Conjunctival tumors
The most common tumors of the conjunctiva in adults are squamous cell carcinoma, malignant melanoma, and lymphoma. The main treatment for these tumors includes surgery. In some cases, your healthcare provider may do Mohs surgery. This method removes very small, thin pieces of tissue. They are then looked at right away under a microscope. If your healthcare provider sees cancer cells, they may remove more tissue. Once the tissue samples are clear of cancer cells, the procedure is done.
If the tumor is large, you may have cryotherapy. Researchers are also studying the use of chemotherapy (chemo) eye drops for people who have conjunctival squamous cell carcinoma. The drops are used after surgery. Researchers are studying the use of chemotherapy for conjunctival melanoma, too. These may be choices when there are tumors in several places on your eye.
Conjunctival lymphomas may be treated with radiation alone, as long as there is no lymphoma anywhere else. Lymphomas that occur inside the eye (intraocular lymphoma) need to be treated with chemotherapy. Surgery is not normally used to treat lymphoma of the eye. But in some cases, your healthcare provider may do a biopsy to confirm intraocular lymphoma.
Tumors in the iris
These are rare, slow-growing tumors. Treatment of these tumors depends on if the tumor is growing. It also depends on if there is any complication from the tumor, such as uncontrolled glaucoma. If you have glaucoma that does not get better with medicine or if the tumor is growing quickly, your healthcare provider may remove your entire eye (enucleation). If the tumor is not growing and the glaucoma can be controlled with medicine, you may need surgery to remove only the tumor. In some cases, you may need radiation.
Choroidal tumors
Melanomas
Choroidal melanomas is a subtype of uveal melanoma. It's also called intraocular melanoma. This is the most common type of eye cancer in adults. The treatment for choroidal melanomas can include thermal destruction (cryotherapy or photocoagulation), radiation, surgery to remove the tumor, or complete removal of your eye. Or you may not have any treatment at all. The choice depends on the size of the tumor, if it's growing, and if you're having symptoms. Talk about each choice with your healthcare provider. Think about all the risks and benefits of each choice. In some cases, you may need chemotherapy.
Nevus
A nevus is a little spot on your eye. It is sometimes called an eye freckle. Nevi (the plural of nevus) are rare and almost never need treatment. Your eye care provider can watch for changes over time. It is rare but choroidal nevi can turn into melanoma. If they do, they are treated as a choroidal melanoma.
Cancers of the eyelid
The most common type of eyelid cancer is basal cell carcinoma. It is most often on the lower lid. Some types of cancer affect eyelid glands, such as the sebaceous gland. Sebaceous carcinoma is the second most common eyelid cancer. Other types are squamous cell carcinoma and cutaneous melanoma. The treatment most often used for cancer of the eyelid is surgery. The goal of surgery is to remove all the cancer. The type of surgery you have depends on the size of the tumor. If you need most of your eyelid removed, your healthcare provider will reconstruct it using plastic surgery. In some cases, you may need radiation. This can kill any cancer cells that may have been left behind.
