Aston Academy Investigates Sight Threatening Disease

27.01.2006


Aston Academy of Life Sciences, the clinical research hospital of Aston University, has recently been commissioned to assess the efficacy and safety of a specialist drug, Posurdex (Allergan Ltd, UK), which is used in the treatment of patients who suffer from a sight threatening condition, called macular oedema.



It is estimated that the condition, which is caused by occlusion (blockage) of the central or branch retinal veins in the eye, affects over two and a half million people worldwide, with over 245,000 people in the UK being affected, most of whom are untreatable. This phase III clinical trial commissioned at the Academy and other sites in the UK, Europe and Worldwide offers the hope of significant improvement in vision for those who suffer with the condition.

The disease affects the macula, a tiny oval area at the centre of the retina which is responsible for "central vision" and is important for tasks that require detailed vision, such as reading and driving. The disease process involves the build up of fluid causing swelling of the macula which can result in severe visual disabilities and blindness particularly among people with diabetes.


The condition is also specifically associated with other visual conditions including diabetic retinopathy, retinal vein occlusion and uveitis (the inflammation of the part of the eye containing the iris, cillary body and choroids).

Once implanted, Posurdex releases dexamethasone to the targeted disease site at the back of the eye. Dexamethasone, a corticosteroid, reduces the macula swelling.

In relation to this new trial the Academy hosted a mini convention on 25 January, which was attended by 18 of the UK’s leading consultant retinal specialists and a number of research scientists from Aston and other Universities. They discussed the use of Anti-VEGF (Vascular endothelial growth factor) for the treatment of age-related-macular degeneration (AMD) through injections into the back of the eye.

Managing Director of the Academy and a Reader in the School of Life & Health Sciences at Aston University, Dr Sarah Hosking said: "These new interventions for AMD mark the start of an exciting new era for the potential treatment of the many patients with this debilitating and often blinding condition. The Academy will act as a hub of clinical research activity at the University, involving some of the UK’s leading retinal specialists. This Phase III clinical trial is the first step, however studies are likely to extend into the development of other related treatments drawing on expertise from our School of Pharmacy and expert ophthalmologists. Patients will be referred to the Academy from all over the Midlands by partnering ophthalmologists".

Aston Academy of Life Sciences also offers a range of ophthalmology services including cataract and refractive surgery, as well as MRI scanning to patients. Patients can be referred by doctors or optometrists or can simply refer themselves.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
