[건강이 최고] Mole on the eye, such as conjunctival nevus, nevus of Ota, and pterygium, is a type of disease
A mole on the eye means that the melanocytes in the tissue are activated and appear black or dark, like a mole on the skin.
Although it is a kind of eye disease, there is no harm to the body, so it is usually removed for cosmetic purposes. Representative diseases include conjunctival nevus, nevus of Ota, and wing wings. Because the cause, location, and treatment are different, it is necessary to consult with a specialist for treatment.

Conjunctival nevus is a mole on the epithelial layer of the conjunctiva that covers the white of the eye. It spreads widely over the white of the eye and appears pale yellow or brown.
Treatment is not necessary when it does not affect eye function, but when it becomes a cosmetic problem, laser treatment, drug treatment, or surgery is required. Daily life is possible immediately after removal, and UV rays should be blocked and eyes should not be rubbed until recovery.
Rarely, there are times when it deteriorates into malignancy, and at this time, surgical resection and histological examination may be required depending on symptoms such as shape, size, and color change.

Ota nevus differs from conjunctival nevus in the location of the spot. It is a mole on the sclera, which is the inside of the white of the eye, and the conjunctiva covers the birthmark and looks blue. There is no heredity, and surgical treatment is also performed for cosmetic reasons.
Even if you remove the birthmark on the conjunctiva, the conjunctival tissue is regenerated and can be treated cleanly, but the nevus of Ota is more difficult to remove because the pigment is located in the inner sclera.
There is no need for early treatment, and surgery can be performed after the age of 6, when the eyeball is fully grown. However, since general anesthesia is required at a young age, it is better to perform surgery after an adult who can proceed with surgery after local anesthesia.
Pterygium. Provided by Kim’s Eye Hospital
Pterygium, also called pterygium, is a disease in which the black pupil turns white in a triangular shape due to the proliferation of fibrovascular tissue from the white of the pupil toward the cornea.
The prevalence usually increases with age, and it occurs more often in men than in women. Although the exact cause is not known, it is assumed that strong ultraviolet rays are the main cause, as it occurs frequently in people who frequent outdoor activities.
In the early stages, there are no symptoms, but as the size increases, symptoms such as foreign body sensation, pain, redness, and sore eyes may appear. If the size is too large, surgery is required, and the surgery itself is not difficult, but if it is performed before the age of 60, the recurrence rate is high at 40-50%. Therefore, it is better to carefully decide the timing of surgery according to the degree of corneal invasion.
In the case of conjunctival nevus and wing wings, ultraviolet rays are considered one of the main causes, so it is good to wear sunglasses and a hat when going out. In particular, in the case of wing wings, if the symptoms become severe, it can cause visual impairment by covering the pupil.
A specialist at the Corneal Center of Cha Heung-won Eye Hospital said, “The general opinion is that a mole on the eye is a type of pigmentation and does not cause a special eye disease. Therefore, it is better to receive an accurate diagnosis at the hospital.”
