Glaucoma is a degenerative optic nerve disease that gradually rob’s one of their peripheral vision. Advanced technological testing such as an OCT scan can measure optic nerve thickness over time, while a computerized visual field testing can detect missing spots in one’s vision. Commonly known as the ‘silent thief of sight,’ regular ocular health examinations by your optometrist can help identify subtle risk factors for early diagnosis and treatment to preserve the gift of sight.
