Glaucoma is typically an age related disease caused by long term increasing fluid pressure inside the globe of the eye. This prolonged and elevated pressure eventually damages the optic nerve in the back of the eye, and if left untreated will result in blindness. This condition has no symptoms, the elevated pressure does not cause eye pain or blurred vision, and the condition does not affect your central vision for many years.
How Glaucoma Can Affect Your Vision
HOW DOES THIS TESTING WORK?
A battery of tests is required to gather all the pertinent information, upon which to make a diagnosis of glaucoma.
The test required will determine both the structure of the optic nerve, as well as the function.
So “true” glaucoma testing actually involves examining the retina and optic nerve at the back of the eye for signs of the disease.
Glaucoma can cause slight to severe vision loss, and is often discovered only after the disease is present—that’s why glaucoma testing is so important.
