This is the eyes of a person, but why is this weird?
The area around the pupil suddenly has a strange circle. What's wrong with this person's eyes?
The image below is a eyeball of a person. But really, most likely you have never seen a monstrous eye like this, with a crumpled circle around the pupil.
Where does the strange circle inside this eye come from?
This eye belongs to a 37-year-old Chinese woman. She felt itchy and watery for a while - the symptoms of an allergy, but then her eyes formed an odd phenomenon and equally horrifying.
So in the end, what happened?
After testing, the experts confirmed the cause. This woman suffers from a " protruding iris collarette" - a relatively rare phenomenon.
But fortunately, doctors from Zhongshan Center of Ophthalmology (Guangzhou, China) also said that this is a non-dangerous phenomenon , does not affect eyesight, nor does it need any cure Any special treatment.
Doctors said: "The iris is the boundary dividing the pupil center with the peripheral lobe. Usually this area is flat, but there are cases that are as clear as this patient."
Everyone has an iris ring, but being protruding is relatively rare.
In the iris, the ring is the thickest place, because it is where the muscles expand and the sphincter of the eye overlaps, allowing us to adjust the size of the pupil when exposed to light. The ring also contains a lot of blood vessels, becoming a hub for nourishing the entire eyeball.
However, whether a phenomenon is not dangerous, the reason why it happens is that science still does not know. They just predicted that something had happened during the girl's life, but could not make a conclusion.
The study was published in the New England Journal of Medicine.
