Mapping areas to target location of vision screening services

In this study, the authors analysed data from a community vision screening program to determine the efficiency of vision screening in reaching lower income populations. The study used ArcGIS (Esri) mapping software to develop a visual representation of areas needing...

Developing a unified approach to low-vision care

RNIB’s Preeti Singla and Louise Gow introduce the Adult Low Vision Service Quality Framework. For individuals living with visual impairment, access to high-quality low vision services can be life changing. Yet, across the UK, these services remain fragmented, with significant...

Vision loss during Eylea treatment for AMD

This report investigated patients who lost more than two lines of vision despite periodic injections of aflibercept and explored the factors associated with vision loss. One hundred and ninety-six eyes were included in this study over a two year period....

Mechanism of colour vision involvement in multiple sclerosis

There is evidence to show that the optic nerve and retina are affected in multiple sclerosis (MS) even without any clinical evidence or history of optic neuritis (ON). MS without optic neuritis causes colour-vision deficit, however, the evidence for selective...

Children with Vision Impairment: Assessment, Development, and Management

Childhood blindness is a major public health concern worldwide with several implications ranging from a child’s development, education, and employment opportunities to social and functional challenges. This book offers a succinct, sequential approach to understanding conditions which lead to visual...

The invisible touch: a VISION 2020 LINK with Indonesia

Indonesia’s population, the world’s fourth largest, is spread across 6,000 inhabited islands. Whilst some areas (e.g. Kalimantan, Papua) are relatively sparsely populated, Java is the world’s most densely populated island, with twice the population of the UK in half the...

IN FOCUS - The achievements and lasting effects of VISION 2020

Blindness is a major public health problem globally. The first estimate of global blindness by the World Health Organization (WHO) in 1972 provided a figure of 10 to 15 million, which was considered an underestimate [1]. In 1999, an extraordinary...

Unexplained vision loss following exposure to combat

Non-organic vision loss (NOVL) is defined as a decrease in visual acuity or visual field without an identifiable organic cause. NOVL can be particularly challenging and time-consuming to diagnose, especially where the vision loss is superimposed on an element of...

VISION 2020 LINKS Programme: the Madagascar-Leeds LINK

Madagascar is a fascinating and culturally rich island which has an ‘exotic’ status in most people’s eyes. Yet it is among the poorest countries in the world. According to the World Bank, 92% of the population live on less than...

Bionic eyes: deciphering the neural circuitry of vision restoration

As the boundaries between technology and biology blur, retinal prosthetics, often dubbed ‘bionic eyes’, present a ground-breaking paradigm shift in addressing blindness. This article delves into the captivating scientific intricacies of these neural interfaces, exploring their mechanisms of action, current...

Time is vision in central retinal artery occlusion

Central retinal artery occlusion (CRAO) is a rare but devastating vascular episode that can have severe impact on vision. Treatment is very time-limited and needs to be initiated very quickly to salvage any vision. The majority of patients present to...

Cost-effectiveness framework discussion for vision screening

The authors present a discussion paper on hypothetical, but representative, examples of post-referral costs that may result from different screening options up to the point of discharge from specific services. Data was taken from a recent (2019) systematic review (with...
