Patient Education
Eyelid Disorders
Your eyelids help protect your eyes. When you blink, your eyelids spread moisture over your eyes. Blinking also helps move dirt or other particles off the surface of the eye. You close your eyelids when you see something coming toward your eyes. This can help protect against injuries.
Like most other parts of your body, your eyelids can get infected, inflamed, or even develop cancer. There are also specific eyelid problems, including:
- Eyelids that turn in or out
- Eyelids that droop
- Abnormal blinking or twitching
Treatment of eyelid problems depends on the cause.

Melanoma
Melanoma is the most serious type of skin cancer. Often the first sign of melanoma is a change in the size, shape, color, or feel of a mole. Most melanomas have a black or black-blue area. Melanoma may also appear as a new mole. It may be black, abnormal, or "ugly looking."
Thinking of "ABCDE" can help you remember what to watch for:
- Asymmetry - the shape of one half does not match the other
- Border - the edges are ragged, blurred or irregular
- Color - the color is uneven and may include shades of black, brown and tan
- Diameter - there is a change in size, usually an increase
- Evolving - the mole has changed over the past few weeks or months
Surgery is the first treatment of all stages of melanoma. Other treatments include chemotherapy and radiation, biologic, and targeted therapies. Biologic therapy boosts your body's own ability to fight cancer. Targeted therapy uses substances that attack cancer cells without harming normal cells.
