Early symptoms of eye cancer such as hard lumps or ulcers on the eyelids that are indistinct, bleed easily, and do not heal easily, and repeatedly and gradually increase in size, require suspicion as to whether there is cancer in the eyelids. There are also cancers in the fundus of the eye, the more common ones being retinal melanoma, which can cause vision changes and visual field changes and must be ruled out by a detailed fundus examination. There is also a more common congenital eye cancer, retinoblastoma, which is a genetic disease. Families with a family history of this disease should pay special attention to this child. If the child has this problem, he or she may have poor vision or may not be able to see, and may be found to have a white pupil, which means that the pupil reflects yellowish-white light, not the normal transparent state.
