Atrophy and anti-VEGF

The aim of this study was to investigate treatment factors, along with ocular and systemic factors for their association with macular atrophy (MA) incidence in eyes with neovascular age-related macular degeneration (nAMD) treated with anti-VEGF aflibercept or ranibizumab according to...

Uveitis‐Glaucoma‐Hyphaemia syndrome retrospective case-control study

The authors present the findings of a case-control study aiming to assess uveitis‐glaucoma‐hyphaemia (UGH) syndrome, focusing on the resolution, glaucoma development and risk factors. The authors compared three groups each containing 71 patients. Each group contained patients with UGH syndrome,...

Aug/Sep 2015 Quiz 1

History A 60-year-old woman was referred to ophthalmology with a suspected left eye choroidal naevus. Visual acuity was unaffected in both eyes and she was asymptomatic. Ocular history and medical history were unremarkable. Questions Figure 1: Fundus photograph. 1. What...

Acute macular neuroretinopathy

Acute macular neuroretinopathy (AMN) is a rare condition that typically affects young women and presents with photopsia and paracentral scotomata [1]. We describe a case of severe acute macular neuroretinopathy, following Covid-19 infection. A 30-year-old woman presented to the urgent...

Deciphering dark retinal patches

We present a case of bilateral extensive dark without pressure (DWP) located outside the retinal vascular arcades in a young female. This retinal finding is benign but, in some instances, darkened retinal patches could be associated with potential sight-threatening conditions....

Inflammatory macular holes

The authors present a case of closure of a full thickness macular hole in a patient with Behçet’s disease, without surgery. The 23-year-old male they describe presented with a history of recurrent oral aphthous ulcers and a genital ulcer. Ocular...

Automated Bruckner device accuracy

The authors developed a Bruckner device, examined volunteers and determined the relation between the luminance of the red fundus reflex and eye rotation. Eye rotation was varied continuously both horizontally (-7 to 8 degrees) and vertically (five degree total range)...

Fluorescein angiography and OCT in myopic CNV

Fluorescein angiography (FA) and spectral-domain optical coherence tomography (OCT) are the most common examinations used in the management of anti-VEGF therapy in choroidal neovascularisation (CNV). In comparison to FA, OCT provides a noninvasive evaluation of the macula. Myopic CNV are...

RPE use similar pathway to regulatory T cells to inhibit immune response

Retinal pigment epithelial (RPE) cells form an important part of the blood-retinal barrier that protects the neuronal cells responsible for sight. RPE cells are involved in innate and adaptive immune responses via expression of surface molecules and release of cytokines....

Role of fundus autofluorescence patterns and baseline atrophy area on geographic atrophy progression

Central geographic atrophy (GA) is one of the morphological sub types of late-stage macular degeneration. The natural course of the disease is characterised by expanding areas of macular atrophy, which cause absolute scotoma. Fundus autofluorescence (FAF) is derived from lipofuscin...

Reduced blood flow and age-related macular degeneration

This was a prospective cross-sectional study assessing changes in blood flow velocity in patients with age-related macular degeneration (AMD) using a retinal function imager. Sixty eyes with wet AMD were compared to 53 control eyes and the average blood flow...

HtrA1 enhances cell senescence

A genetic basis for age-related macular degeneration (AMD) has been greatly advanced in recent years. The role of identified pathways such as complement factor H in AMD has been widely investigated. However, the effect of other gene variants identified by...
