The network of blood vessels at the bottom of the eye, known as (Retina Vasculatur) or retinal blood vessels, is closely linked to heart health, which means that the problems we see in the eye can be directly related to health problems related to the heart and blood vessels of the human body.

Most ophthalmological medical examinations include examining the eye from the inside and the outside. To carry out this task, your ophthalmologist may use special binoculars to check the integrity of the pupil and its reactions to light, lens, retina and optic nerve. . What are the medical conditions that can be investigated by an eye exam?

Health problems that can be detected by an eye exam



High blood pressure occurs when the force of blood flow is too great for the walls of the arteries. This condition can damage the major vessels responsible for delivering blood to the eye, which can lead to bleeding inside the eye, blurred vision, swelling, swelling, blood clots, lesions optic nerve or even blood clots in the retina which may be associated with loss of vision.

An ophthalmologist can examine blood vessels in the eye wall and detect high blood pressure and even diabetes without having to use a standard blood pressure monitor.

The size ratio of arterioles to arterioles in the blood retina is usually about two or three times greater. If the arteries are much smaller than the arterioles, or if the arteriole is very large and dilated, this may indicate high blood pressure or cardiovascular risk factors.

In some cases, the patient may not know they have high blood pressure, which may not give any physical signs or symptoms, but even then, it can lead to other heart problems such as angina. chest and strokes. eye exam to refer the ophthalmologist to this problem.

In some cases, the doctor notices a blood clot in the eye resulting from a clot in the carotid artery, which is the main artery that supplies blood to the head and neck, or it may be caused by a blood clot in the heart.

Arterial clots occur when they cross an artery and lodge in tiny blood vessels or in organs such as the brain or retina. This condition causes a blood vessel to become blocked or blocked, which can lead to tissue damage, blood clots, blindness, or even death.



Diabetes is one of the diseases that can be detected by a routine eye exam. However, the slow progression of diabetes symptoms can often prevent a prompt diagnosis.

High blood sugar can cause several problems with the tiny blood vessels in the eye. In this case, the patient could be at risk of developing diabetic retinopathy, which in turn could lead to blindness and heart and kidney problems. Of course, diabetes is closely linked to heart disease.

Blindness due to diabetes or heart problems can be avoided by following prevention and patient care advice. Where a simple eye examination can help the patient become aware of these problems early and attempt to start appropriate treatment.


Not only is heart disease the health condition that a simple eye exam can detect, but it can also detect systemic inflammatory diseases that can lead to rheumatism and inflammation in various organs and parts of the body. These various diseases can lead to inflammation of the eyes and lead to pain, redness and loss of vision.

For example, dry eyes can indicate many of these health conditions. If these symptoms are neglected, especially if they get worse, they can damage the pupil, which is the transparent convex part at the front of the eye that needs constant hydration.

In the case of anemia, especially in the chronic or acute condition, the color of the inner eyelid is sometimes white or even yellow, especially when associated with other liver-related health problems.
