Roughly 2% of our population has this potentially blinding disease. If you have a history of raised eye pressure, a family history, or are over 55 years old, having a thorough eye examination to detect this disease is important.Most patients are effectively treated using eye-drops. A few with advanced damage or eye pressures unresponsive to medical treatment may need surgery. Laser treatment is also an effective alternative to eye-drops in some patients. Your assessment will involve tests of the pressure in your eyes, measurement of corneal thickness, photography and OCT scanning of your optic nerve, and a visual field tests (often done on a separate day).
