Retinal Therapeutics Lab

Novel molecular approaches in the treatment of retinal disease

In recent years a wealth of new information has become available on the causes of such retinal diseases as age-related macular degeneration, diabetic retinopathy and retinitis pigmentosa. This has generated an ideal environment to study new, molecular approaches to treating common retinal diseases. Additionally by combining treatments, potential synergies can be studied – more effective outcomes might be achieved by concurrently targeting multiple points of the pathogenic pathway. In a team approach using rodent, zebrafish and xenopus model systems, we are investigating such synergistic combination therapies, to correcting retinal cell apoptosis, protein misfolding and inflammation.

Cell-based therapeutics for age-related macular degeneration and retinitis pigmentosa

Cells can be used in two ways to repair damaged retina: to replace lost cells (tissue regeneration) or as vehicles to deliver drugs to the retina (a difficult undertaking because of the retina’s relative inaccessibility (e.g. the blood brain barrier prevents many drugs penetrating the retina). We are developing cell-based drug delivery techniques to allow for longer-term drug delivery and so avoid the need for repeated injections into the eye.

Molecular defects underlying retinal disease

Many of the commonest causes of retinal disease (e.g. macular degeneration, retinitis pigmentosa) arise from genetic abnormality. We continue to work on identifying the genes underlying retinal disease, as a means of developing better methods of diagnosis and more importantly to identify new therapeutic targets through a better understanding of disease pathogenesis.

Clinical trial in retinal disease

Macular degeneration is the commonest cause of blindness in the western World. We are developing links with a number of pharmaceutical companies to trial new treatments for macular degeneration (e.g. photodynamic therapy, intra-vitreal anti-VEGF therapies).
