Eye scans detect signs of Parkinson’s disease up to seven years before diagnosis

A team led by Siegfried Wagner and Pearse Keane of Moorfields Eye Hospital and UCL Institute of Ophthalmology (and spanning UCL institutions) has identified markers that indicate the presence of Parkinson’s disease in patients on average seven years before clinical presentation.

The effects of anti-VEGF therapy for NvAMD on retinal vasculature

This retrospective consecutive case series examined 54 eyes of 54 treatment-naïve neovascular age-related macular degeneration (N-AMD) patients. Thirty-three eyes received intravitreal aflibercept injections, and 21 eyes received intravitreal ranibizumab injections with unaffected fellow eyes (54 eyes) as controls. All image...

Microperimetry of subretinal drusenoid deposits

Subretinal drusenoid deposits (SDD), originally termed ‘reticular pseudo-drusen’, have recently been identified by histology and optical coherence tomography (OCT) as aggregations located in the subretinal rather than the sub retinal pigment epithelium (RPE) space. These deposits affect the amount of...

Investigating the effect of signal strength on mean retinal nerve fibre layer

The aim of this study was to determine the effect of signal strength on mean retinal nerve fibre layer (RNFL) using spectralis optical coherence tomography (S-OCT). Thirty normal subjects were imaged with S-OCT using variably dense Bangerter foils to alter...

Objective vs. subjective torsion measures

This study aimed to explore the relationship between subjective and objective torsion in normal individuals with no manifest strabismus. The study included 118 eyes of 59 normal people aged >15 years using Heidelberg OCT and the Torsionometer. There were 27...

Characteristics of cherry red spot on optical coherence tomography

In this study the authors report optical coherence tomography (OCT) characteristics of cherry red spot from three cases of Tay-Sachs and one case of Niemann Pick diseases to determine associated factors and potential visual implications. This was a retrospective case...

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...

Four key questions and answers for glaucoma practitioners

In this discussion paper the authors pose four questions for the clinician diagnosing and monitoring glaucoma, and supply evidence-based answers. Worldwide, the most common functional test used to diagnose and monitor glaucoma is static automated perimetry, most typically with a...

Correlation between aqueous flare and macular microvascular status in diabetes mellitus

The authors report a cross-sectional study which was conducted to investigate the correlation between aqueous flare and macular microvascular status, assessed by optic coherence tomography angiography (OCTA) in diabetes mellitus. Fifty-two diabetic patients with non-proliferative retinopathy, 44 diabetic patients without...
