Signs and symptoms
One of the most troubling things about glaucoma is that you literally don't see it coming.
Primary open-angle glaucoma, the most common form, is usually painless and has virtually no symptoms. As a result, you may be unaware of your condition – or skeptical that you're at risk – until damage has already occurred. Even when damage to your sight
has occurred, you still may not notice because you may be unconsciously turning your head to compensate.
Importance of early detection
Because you don't feel anything with glaucoma, it's important to get checked regularly by your eye doctor. Your doctor has routine tests to detect high eye pressure, one of the main causes of glaucoma. The sooner high eye pressure is detected, the better chance you’ll have to preserve your sight.

A person in the early stages of glaucoma may not notice any visual changes because he may unconsciously turn his head to the side to compensate.
