Summary
Cataract is the major cause of blindness worldwide. At present the only treatment for cataract, is surgery. This, however, is associated with complications (e.g. posterior capsule opacification), is expensive (a major component of the Health budget) and cannot keep pace with the incidence of cataract in developing nations. In addition, due to the greying of the community , this problem will be of increasing importance in the future. For prevention, we need to understand why cataract develops.

Summary
Age-Related Macular Degeneration (AMD) is the leading cause of irreversible blindness in the aged population in the developed world, and it is one of the least understood retinal diseases. AMD is a slow, progressive and painless condition that affects the macula, the small central part of the retina that allows one to see fine detail clearly. With the ever-increasing human life expectancy, the prevalence of AMD (15-30%) in the age group of over 75 years will significantly increase, causing enorm ....Age-Related Macular Degeneration (AMD) is the leading cause of irreversible blindness in the aged population in the developed world, and it is one of the least understood retinal diseases. AMD is a slow, progressive and painless condition that affects the macula, the small central part of the retina that allows one to see fine detail clearly. With the ever-increasing human life expectancy, the prevalence of AMD (15-30%) in the age group of over 75 years will significantly increase, causing enormous social and financial problems for the community. In spite of the significance of this problem, the exact cause of AMD is not yet known, and there is no permanent effective treatment or cure for the condition. One of the major obstacles hindering any advances towards the development of intervention strategies or therapies is the lack of an appropriate animal model. Currently, the animal models that are available for ocular diseases do not fit the human AMD situation. This project aims to characterize the first animal model for retinal degeneration caused by abnormal functioning of the retinal pigment epithelial cells (RPE). The main role of RPE cells is the phagocytosis and digestion of the continuously growing and shed light receptor segments in the eye. Their normal functioning therefore is vital to maintaining good vision. The availability of such an animal model will allow us to learn more about the changes that might occur in the eye leading to the development of AMD and to design strategies to prevent or delay progression of the condition.Read moreRead less
Dissecting The Pseudoexfoliation Syndrome With Complementary Genetic, Proteomic And Biophysical Strategies

Summary
Pseudoexfoliation syndrome (PEX) is an eye condition in which flaky material deposits in the eye, greatly increasing the risk of cataract and glaucoma which can lead to blindness. PEX is also associated with heart disease, strokes and aneurysms. Cataract surgery in PEX patients has a higher rate of complications. In this project we will determine the nature of PEX material and why it forms. This knowlege will facilitate better diagnosis and treatment of PEX preventing associated blindness.
