Eye cancer can be a devastating diagnosis, and the effects on the eye can vary depending on the type of cancer.
If the eye cancer is ocular melanoma, the most common type, it will typically cause a dark spot or discoloration on the colored part of the eye, known as the iris. The spot may grow larger over time, and may be accompanied by blurred vision, flashes of light, or a change in the size or shape of the pupil. If the melanoma is left untreated, it can grow bigger and spread to other parts of the eye, eventually leading to vision loss.
If the eye cancer is retinoblastoma, the second most common type, it will usually cause a white or yellow-tinted mass in the back of the eye. This mass can grow quickly, and vision loss may be sudden. In some cases, the eye may become red or swollen, and the retina may become detached due to the pressure of the tumor. If left untreated, the tumor can spread to the optic nerve and other parts of the eye, leading to vision loss.
In either case, early diagnosis and treatment is key to preserving vision. Treatment options may include radiation therapy, chemotherapy, cryotherapy, and/or surgical removal of the tumor. In some cases, the entire eye may need to be removed to prevent the spread of cancer.
No matter the type of eye cancer, it is important to seek medical attention as soon as possible. An early diagnosis can make a huge difference in preserving vision and preventing the spread of cancer.
