why does high blood pressure affect eyes?

High blood pressure can damage the tiny, delicate blood vessels that supply blood to your eyes, causing: Damage to your retina (retinopathy). Damage to the light-sensitive tissue at the back of your eye (retina) can lead to bleeding in the eye, blurred vision and complete loss of vision.

Subconjunctival hemorrhage can also result from certain medical conditions including trauma, high blood pressure, eye infections, and bleeding disorders. The straining associated with vomiting, coughing, or sneezing can also sometimes lead to subconjunctival hemorrhage.

High blood pressure results from the tightening of very small arteries called arterioles. Arterioles regulate the blood flow through your body. As these arterioles tighten (or constrict), your heart has to work harder to pump blood through the smaller space, and the pressure inside the vessels grows.

Blood pressure has an effect on glaucoma, but perhaps not in the way you might think. Glaucoma is characterized by optic nerve damage which results in vision loss, and elevated eye pressure (intraocular pressure) is the primary risk factor.

However, within this article, ocular hypertension primarily refers to increased intraocular pressure without any optic nerve damage or vision loss. Glaucoma is diagnosed when characteristic optic nerve and vision changes occur; typically with elevated eye pressure but occasionally with normal pressure.

High blood pressure can damage your health in many ways. It can seriously hurt important organs like your heart, brain, kidneys, and eyes. The good news is that, in most cases, you can manage your blood pressure to lower your risk for serious health problems.

Just as some eyes are more sensitive to high pressure, some eyes are more easily troubled by low pressures. A condition called hypotony is generally considered to be less than 6 mm Hg. When the eye pressure is too low it can cause several distortions of the retina, lens and cornea that can degrade vision.

Elevated IOP Vision loss from glaucoma occurs when the eye pressure is too high for the specific individual and damages the optic nerve. Any resultant damage cannot be reversed.

Ocular hypertension is a condition where the pressure in your eyes, or your IOP, is too high. Continually high pressure within the eye can eventually damage the optic nerve and lead to glaucoma or permanent vision loss. Some possible causes of ocular hypertension include: High blood pressure.

High blood pressure can damage the blood vessels that supply blood to your retina, the light-sensitive part of your eye. This is known as hypertensive retinopathy. It's important not to ignore chronic red eyes, since hypertensive retinopathy typically occurs after blood pressure has remained high for some time.

Ocular Hypertension Causes. Elevated intraocular pressure is a concern in people with ocular hypertension because it is one of the main risk factors for glaucoma. High pressure inside the eye is caused by an imbalance in the production and drainage of fluid in the eye (aqueous humor).

Why does it increase your risk of stroke? High blood pressure puts an extra strain on all the blood vessels in your body. This can make a stroke due to a clot (ischaemic stroke) more likely, because high blood pressure damages your blood vessels and makes them become stiffer and more narrow.

High blood pressure can damage the walls of the arteries and the heart itself. In some cases, high blood pressure could be a result of lifestyle, the environment, certain medications, or other conditions such as sleep apnea, kidney disease, or thyroid problems.

Hypertension and Hearing Loss When your blood pressure is high, your blood vessels are damaged. This damage isn't centered in one area of the body – your entire body is affected, including your ears. And when the blood vessels in your ears are damaged – and have a fatty plaque buildup – your hearing could be impaired.

High blood pressure (hypertension) can lead to many complications of diabetes, including diabetic eye disease and kidney disease, or make them worse. Most people with diabetes will eventually have high blood pressure, along with other heart and circulation problems.

Having high blood pressure ensures that there is good blood flow to the nerve tissues of the eye. However, according to new studies, long-term high blood pressure increases one's risk for developing glaucoma. Other studies have shown that having high blood pressure may be a risk factor for glaucoma.

Symptoms of high blood pressure are often unnoticed by the owner. A sudden or gradual onset of blindness can be the only outward sign that your pet may have high blood pressure. High blood pressure can worsen existing kidney disease, can cause bleeding in the brain, and will eventually affect every organ in the body.
