Dr. Stewart Shofner Expresses the Importance of National High Blood Pressure Education Month to Help Prevent Irreversible Eye Damage
Almost every month we raise awareness on a national level to a
specific cause or disease and May is not excluded. Dr. Stewart Shofner
of Shofner Vision Center in Nashville helps educate his patients and
others about the risks of high blood pressure, which can affect every
part of the body including the eyes.
According to the American Heart Association, an estimated 78 million Americans (one in three adults) have high blood pressure (hypertension). "During a dilated retinal exam, ophthalmologists can determine if a patient has high blood pressure," says Dr. Stewart Shofner.
National High Blood
Pressure Education Month raises awareness about the impact high blood
pressure can have on one's health. Educating patients about high blood
pressure and the need for control is essential. "High blood pressure can
cause serious damage to the retina," says Dr. Shofner.
Like other vessels, the blood vessels that supply blood to your eyes can be damaged by high blood pressure causing any of the following issues:
- Retinopathy. High blood pressure can damage the vessels supplying blood to your retina, causing retinopathy. Retinopathy may lead to bleeding in the eye, blurred vision and vision loss. Having both diabetes and high blood pressure increases a patient's risk for retinopathy.
- Choroidopathy. Fluid builds up under the retina due to a leaky blood vessel in a layer of blood vessels, which may cause distorted vision.
- Optic Neuropathy. Blood flow that is blocked can damage the optic nerve and kill eye nerve, which may cause bleeding within the eye or vision loss.
blood pressure readings suddenly become very high, but when they do, it
can cause severe changes in the eye. Other problems with the retina are
also more likely, such as retinal artery occlusion and retinal vein
occlusion. Since the central retinal artery and vein are the sole source
of blood supply and drainage for the retina, such occlusion can lead to
severe damage to the retina and blindness. In some cases, it can also
In most cases, the retina will heal if the blood pressure is controlled. However, some people with a "Grade 4" retinopathy will have irreversible damage to the optic nerve or macula. Dr. Shofner recommends that it is important to seek medical treatment for those having high blood pressure and sudden vision changes or headaches.
Controlling High Blood Pressure
Prescription medications are available for controlling high blood pressure. Another way to reduce HBP is by following a heart-healthy lifestyle. Eating healthy, regular exercise, maintain a healthy weight, avoid smoking or tobacco products, and limit alcohol consumption is critical for preventing HBP and managing it.
