Symptoms of glaucoma vary depending on the specific type of glaucoma: chronic open-angle glaucoma or acute closed-angle glaucoma.
There are generally no symptoms in the earliest phases of the development of chronic open-angle glaucoma, the most common form of glaucoma. As pressure builds up inside the eye (Increased intraocular pressure), it gradually damages the optic nerve. If not diagnosed and treated promptly, this can lead the development of blind spots, especially in the peripheral areas (side) of vision. If left untreated, these spots gradually become bigger until blindness occurs.
Acute closed-angle glaucoma is the result of sudden and severe increased intraocular pressure due to a blockage of fluid drainage by the iris, the colored part of the eye. Symptoms of acute closed-angle glaucoma occur suddenly and can rapidly lead to blindness if not treated emergently. Symptoms include blurred vision, severe eye pain, eye redness, severe headache, seeing halos or rainbows around lights, nausea and vomiting.
Acute closed-angle glaucoma is less common than chronic open-angle glaucoma and is a medical emergency....more about Glaucoma »

Glaucoma has no symptoms at first but over the years can steal its victims' sight, with side vision being affected first. (Source: Genes and Disease by the National Center for Biotechnology)
At first, there are no symptoms. Vision stays normal, and there is no pain.
However, as the disease progresses, a person with glaucoma may notice his or her side vision gradually failing. That is, objects in front may still be seen clearly, but objects to the side may be missed. As the disease worsens, the field of vision narrows and blindness results.

At first, open-angle glaucoma has no symptoms. Vision stays normal, and there is no pain. As glaucoma remains untreated, people may notice that although they see things clearly in front of them, they miss objects to the side and out of the corner of their eye.
Without treatment, people with glaucoma may find that they suddenly have no side vision. It may seem as though they are looking through a tunnel. Over time, the remaining forward vision may decrease until there is no vision left. (Source: excerpt from Facts About Glaucoma: NEI)
