Research Focus:

age-related macular degeneration and autosomal recessive Stargardt disease

Age-related macular degeneration (AMD) is a major cause of severe vision loss and irreversible blindness in the world’s adults and the China’s middle-aged or elder people, and has become a serious public health problem. AMD greatly influences on health and life quality of middle-aged or elder people in China and brings a heavy burden of ideology and economy to individuals and our country as well as restricts economic development of our nation. Autosomal recessive Stargardt disease (STGD1) is a macular dystrophy caused by mutations in the Abca4 gene, and initially occurs in the layer of retinal pigment epithelium. Tens of thousands of people suffer from complete vision loss due to STGD1. Our study is mainly focused on the pathogenesis and drug discovery of AMD and STGD1.
