If the entire nerve is destroyed, blindness results. Glaucoma is a leading cause of blindness in the world, especially in older people. Early detection and treatment by your ophthalmologist are the keys to preventing optic nerve damage and vision loss from glaucoma.
Glaucoma is usually a slow disease. Untreated glaucoma takes on an average of 15 years to progress from early damage to blindness with an IOP of 21 to 25 mmHg, 7 years with 25 to 30 mmHg, and 3 years with a pressure more than 30 mmHg.
