Ocular tumours are tumours that grow inside the eye. They can be either malignant or benign. Tumours are masses that grow from groups of cells that grow and multiply abnormally. Ocular tumours can appear in the eyelid, in the orbit, or on the surface of the eye.
What are the causes of Ocular Tumours?
Eye tumours are usually secondary tumours that are caused by cancers that have already developed in other parts of the body, particularly the lungs, breast and bowel. However, several types of cancer arise in the eye itself, such as squamous cell carcinoma, lymphoma, eye melanoma - the most common ocular cancer in adults - and retinoblastoma in children.
The cause of ocular tumours is often unclear. Some factors are believed to make the development of a tumour more likely. Eye melanoma, for example, is associated with overexposure to sunlight, unusually shaped moles, white skin and blue or grey eyes, and use of sunbeds with UV light.
What are the symptoms of eye cancer?
Eye cancer can be easy to miss as sometimes there are not any obvious symptoms. It is often only be detected during a routine eye test.
Symptoms of ocular cancer include:
- 1. Blurred vision
- 2. Bulging in one eye
- 3. A visible lump in the eyelid or eye that grows
- 4. A dark patch in one eye
- 5. Partial loss of vision
- 6. Distorted vision sometimes with wavy lines, flashes of light or shadows
- 7. Pain in the eye or surrounding area
These symptoms in themselves can also indicate other eye condition so they do not necessarily indicate cancer. If you notice any unusual symptoms in your eyes, it is vital to make an appointment with an ophthalmologist as soon as possible.
