It's unusual for a black eye to develop unexpectedly, when there hasn't been an injury, but a possible explanation is high blood pressure causing a capillary to burst, or one of the conditions listed below.

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).

6. Hypertension medications – Some high blood pressure medications, such as tetrahydrozoline, can cause small pupils.

Causes of black eye When the small blood vessels, or capillaries, beneath the skin break, blood leaks into the surrounding tissue. This is what causes the discoloration or bruising. Most black eyes aren't serious, but they can sometimes be an indicator of a medical emergency such as a skull fracture.

High blood pressure restricts the amount of oxygen getting to your eyes, which can raise your odds of AMD. From: What Causes Age-Related Macular Degeneration? SOURCES: U.S. National Library of Medicine: "Macular Degeneration."

Symptoms of Severe High Blood Pressure If your blood pressure is extremely high, there may be certainsymptoms to look out for, including: Severe headaches. Nosebleed.

Medications (including some used to lower blood pressure) can also cause a red face as a side effect. However, one thing that's very unlikely to be behind your red face is high blood pressure.

We now know that certain blood pressure pills have been linked to worsening glaucoma. Diuretics have a strong link with progression of glaucoma in the eye, and the calcium channel blockers have also been linked to progression of glaucoma.

What doctors do know is that increasing blood pressure does result in increasing eye pressure, possibly because high blood pressure increases the amount of fluid the eye produces and/or affects the drainage of that fluid out of the eye.

Specifically, ocular perfusion pressure, which is essentially the difference between blood pressure and eye pressure, is a risk factor for glaucoma diagnosis. This situation can occur in patients who naturally have low blood pressure, but also for patients with high blood pressure who are overtreated with medications.

Over time, high blood pressure can cause damage to the retina's blood vessels, limit the retina's function, and put pressure on the optic nerve, causing vision problems. This condition is called hypertensive retinopathy (HR).

In general, nosebleeds are not a symptom or result of high blood pressure. It is possible, but rare, that severe high blood pressure may worsen or prolong bleeding if you have a nosebleed. Causes shown here are commonly associated with this symptom.

Most commonly, this happens in older people with arteriosclerosis and possibly vascular disease, and is due to small clots breaking off of the walls of arteries and then lodging in the vessels of the eye. The clot obstructs the blood flow to the retina, and the vision blacks-out.

Many medications, including those that treat allergies, high blood pressure and depression, can also aggravate dry eye syndrome. Common symptoms of dry eye syndrome include: Burning sensation. Itchy eyes.

Fanelli says. Blood pressure tends to downregulate during sleep hours in the early morning, which is also the time of day where IOP tends to be the highest. These two opposing factors can have a duplicative effect in reducing OPP during nocturnal hours, which may allow increased damage to the ocular nerve head.

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.

A hypertensive crisis is a medical emergency that causes your blood pressure to rise above 180/120 rapidly. If your blood pressure gets too high, it can cause damage to your organs and other potentially life-threatening complications. Symptoms of a hypertensive crisis include: Blurry vision or other vision problems.
