[이데일리 이순용 기자] A mole on the eye means that the melanin cells in the tissue are activated and look black or dark, like a mole on the skin. Although it is a type of eye disease, it is harmless to the body, so it is usually removed for cosmetic purposes. Representative diseases include conjunctival nevus, nevus of ota, and wing wings. Causes, locations, and treatments are different, so they must be treated through consultation with experts.
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. In many cases, it does not affect eye function, so medical treatment is not required, but if it becomes a cosmetic problem, it is treated with laser, drug treatment, or surgery. Daily life is possible immediately following removal, and UV rays should be blocked and eyes should not be rubbed until recovery. In rare cases, it develops into malignancy, and at this time, surgical resection and histological examination may be required depending on symptoms such as changes in shape, size, and color.
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 the conjunctival nevus is removed, the conjunctival tissue is regenerated and can be treated cleanly, but Ota nevus is more complicated to remove because the pigment is located in the inner sclera. Early treatment is not necessary, and surgery can be performed following the age of 6, when the eyeball is fully grown. However, since general anesthesia must be performed at a young age, it is better to perform surgery following an adult who can perform surgery following local anesthesia.
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, strong ultraviolet rays are presumed to be the main cause, as it occurs frequently in people who frequent outdoor activities. Initially, there are no symptoms, but as the size increases, foreign body sensation, pain, redness, and sore eyes may appear. If the size becomes too large, surgery is required, and the surgery itself is not difficult, but if surgery is performed before the age of 60, the recurrence rate is high at 40-50%. Therefore, it is recommended to carefully determine the timing of surgery according to the degree of corneal invasion.
In the case of conjunctival nevus and pterygium, ultraviolet rays are 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, so regular checkups and treatment are important if there are many outdoor activities or symptoms of wing wings appear.
Cha Heung-won, a specialist at the Corneal Center of Kim’s Eye Hospital, said, “It is common opinion that moles on the eye are a type of pigmentation and do not cause any special eye disease. Because there is a possibility that it may develop, it is better to visit the hospital and receive an accurate diagnosis.”
