Eye problems caused by heart disease
1- Transient amaurosis
It is a temporary loss of vision in one or both eyes, which may be complete or partial, lasting for a period ranging from seconds to 30 minutes or longer.
Transient amaurosis is usually caused by the following diseases:
– Reduction of Blood pressure.
– Hypertension.
– Obstruction of the internal carotid arteries.
– Occlusion of the vertebral and basilar arteries.
– brain attack.
– High blood cholesterol.

2- Stroke in the occipital lobe
If the stroke occurs in the part of the brain responsible for processing vision, which is the occipital lobe, the patient may suffer from vision problems, the severity of which varies depending on the extent of the damage.

3- Retinal artery occlusion
High cholesterol may impede the flow of oxygenated blood to the retina, if part of it is deposited in the artery responsible for nourishing it, causing sudden loss of vision.
4- Retinal vein occlusion
A common disease in people with high blood pressure, it results from the presence of a blood clot in the retinal vein, leading to blurry vision and sudden or gradual vision loss.

5- Optic neuropathy
High blood pressure may increase the risk of optic neuropathy if the flow of oxygenated blood to it is interrupted, leading to vision loss, as a result of damage to nerve fibers.
6- Retinopathy
Vision loss resulting from high blood pressure may indicate a disease other than optic nerve damage, which is retinopathy, especially if it is accompanied by bleeding in the eye or the patient suffers from diabetes at the same time.
7- Glaucoma
In a study published in the Journal of Ophthalmology in 2021, researchers found that heart disease, specifically high blood pressure, is a risk factor for glaucoma.

8- Cataracts
A previous study found a relationship between heart disease and an increased risk of cataracts, a disease that can only be treated by performing a surgical operation, in which the doctor removes the affected lens and implants another one.
9- Macular degeneration
A study conducted by the Singapore National Eye Center revealed that people with heart diseases, such as atherosclerosis resulting from high blood cholesterol, are more susceptible to developing age-related macular degeneration.
A study published by the American Heart Association in 2021 reached similar results, showing that the risk of macular degeneration increases in patients with heart failure.

10- Xanthelasma
When high cholesterol is deposited under the skin, it causes bumps around the eyes and near the nose, which tend to be yellow in color, but they do not affect vision.
11- Aging arch
A gray or blue ring around the edge of the cornea usually appears with age, but it also forms when bad cholesterol in the blood is high.
