Somatostatin protects retinal pericytes

Diabetic retinopathy (DR) is a complication of diabetes, caused by high blood sugar levels damaging the retinal microvasculature. Mechanisms, such as oxidative stress and deposition of advanced glycation end products, leads to glial cell activation and neuronal apoptosis. Pericytes, contractile...

Laser pointer maculopathy

The objective of this study was to describe the potential clinical presentations of retinal pathology resulting from exposure to laser pointers. The study included eight eyes of seven patients. Mean age was 18.7 years (12-36). Most were accidental self-inflicted while...

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...

Visual outcomes after surgery for primary RRD in era of microincision vitrectomy

This is a prospective, multicentre, nationwide study between 2016 and 2017, to investigate the preoperative ocular factors, surgical techniques (pars plana vitrectomy (PPV) or scleral buckling (SB), or combined procedures) for rhegmatogenous retinal detachment (RRD) and postoperative best corrected visual...

Relating metamorphopsia severity and OCT findings in advanced epiretinal membranes

The authors present the findings of a retrospective study to correlate metamorphopsia and ectopic inner foveal layers (EIFL) or ‘central bouquet’ abnormality (CBA) in patients with advanced stages of epiretinal membrane (ERM) following the new OCT‐based grading scheme as described...

Effects of ‘inverted U method’ Nd:YAG laser posterior capsulotomy on anterior segment and IOL tilt

The study aimed to investigate the effects of the ‘inverted U method’ Nd:YAG laser posterior capsulotomy on anterior segment parameters, decentration and tilt of intraocular lens (IOLs) and visual acuity in 76 patients with posterior capsular opacification (PCO) after previous...

Comparison of thrombolysis and conservative management in acute retinal ischaemia

The authors present a retrospective cohort study of individuals presenting with acute, painless, monocular vision loss and diagnosed with acute retinal ischaemia. Reasons for exclusion were iatrogenic aetiology, transient vision loss, missing initial visual acuity data, more than 16 hours...

Gonioscopy: A Video Assisted Skill Transfer Approach

Gonioscopy is a critical part of the eye examination, a challenging technique to learn and although drawings and photographs are helpful, videos that demonstrate the technique and findings are particularly valuable. Interpretation beyond merely identifying whether there is a closed...

An introduction to research governance

Research is the process of acquiring new generalisable knowledge and should be fully integrated into health care work. There is a growing drive to encourage and further develop evidence-based practice in ophthalmology so that staff and patients benefit from improved...
