Nevus of Ota, also called nevus fuscoceruleus ophthalmomaxillaris, is a type of birthmark that appears bluish-gray or brown in color. It usually affects the skin around the eye but can also appear on the forehead, cheek, and nose.

It is caused by the accumulation of melanin in the skin and can be present at birth or develop during early childhood. While it is generally harmless, it is considered a cosmetic concern for some people and can be treated with laser therapy. People with Nevus of Ota should be monitored regularly for any changes or growth.

The exact cause of Nevus of Ota is unknown but it is believed to occur due to an excess production and accumulation of melanin pigment in the skin, which may be triggered by hormonal changes, genetic factors, or exposure to ultraviolet radiation.

Laser treatment for Nevus of Ota involves using a high-energy laser to target the pigmented skin cells in the affected area. The laser emits a specific wavelength of light that is absorbed by the pigment cells, causing them to break down and be absorbed by the body’s natural processes.

During a laser treatment to treat Nevus of Ota, the patient will be given topical or local anesthesia to minimize discomfort during the procedure.

The laser device will emit a beam of light that targets the pigmented cells in the skin, breaking them down and causing them to be absorbed by the body’s immune system.

After a laser treatment to treat Nevus of Ota, one can typically expect some redness and swelling in the treated area.

The skin may also feel tender, and there may be some mild bruising.

Over the next few days, the treated skin may form scabs or start to flake off. In some cases, the skin may appear darker or lighter than the surrounding skin, but this usually resolves with time. It is important to follow proper after-care instructions to ensure optimal healing and to minimize the risk of complications.
