Glaucoma is the second-leading cause of blindness in the US for people over the age of 40; the most common form is primary open-angle glaucoma (POAG). It has been suggested that inflammatory markers have a role in the development and the progression of glaucoma (GL). High-sensitivity C reactive protein (HsCRP) is an inflammatory marker that has been linked to cardiovascular disease and a possible link to GL. Although a number of studies have found a link between CRP and GL; POAG, normal tension glaucoma (NTG), exfoliation glaucoma (XFG), Exfoliation syndrome (XFS), other research has shown the opposite.
