised them into 12 groups: neovascular diseases, vitelliform lesions, inflammatory diseases, ocular...
Ocular damage from laser pointers
This retrospective study of case notes from a tertiary eye centre over a five-year period, recruited nine children (12 eyes: eight boys) aged 9-15 years. Three presented with deteriorating vision whilst others had retinal changes noted as incidental findings at...Comprehensive review of inherited retinal diseases

EYE - Vitreo-Retinal
The authors offer an up-to-date review of inherited retinal diseases (IRDs). In each section the authors discuss the molecular basis of disease, genotype and clinical manifestation. They also discuss the investigation findings and current evidence in the treatment of the...
Vigabatrin-induced retinal toxicity detected by 30Hz ERG
The purpose of this study was to assess the role of 30Hz flicker electroretinogram (ERG) as a marker for measuring changes in visual function over time in children receiving vigabatrin. This was an observational study of 11 children with mean...Simulated ocular surgery: pars plana vitrectomy and scleral buckling surgery
See also Simulated ocular surgery and Simulated ocular surgery - strabismus surgery In this second article on ocular surgery simulation, we will discuss how vitreoretinal surgery can be simulated using high tech virtual reality modalities such as the Eyesi, as...Optical Coherence Tomography: A Clinical and Technical Update
This book is a comprehensive review of the clinical and scientific aspects of optical coherence tomography (OCT). The 255 pages are divided into 11 chapters, each written by a different group of authors. Part I provides viewpoints on the clinical...Intravitreal bevacizumab vs. ranibizumab in the treatment of macular oedema due to BRVO
This is a randomised, prospective, non-inferiority trial of 75 patients with macular oedema due to a branch retinal vein occlusion (BRVO) who received intravitreal injections of ranibizumab or bevacizumab after 1:1 block randomisation. This study is to measure the difference...Vitreomacular traction and full thickness macular hole
Clinical scenario: A 64-year-old lady presented to the clinic with a few weeks history of sudden onset of metamorphopsia, central blur and reduced vision in her right eye. The ocular examination and ocular coherence tomography confirmed right eye focal vitreomacular...Patients blinded by stem cells! How safe are they really?
Simerdip Kaur takes a look at the latest ophthalmology-related news stories and asks which are based on facts and which are ‘fake news’. Headline: Patients blinded by stem cells! How safe are they really? Ever since the successful results following...A patient report of pseudoxanthoma elasticum, angioid streaks and choroidal neovascularisation

Angioid streaks (AS) on their own do not cause many problems, with the majority of patients remaining asymptomatic [1]. However, once choroidal neovascularisation (CNV) occurs, the visual prognosis of the patient rapidly declines [2]. Treatment is imperative to try and...
