Glaucoma affects 2% of Kiwis over the age of 40 years of age, and about 10% of those over 70. Many people with the disease don’t know they have it.
Vision loss associated with this disease is often called tunnel vision. This may mean a person can see straight ahead with their central vision, but not notice things off to the side, above or below.
It can often go undetected as people remain without symptoms for a number of years while visual loss slowly happens. The good news is regular eye tests, early detection, and subsequent treatment can prevent vision loss.
