High blood pressure can lead to impaired vision

Blurred vision may not always be attributed to a refractive error. High blood pressure, also known as hypertension, can cause problems with the eyes too. However, many sufferers do not discover the relationship, because they do not know that they have high blood pressure. The diagnosis is important in order to prevent more serious health consequences in time.

Many patients with hypertension know nothing of their suffering. The disease often goes a long time without any symptoms. This does not mean that it is harmless because of that. On the contrary, too high blood pressure can have far-reaching health problems. These can include vision problems.

High blood pressure is very dangerous because it damages the blood vessels. This creates a conditional called atherosclerosis, which means that the arteries stiffen and constrict. The consequence of this is an impaired blood flow to the body and its organs, which can affect the heart, kidneys, brain, and even the eyes.

When hypertension isn’t treated the eyes can be permanently affected. High blood pressure acts on the retinal vessels, and thus the optic nerve. Similarly, the risk rises to develop a blood clot in the ophthalmic vein.

Also glaucoma is often associated with a high blood pressure. Glaucoma is when the internal pressure of the eye increases, causing optic nerves and retinas to be damaged. Even a stroke due to high blood pressure can be expressed by vision problems.

If the retina of the eye is affected by chronic or acute hypertension it can lead to permanent problems. The vessels of the fundus are affected by sustained high blood pressure. Firstly, the small supply of veins to the retina are affected (also known as retinal veins) meaning that the blood lacks the necessary oxygen required by the eyes. The choroid vessels can be damaged. The choroid is feeding the sensory cells of the retina, which are also called photoreceptors. With them, the eye receives light pulses, converts it into a nerve impulse and relays the information to the brain.

High blood pressure deforms the retinal vessels. They are close and form outgrowths or close entirely. With vascular damage, the supply of nutrients with the eye cannot be ensured. It leaves deposits and can cause bleeding in the retina. Thus, the nerve fibres of the retina can eventually die.

If the hypertension is very strong and the retinal damage is already well advanced, further complications may occur. The optic nerves within join together with the nerve fibres and swell.

All of these changes can cause mild to severe vision problems. It is therefore always advisable to think that if the cause is high blood pressure, there is something that you can do to help. If hypertension is recognized early and treated properly it can reduce retinal damage and visual loss can be avoided. In many cases, the condition of the retina can go back to normal and the vision problems can disappear.

The traditional Chinese medicine, blurred vision can be caused by liver heat. This heat can be treated with water cress, onions, green mustard, turmeric, basil, bay leaf, cardamom, marjoram, caraway, fennel, dill, ginger, black pepper, horseradish, various mints and even angelica. Black sesame seeds are also in the alternative medicine literature as recommended for visual disturbances. Always discuss eye problems with your doctor or ophthalmologist.
