Early detection of open angle Glaucoma is extremely important, because there are no early symptoms. Fortunately, routine eye exams are a major factor in early detection. People with a family history of Glaucoma should be checked at intervals in their 30s to establish a baseline. Initially, detection is based often on intraocular pressure readings, but also includes observation of the optic nerve as well as evaluation of optic nerve function using visual field tests.
