A comparison of colour vision tests in the presence of contrast sensitivity loss

This study analyses the effect of contrast sensitivity (CS) loss on colour vision (CV) testing, using a variety of colour vision tests. The authors used a computer model for CS loss to determine its effect on CV testing scores for...

Strabismus detection by digital photography

The overall aim of this study was to develop an algorithm to acquire, validate and analyse digital photos to detect manifest strabismus and inform whether referral is required. The authors describe a method to measure the difference in location of...

EQUALeyes: Illuminating insights into using health data, AI and inclusion

Reflecting the Bloomsbury Festival theme of Human.Kind, and current public conversations on the benefits and potential threats of AI, we bring together leaders in the field of healthcare AI to discuss key issues, with a special focus on eyes.

Contemporary glaucoma therapy: spoilt for choice

The goal of glaucoma management is to prevent visual loss and disease progression in the patient’s lifetime through effective lowering of intraocular pressure (IOP), the primary modifiable risk factor in glaucoma. Sustained and consistent IOP reduction is key to halting...

Landmark review of glaucoma treatment and research published by Moorfields-led team

Four world-leading experts, including Hari Jayaram and Gus Gazzard from Moorfields, have combined their knowledge with the findings from over 150 peer-reviewed study publications to produce a landmark paper published in the Lancet.

Bovine pericardium scleral patch graft associated scleritis: Ahmed valve implant for pupillary block glaucoma

Processed bovine pericardium is a lyophilised collagen sheet used as a surgical armamentarium. It renders the material antigenically inert with minimal inflammation [1]. Sclera patch pericardium graft (Tutopatch) is a collagenous membrane derived from solvent preserved, irradiated bovine pericardium [2]...

Commonwealth nations join forces to prevent blindness from diabetes

More than 70 representatives from 10 Commonwealth countries (in the African, Caribbean and Pacific regions) and Indonesia gathered at a five-day workshop in November 2014 to establish district or national plans to reduce blindness from diabetic retinopathy (DR). The event...

The results of the last survey Apr21

There was a really fascinating response to the last edition’s practice variance survey. Strictly speaking, I cheated and this was not really about practice variation, but more about your impressions about what represents negligent practice. For the first time ever,...

Retinal changes in Leber hereditary optic neuropathy

The objective of this study was to describe the changes in the retinal ganglion cell complex (GCC) relative to the retinal nerve fibre layer (RNFL) over time, in patients with Leber’s hereditary optic neuropathy (LHON). For this study, 21 patients...

Static subjective visual vertical (SVV) in the normal visual system

Graviception is the perception of a persons’ orientation relative to gravitational force. This can be measured by means of subjective verticals, which can be divided into three tests: subjective visual vertical (SVV), subjective postural vertical (SPV) and subjective haptic vertical...

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)...

LASEK vs. epi-LASIK for myopia: meta-analysis

Previous studies have produced inconsistent conclusions on the relative benefits between LASEK vs. Epi-LASIK. LASEK uses 20% alcohol to separate an epithelial flap from the Bowman membrane. After ablation, the epithelial flap is repositioned onto the cornea. Epi-LASIK creates the...
