Summary
Corneal diseases are often treated using donor tissue transplants. Nevertheless, donor tissue is unsuitable for treating the peripheral or limbal margin of the cornea. We have therefore developed a way to transplant sheets of limbal tissue (epithelium) grown in the laboratory from a patient's own cells, but this tissue lacks a foundation of connective tissue that we believe is essential for sustained healing. Thus, our aim is to develop a novel limbal transplant which contains both layers.
Pterygia, one of the most common ocular complaints in Australia and worldwide, are thought to originate from overexposure to UV light. We propose that UV-irradiation stimulate certain cells in the eye to produce cytokines, growth factors and enzymes which degrade scaffold proteins such as collagens. These enzymes may play a key role in the progressive and invasive nature of pterygia. Dissecting the mechanism(s) by which UV light induces these proteins will lead to new and more reliable therapies ....Pterygia, one of the most common ocular complaints in Australia and worldwide, are thought to originate from overexposure to UV light.
