What is glaucoma?
Glaucoma is a disease which can damage the optic nerve in an eye. Glaucoma results in vision loss or even blindness. As the disease progresses a stronger prescription would be necessary for th eyeglasses to work effectively. The disease occurs when the eye’s normal pressure from the fluid inside slowly rises. However, if caught early and an aggressive treatment program is used, the progression can be controlled and severe vision loss can be avoided/
What is the optic nerve?
Optic Nerve – More than one million nerve fibers in a bundle connecting the retina, light sensitive tissue located at the back of the eye, to the brain. Good vision needs a healthy optic nerve to occur.
Types of Glaucoma
Open Angle – This is the most common form of glaucoma and also known as chronic glaucoma. Open angle affects 70 to 80 percent of the people afflicted with this disease.
Normal Tension – Side vision becomes narrow and optic nerve damage occurs in people having normal eye pressure. Medicine can lower 30 percent of an eye’s pressure which for some people can slow the disease down. There is no guarantee and the disease may become worse despite reaching lower pressures.
Identifying potential risk factors is key to treatment and controlling the disease. A collection of medical history is very important to an aggressive treatment plan. Conditions like low blood pressure can be a contributing factor to normal tension glaucoma. If there are no risk factors found and identified, the treatment for normal tension glaucoma will be the same as the treatment for open angle glaucoma.
Closed Angle – Fluid at the very front part of the eye is blocked and cannot reach the eye’s angle and exit the eye out; part of the iris blocks its exit. There is a sudden increase in pressure associated for people who have this type of glaucoma.
If these symptoms occur it should be considered a medical emergency and the person should seek immediate treatment. If necessary the person should go to the nearest clinic or hospital. Without immediate treatment to improve the eye’s fluid flow, the eye can go blind in as little as two days or less. Quick medical attention, such as medicines and laser surgery can clear the blockage and prevent loss of sight.
Congenital – When a child is born with a defect in the angle of their eye it slows the normal flow of fluid drainage. This is normally associated with obvious symptoms; light sensitivity, cloudy eyes, and excessive watery eyes or tearing. Typically, conventional surgery is the safe and effective course of treatment; in infants medicines can have unknown adverse effects and be hard to administer. Good vision is possible if surgery is performed quickly.
Secondary – Complications from other medical issues can induce the development of the disease. Advanced cataracts, eye surgery, uveitis, specific eye tumors, or eye injuries are sometimes associated with secondary glaucomas.
