Healthy human eyeball

What is 1 white eye, commonly known as white eye kernel, medically called sclera. It is a protective layer containing collagen and elastic fibers, covering the muscles that allow the eyes to rotate in the eye socket. Scleral includes superficial sclera, sclera parenchyma and brownish-black layer. The superficial sclera is rich in blood vessels and prone to pathological changes. There are few deep blood vessels and nerves, so it is not easy to get sick. Scleral is a kind of elastic soft tissue. Without elasticity, it will become hard and people's eyes will be easily deformed. The problem after deformation is myopia of teenagers. The normal sclera should be milky white, or blue if the congenital sclera is thin. Other colors, such as yellow, red, black and white, are abnormal colors, which need attention.

There is a gray ring on the cornea, that is, the thin film on the eyeball, and a layer of gray halo appears around the cornea, which is called the "elderly ring".

The most common causes are hyperthyroidism and hyperthyroidism, which is because the thyroid gland in the neck produces too many hormones in a short time.

Red eye is almost red, which is one of the most common scleral symptoms. It may be caused by allergies and lack of sleep, or it may be a more serious disease signal, such as glaucoma. Acute angle-closure glaucoma will be jealous because of the sudden increase of intraocular pressure.

Sometimes, the spots on the eyes may be completely benign. But according to the American Academy of Ophthalmology, it may also be a reaction to some topical ophthalmic drugs, or it may be a sign of melanoma. The latter is a kind of skin cancer that can be fatal. The early cure rate is high and the late 5-year survival rate is less than 10%.
