Yes, there are many side effects of glaucoma, which depends on the various kinds of causes of glaucoma. Generally speaking, glaucoma is caused by the damage to the optic nerve of human beings' eyes and then gets worse over time, which is often associated with a buildup of pressure inside the eyes. Actually, glaucoma tends to be inherited and is the most frequently seen among the group of aged people. There are two main types of glaucoma, one is the open-angle glaucoma which is also called wide-angle glaucoma, the most common type of glaucoma. This kind of glaucoma possesses the characteristic that the structures of the eyes may appear normal while the fluid in the eye does not flow properly through the drain of the eye. And the other main type of glaucoma is the angle-closure glaucoma which is also called the acute or chronic angle-closure or narrow-angle glaucoma, a less common but able to cause a sudden buildup of pressure in the eye. People with this kind of glaucoma may suffer from a poor drainage because the angle between the iris and the cornea, where a drainage channel for the eye is located, will be too narrow. Besides, there are many other symptoms of glaucoma, such as seeing halos around lights, vision loss, and redness in the eye, eye that looks hazy which is particularly seen in infants, nausea or vomiting, pain in the eye, narrowing of vision or tunnel vision, and yes, blindness, when the condition is very serious. If people begin to have one of the above eye problems, they should go to the doctor's to seek immediate medical care as soon as possible in case that the condition gets worse.
