There are usually no symptoms that you’re developing glaucoma until vision loss occurs, which is why it’s so important to have regular eye checkup. Your eye doctor can detect and treat high IOP before it progresses to optic nerve damage and vision loss.

It is a condition that cause damage to the optic nerve, which transmits information from the eye to the brain. It usually (but not always) is associated with high intraocular pressure (IOP). Left untreated, glaucoma can cause blindness.
