- Spasms and involuntary eyelid twitching can be caused by stress, nutritional imbalance, or excessive caffeine consumption.
- Dark circles can be a sign of water retention.
The eyes do not only allow us to see. These are reflections of the internal state of the body. These eyeballs clearly tell us if we are in good health or if we are suffering from unexpected health problems. Several technologies have recently been developed to look for a condition through the eye. This is the case of a smartphone application developed by researchers at the University of California, San Diego (USA). The latter, thanks to a selfie, measures the size of the patient’s pupil to detect symptoms of disease or neurological disorders in the eyes.
But according to Barbara Pierscionek, a professor at Anglia Ruskin University in England, it is possible to tell if we have a pathology by looking at our eyes and carefully analyzing them. In an article published on The conversationthe researcher revealed the signs to watch out for and take seriously.
If the whites of the eye turn yellow, it is usually jaundice or liver dysfunction. This yellowing of the eye is caused by an excessive build-up of bilirubin, a yellow pigment, in the blood.
The pupil no longer dilates properly
When exposed to light, the pupil immediately contracts and dilates. If this pupillary reflex occurs slowly or late, it can be a sign of Alzheimer’s disease.
A red spot in the white of the eye
Bleeding in the eye, i.e. a “burst” blood vessel in the eye, can indicate high blood pressure, diabetes or blood clotting disorders.
A white circle around the colored part of the eye
With age, a clearer arc may appear at the periphery of the cornea, known as the ‘arcus senilis’. However, it can also be caused by a build-up of cholesterol. This sign can clearly be associated with excess cholesterol, but not necessarily with hypercholesterolemia.
More and more protruding eyes
Bulging eyes can be the result of an infection, injury, inflammation, or a tumor behind the eye. Another cause: a problem with the thyroid gland, causing swelling.
A lump on the eyelid
A chalazion, a red lump on the eyelid, is caused by a blocked oil gland.
