From diabetes to Alzheimer’s and brain tumor and Hypertension, the eyes offer a window into the body that helps doctors see different conditions.
Why does it look as comfortable eye disease that is non-invasive – no cutting of the skin, bleeding, swallowing a camera, or something like that.
Unless something nefarious is suspected, your eyes just peek through Ophthalmologists, Optometrists, or in some cases a doctor. You can use the Ophthalmoscope (basically a strong magnifying glass with light), and may ask you to take a few drops to dilate your pupils.
Literally like windows
The key to why the eye as an excellent diagnostic tool, which you can not only see, but also the doctor can look through the lens and cornea clear, the retina. And here, in the back of the eye, is the one place in the body where blood vessels without first being tested to cut through the skin. And if you think a person can tell a lot by looking at the eyes, wait till you see the blood vessels.
It may help to think of a building with two windows only. With this window you can see some pipe (some of which may be leaking) or you can see some junk lying around. And put it all together, you can get an idea (or specific enough) general idea of how the building is kept.
Similarly, the blood vessels at the back of the eye may offer important clues to the health of the body and help physicians identify some chronic systemic diseases.
When peering into your eyes, Ophthalmologists are very likely to see the branching network of veins and arteries – the blood vessels become more vivid and more dense, while the arteries are thin and have a bright red color.
Some changes in the appearance of thin webbing artery showed that the patient may have arteriosclerosis (hardening of the arteries) or Hypertension (high blood pressure).
There are also suggestions that the small plaque deposits in the eye may indicate cholesterol build-up elsewhere in the body.
Similarly, minor bleeding (hemorrhage) area may indicate that the patient has diabetes – vascular damage is a typical result of diabetes. There have been reports of patients have no idea that they have diabetes, until he is tested in this way.
Some eye signs also indicate a brain tumor. So, the doctor may look for an optical disk swelling (known as papilloedema,) which may be a result of inflammation of the eye pressing root.
Apart from diseases and conditions, sickle cell anemia, leukemia, and brain aneurisms also left their mark on the eye.
At the cutting edge
U.S. researchers experimenting with cutting-edge technology that helps them detect beta amyloid protein in the lens of the eye using short light pulses. Beta amyloid protein is a sign of Alzheimer’s. Hope is that this test could help early diagnosis of this devastating neurological disease.
Preliminary research suggests that a deadly form of malaria known as cerebral malaria can be evaluated by eye. The researchers say that the left cerebral malaria opaque spots on the retina and whiten several arteries at the back of the eye.
The way in which the eye movement tracking could be used to diagnose a variety of psychological conditions. Research conducted at the University of Illinois are trying to find the pattern of eye movements that can help diagnose conditions such as schizophrenia.
Connected to the body
The fact that so many sick leave footprints in your eyes, makes it very important that the eye is connected to other parts of the body.
