Symptoms of Glaucoma
In the early stages of the disease, most cases of open-angle glaucoma present no noticeable signs or symptoms. Vision stays normal and there is no pain. But, even without symptoms, irreversible damage can be happening to your optic nerve. If glaucoma remains untreated for a long period of time, you may begin to notice some symptoms. Some cases of angle-closure glaucoma, especially during an acute attack, are associated with symptoms, which are discussed below.
The main symptom of glaucoma is loss of peripheral vision. This means that you can see things clearly in front of you, but objects to the side and out of the corner of your eye may be missed. As the disease progresses, it may seem as though you are looking through a tunnel. Over time, the remaining forward vision may decrease and the field of vision narrow until blindness results.
