All malignancies involving the eye, eyelid, orbit, and tear, or lacrimal, glands are managed by ocular oncology, or eye cancer, services. Some of them are benign, while others are cancerous and aggressive. The most effective approaches to prevent and treat eye cancers are investigated in ocular oncology research. On the eyelid, orbit, cornea, conjunctiva, iris, retina, or optic nerve, eye tumours can develop as a primary or metastatic tumour. Ocular oncology research, often known as eye cancer research, focuses on the best ways to prevent and treat eye cancer.
