Glaucoma is the second-leading cause of blindness in America. That is why it is important for people to do all that they can to prevent glaucoma. There are several factors that can cause a person to develop glaucoma, but every type of glaucoma is caused by optic nerve damage. If the optic nerve is damaged, then vision loss can result. If you have noticed changes in your vision, then you should contact one of the eye doctors in Raleigh. Comprehensive eye exams help detect glaucoma, and it can be treated before it gets worse.
What Causes Glaucoma?
The exact causes of glaucoma are not known, but health care providers do understand the general characteristics of it. The most common form of this condition is primary open-angle glaucoma. This occurs when the eyes are unable to properly drain fluids. As a result of this, the pressure inside of the eye increases, and the optic nerve gets damaged. Optic nerve damage can also result if there is not enough blood reaching the optic nerve.
Angle-closure glaucoma is a less common form of this condition. This occurs when there is a blockage in the angle between the cornea and iris. It can permanently damage in vision. Abnormal eye conditions, physical injuries, medications and eye conditions can cause glaucoma.
In order to prevent glaucoma, one has to understand the risk factors. Below are some of the risk factors:
- Older Age: The natural aging process puts a person at risk for developing glaucoma. Most people who have glaucoma are over the age of 60.
- Asians And African Americans: These two groups are at an increased risk for developing glaucoma.
- Cardiovascular Disease and Diabetes: Both of these conditions increase glaucoma risk, so it is important for them to get treated properly.
- Family History: People who have a family history of this condition are more likely to develop it.
- Corticosteroid Use: Corticosteroids are often prescribed to patients who have lupus, arthritis and other autoimmune conditions. They can increase the risk of glaucoma.
Diagnosis And Treatment
Comprehensive eye exams include checking for glaucoma. Our eye doctors in Raleigh evaluate the patient’s retina, measure the thickness of the cornea and check eye pressure. Vision loss can be prevented if glaucoma is detected early. Medications and surgery are the standard treatments for glaucoma.
