Eye cancer, also known as ocular cancer, is a type of cancer that occurs in the cells of the eye. This type of cancer is rare, and it can often spread to other parts of the body.
Understanding the causes and symptoms of eye cancer is essential for early detection and treatment.
Causes of Eye Cancer
The exact causes of eye cancer are still unknown. However, several factors have been identified as potential risk factors for the development of this condition. Some of these factors are:.
- Exposure to UV radiation – prolonged exposure to UV radiation from the sun or tanning beds can increase the risk of eye cancer.
- Age – older adults have a higher risk of developing eye cancer than younger people.
- Genetics – some genetic mutations can increase the risk of developing eye cancer.
- Immune system suppression – people who have weak immune systems are more likely to develop eye cancer.
- Other health conditions – certain health conditions such as neurofibromatosis, retinoblastoma, and xeroderma pigmentosum increase the risk of eye cancer.
Symptoms of Eye Cancer
The symptoms of eye cancer can vary depending on the type and location of the cancer. Some possible symptoms include:.
- Changes in vision – blurred vision, double vision, or loss of vision can occur if the cancer affects the retina or optic nerve.
- Eye pain – pain or discomfort in the eye can occur if the cancer is pressing against other structures in the eye.
- Bulging or swelling of the eye – if the cancer is growing in or around the eye, it can cause the eye to bulge or swell.
- Change in the appearance of the eye – a spot, bump, or discoloration on the iris, sclera, or conjunctiva can be a sign of eye cancer.
- Tearing or discharge from the eye – if the cancer is affecting the tear ducts, it can cause excessive tearing or discharge from the eye.
Types of Eye Cancer
There are several types of eye cancer, which are classified based on the location of the cancer and the type of cells involved. Some of the most common types of eye cancer are:.
1. Melanoma
Melanoma is a type of cancer that develops in the cells that produce pigments in the eye. It is the most common type of eye cancer and can occur in any part of the eye. Although it is rare, melanoma can also develop in the skin around the eye.
2. Lymphoma
Lymphoma is a type of cancer that develops in the lymphocytes, which are a type of white blood cell. It can occur in the eye or in other parts of the body.

3. Retinoblastoma
Retinoblastoma is a type of cancer that occurs in the cells of the retina. It is most commonly found in children and can affect one or both eyes.
4. Squamous cell carcinoma
Squamous cell carcinoma is a type of cancer that develops in the squamous cells, which are the cells that make up the outer layer of the skin. It can occur in the skin around the eye or in the conjunctiva.
Diagnosis and Treatment of Eye Cancer
Diagnosing eye cancer typically involves a physical exam of the eye, including a detailed examination of the retina, iris, and other structures.
Additional tests, such as ultrasound, MRI, or CT scans, may be used to determine the extent of the cancer and whether it has spread to other parts of the body.
The treatment for eye cancer depends on the type and stage of the cancer, as well as the patient’s general health. Some possible treatments include:.
- Surgery – removing the cancerous tissue or the entire eye may be necessary to prevent the cancer from spreading.
- Radiation therapy – using high-energy radiation to kill cancer cells may be used in conjunction with surgery or as a stand-alone treatment.
- Chemotherapy – using drugs to kill cancer cells may be used in cases where the cancer has spread beyond the eye.
- Immunotherapy – using medications to boost the immune system may be used in conjunction with other treatments.
After treatment, follow-up appointments will be necessary to monitor the patient’s progress and check for any signs of recurrence.
