Glaucoma is a disease that affects the optic nerve, leading to loss of vision due to a build-up of pressure inside the eye (intraocular pressure). Glaucoma has been nicknamed the “sneak thief of sight” because the loss of vision normally occurs gradually over a long period of time and is often only recognized when the disease is quite advanced. Once lost, this damaged visual field can never be recovered.
- Glaucoma affects 1 in 200 people aged 50 and younger and 1 in 10 over the age of 80.
- Worldwide it is the second leading cause of blindness.
