Glaucoma is an eye disease that usually has no signs or symptoms, yet can lead to permanent vision loss if left undetected and untreated. Glaucoma is characterized by damage to the large nerve that connects our eyes to our brain, called the optic nerve. The optic nerve transmits the images created in our eyeballs to our brain, and a healthy optic nerve is needed for normal vision.
During your eye exam at DiGaetano Cataract Services, we will look for signs of glaucoma by examining the optic nerve head inside the eye. In addition, glaucoma is also often associated with an elevated eye pressure, so the eye pressure is also always measured during your eye exam. Vision loss from glaucoma starts with the peripheral vision, but can eventually progress to include all vision. If any evidence of possible glaucoma is detected on your eye exam, testing of your visual field can be performed. We use specialized equipment that is designed to detect evidence of glaucoma early so it can be treated before any vision loss occurs.
