Research Focus:
Age-Related Macular Degeneration and Stargardt’s Disease

Age-related macular degeneration (AMD) is a major cause of severe vision loss and irreversible blindness in middle-aged or elder people throughout the world, and has become a serious public health problem. AMD greatly influences health and life quality of the patients and bring a heavy burden of ideology and economy to individuals and our country. Stargardt’s disease (STGD), also called as juvenile macular degeneration, is an autosomal recessive hereditary disease that primarily occurs in the layer of retinal pigment epithelium. Likewise, tens of thousands of people suffer from complete vision loss due to STGD. Our study is mainly focused on the effect and mechanism of visual cycle dysfunction and lipofuscin buildup in the onset and progression of AMD or STGD, and target prevention and treatment of drugs accordingly.
