As we age, various organs of our body will degenerate to varying degrees, and the eyes are no exception. I believe many people will notice that some elderly people will have white rings around their black eyes, what is the reason for this? Today, I'm going to reveal the truth about this phenomenon for you.
First, we need to understand the structure of the eyeball. The eyeball is made up of the wall of the eyeball, which includes the adventitia, media, and endometrium. The adventitia is made up of the cornea and sclera, the mesometa is made up of the iris, ciliary body, and choroid, and the inner membrane is the retina. And the black eye kernel is actually the iris, which contains many pigments that determine the color of our eyes.
So, what exactly is this white ring? In fact, it is called a corneal annular lesion, which is a degenerative disease that occurs with age. Corneal annular lesions occur mainly in the tissues that surround the cornea, known as the limbus. It usually appears as a white or gray ring that surrounds the kernel of the black eye.
There are many causes of corneal annular lesions, which include genetics, malnutrition, eye infections, eye trauma, etc. In addition, corneal annular lesions may also be associated with some systemic diseases, such as rheumatoid arthritis, hypertension, diabetes, etc. As we age, the tissues of the eyeball gradually degenerate, and the blood vessels in the limbus become fragile and prone to lesions.
So, what are the effects of corneal annular lesions on vision? In general, corneal annular lesions do not have a noticeable effect on vision. However, in some cases, if the corneal annular lesion is severe, it may cause symptoms such as eye pain, blurred vision, etc. Therefore, it is very necessary for the elderly to have regular eye examinations.
In addition to corneal annular lesions, there is also a common eye lesion called cataracts. Cataract is a disease in which the lens is clouded and one of the main causes of vision loss in the elderly. Symptoms of cataracts include blurred vision, fading colors, glare, etc. If left untimely**, it can lead to blindness.
So, how can these eye pathologies be prevented? First of all, we need to maintain good lifestyle habits, such as getting enough sleep, not smoking, and drinking less alcohol. Secondly, it is necessary to pay attention to eye hygiene to avoid eye infections. In addition, regular eye examinations to detect and improve eye diseases in time are also important measures to prevent eye lesions.
In conclusion, the appearance of white rings around the kernel of the dark eyes in the elderly is mainly due to the annular lesions of the cornea. It is a degenerative condition that occurs with age and usually does not have a noticeable effect on vision. However, if the lesion is severe, it may cause symptoms such as eye pain, blurred vision, etc. Therefore, the elderly should have regular eye examinations to prevent the occurrence of ocular lesions.
