Eyes are the most sensitive part of our body. A person needs to give additional attention to maintain eye health and prevent any eye problems. Eye diseases affect not only the smooth functioning of the eye but it also hampers your vision. Eye tumors can be diagnosed through various eye examination and tests that also include CT scan, MRI and Ultrasound tests.
Some of the most common types of Eye Tumors that affect the eyes are given as under:
- Conjunctival Tumors: These are malignant cancers that grow on the outer surface of the eye. The most common of them are squamous cell carcinoma, malignant melanoma, and lymphoma. These can be treated through surgery, cryotherapy or chemotherapy.
- Eyelid Tumors: Tumors of the eyelid may be benign cysts, inflammation, or malignant skin cancers. The most common is the basal cell carcinoma that can be removed with surgery. Additional cryotherapy and radiation therapy can also be used sometimes, after surgery.
- Iris Tumors: Tumors can also grow within and behind the iris. Most of the pigmented iris tumors do not grow and if they do, then treatments like surgery or radiation plaque therapy or enucleation.
- Melanocytoma: It is a slow-growing tumor that is found on the surface of the optic disc. It is probably present at birth and typically, there are no symptoms. In the majority of cases, close observation is recommended. If malignant transformation does occur, enucleation, may be considered.
- Orbital Tumors: Tumors and inflammations can also occur behind the eye that push the eye forward causing bulging of the eyes called proptosis, caused due to thyroid eye disease and lymphoid tumors. Other tumors include hemangiomas tumors, lachrymal gland tumors, and growths that extend from the sinuses into the orbit.
According to a latest research published in Science Daily, ‘a specific small segment of RNA can play a key role in the growth of a type of malignant childhood eye tumor called retinoblastoma. The tumor is associated with mutations of a protein called Rb (retinoblastoma protein). Dysfunctional Rb is also involved with other types of cancers, including lung, brain, breast and bone.’
