Abstract
Exfoliation glaucoma (XFG) is the most common identifiable secondary form of open-angle glaucoma in the world. It is an ocular manifestation of exfoliation syndrome (XFS), an age-related systemic disease characterized by deposition of extracellular fibrillar material in various tissues and organs. XFS/XFG has been studied in populations around the world, which has led to identification of genetic factors that play a significant role in disease pathogenesis. Here, we summarize current knowledge of the genetics of XFS/XFG and identify areas for future research.
