8 Symptoms of Glaucoma

When most people hear about glaucoma, they typically associate it with being a condition that affects the eyes. Yet, being that this perception merely holds basic truth, many people remain ill-informed of the exact causes, types, and symptoms of the disease. Therefore, to gain a better understanding of the disease, one must first understand the specifics of its diagnosis. Glaucoma is a form of degenerative eye disease that consists of a combination of different types of related eye disorders that occur from the build-up of pressure inside the eye—causing damage to the optic nerve. The optic nerve is the optical component within the eye that is responsible for transmitting visual information from the eye to the brain. Nonetheless, when the optic nerve becomes damaged, it creates visual impairment and in some cases even blindness if the damage is too severe or goes without treatment.

Unfortunately, it is a known fact that glaucoma affects the lives of millions of people every year—the greatest impacted being those individuals of age 40 and older. Furthermore, according to scientific studies, it is also understood to be an inherited disease with signs and symptoms that are usually never exhibited until much later in life. There are several existing types of diagnosis for the form of eye disease and they are congenital, secondary, pigmentary, normal-tension, narrow-angle, and open-angle glaucoma—the most common type. However, even though there are various types of the disease, they all exude related symptoms which include blurred vision, distorted vision, vision loss, eye pain, nausea, sudden visual disturbance, headache, and rainbow halos.

1. Blurred Vision

Experiencing blurred vision is one of the many side effects of being diagnosed with glaucoma. This symptom is generally the result of having one of the two most common types of the disease—narrow-angle or open-angle. In the case of open-angle (angle remains open at the meeting of the iris and cornea), experiencing blurry vision occurs when the canals of the eye become clogged and due to its inability to drain properly, pressure builds within the eye and causes damage to the optic nerve. Whereas in the case of narrow-angle (angle narrowed or closed at meeting of iris and cornea), the eye canal is actually considered to be too narrow to allow for proper eye drainage.

This condition causes internal eye pressure to build which affects the optic nerve and ultimately impairs vision. In contrast to that of open-angle in which the eye appears to be normal, experiencing this type of vision is most likely to occur more rapidly with narrow-angle due to the actually closing of the eye canal that greatly contributes to the quick build-up of pressure. People who suffer from blurred vision typically have to consistently squint or strain their eyes to view objects that are either up close or at a distance.
