Professor Majlinda Lako, Newcastle University - £229,411

March 2021 – June 2024

Background and project history 

Previous research led by Professor Lako at Newcastle University developed a cell model of age-related macular degeneration (AMD) by turning patient skin cells into retinal pigment epithelium (RPE) cells, a key layer in the macula.
One of the main jobs of the RPE is producing, degrading and transporting proteins that are essential for our vision. If the RPE cells die or get damaged, as seen in AMD, it can cause light-sensing cells (photoreceptors) to die, which is what leads to sight loss.
This previous project by Professor Lako, also funded by the Macular Society, found some molecules that are more abundant in AMD cells compared to healthy cells. These molecules are produced by the RPE and move outside the cells in tiny bubble-like structures, known as exosomes, which help cells to communicate with each other. When AMD is present, the RPE exosomes can potentially be harmful for the photoreceptors.

Mitochondria are vital parts of every cell. They create the energy that cells need to survive and carry out tasks. The important layer of cells in the back of the eye called the retinal pigment epithelium (RPE) requires a large amount of energy, so the mitochondria can get stressed. Over time and with age these mitochondria get damaged, and we see higher amounts of damage in patients with AMD. This work aims to understand what happens to these mitochondria when they age and get damaged, how we could slow or stop this damage and whether that could slow or stop the progression of AMD.

Research summary

Many people with sight loss or macular disease require extra support from eye clinics, charities and low vision services. However, often those who need it most are not aware of the resources available. Professor Dickinson, from the University of Manchester, looked to create a chat-bot assistant to help answer these questions and signpost patients to useful resources.

Professor Graeme Black, University of Manchester - £164,042

April 2018 – September 2021

Creating eye cell models from patients with early onset macular degeneration to better understand causes and possible treatments for both early onset macular degeneration (EOMD) and age-related macular degeneration (AMD).

Dr James Whiteford, Queen Mary University of London - £148,991

May 2019 - April 2022

Research summary

Wet age-related macular degeneration (AMD) can lead to rapid sight loss. We currently have treatments which work well for most. However, for some people, the drugs don’t work. This project looks at a different way to treat wet AMD, which could help them.

Dr Jacqueline van der Spuy, University College London - £200,000

There are very few treatments available for macular dystrophies, which are caused by faulty genes. One macular dystrophy is Doyne honeycomb dystrophy, which causes central vision loss in adults. Research at University College London aims to use gene therapy to treat Doyne honeycomb dystrophy patients.

Dr Ruth Hogg, Queens University Belfast - £113,860

Many risk factors are known to be involved in the development of age-related macular degeneration (AMD). Although we still do not know which are the most important. Using health data from thousands of older people with and without AMD, Dr Ruth Hogg aims to better understand the role these factors play.

What’s the problem?

People with macular disease often lose some or most of their central vision due to the deterioration of their macula. To compensate for the loss in central vision, using the remaining peripheral (side) vision is often required. This is called eccentric viewing. 
A key problem is that the areas of the eye used in eccentric viewing are not well suited to fine-detailed tasks. Some people rely on technology like apps, tablets and smartphones to help, although many still have trouble reading and seeing detailed images. It’s thought that changing how these apps display images could improve reading speed, face recognition and fine detail vision (acuity).

Prof Andrew Dick, University of Bristol - £243,732

This project will investigate two molecules involved in energy production and immunity in the cells of the macula. We know from a previous Macular Society funded project at Bristol University that the loss of these molecules disrupts cell metabolism, and causes cell ageing and harmful inflammation - all of which are central to the progression of AMD. This research will look at how these molecules work in the cells and investigate whether, by introducing more of them, we could restore cell health.

Dr Jamie Ellingford, University of Manchester - £249,950

This research will help our understanding of what gene changes, or combination of gene changes, are involved in macular dystrophies. Understanding the genes and the variants that are responsible for macular dystrophies is important, so that more patients can receive a correct diagnosis and to develop treatments for these genetic conditions.
