The vast complexity of primary open angle glaucoma: Disease genes, risks, molecular mechanisms and pathobiology

Primary open angle glaucoma (POAG) is a complex progressive optic nerve neuropathy triggered by both environmental and genetic risk factors. Several ocular tissues, including the ciliary body, trabecular meshwork and optic nerve head, and perhaps even brain tissues, are involved in a chain of pathological events leading to POAG. Genetic risk evidence for POAG came from family linkage-studies implicating a small number of disease genes (MYOC,...
