What is nevus Ota?
Nevus ota is a skin lesion blue or gray pigmentation that occurs on the face. The condition is usually innate, which means it occurs before or during birth. In some cases, OTA may not occur in the eye, which usually indicates the presence of eye disease. The condition passes through several other terms, including congenital non -fuscoceruleus ophthalmomaxillaris, melanosis bulbi, oculodermal melanocytosis and oculomucodermal melanocytosis. Nevus Ota is referred to as Nevi Ota in the plural.
m.t. Ota, known as Mokutaro Kinoshita, was a Japanese doctor who first described the situation in 1939 and is therefore named after him. It does not develop from melanocytes that are cells in the lower layer of the epidermis or outer layer of the skin. Melanocytes are responsible for the production of melanin that provides the skin of its color. Therefore, there is no OTA when hyperpigmentation or abnormally increased color occurs. Cause this condition remains unknown even though it is known to be OzkyIt most often ties in Japan, where it develops it with one of each 2,000 people.
Nevus OTA gradually increases and darker color as time goes. Nevi -related skin can be a sign of melanoma that occurs when melanocytes become malignant and cause skin cancer. Melanoma may also occur in the eyes if it carries hyperpigmentation. However, glaucoma is most often associated with OTA related to the eye. Damage to the optical nerve caused by this eye disorder can lead to blindness.
Standard, ideal treatment for Nevus OTA is pulse laser surgery with switches of Q. Also known as the formation of a giant pulse, involves the transformation of lasers into pulse output rays focused on dermal melanocytes. Extensive acceptance of laser surgery with switched Q is attributed to its success, which is not less than 90 percent. We are myually served in four to eight treatments.
q switched laser surgery forNevus Ota has replaced older surgical treatment, such as cryotherapy, which includes the application of cold to destroy the abnormalities of tissue and dermabraze, which includes wear of skin defects with tools and agents and lasers. Some people use make -up to cover the defect, although it is more cosmetic than medicinal solution. After dermal treatment, no subsequent meetings are usually required and the forecast is usually excellent. However, people with eye events might want to regularly visit their ophthalmologists to make sure that the state does not change into glaucoma or melanoma.
