Generally speaking, retinoblastoma can be divided into several stages. At the beginning, retinoblastoma grows in the eye, often resulting in mydriasis or strabismus due to visual impairment.

Second: as the tumor grows gradually, the volume of the tumor increases, and the swelling of the eye increases, the intraocular pressure will rise, which will cause glaucoma, and patients will have headache, nausea, vomiting and other symptoms. The patient's eyeball wall elasticity is bigger, the long-term high intraocular pressure will cause the eyeball wall to expand, forms the special so-called "bull's eye" appearance.

Third: when the tumor occurs outside the eye, the tumor will penetrate the sclera into the orbit, leading to exophthalmos. There may also cause corneal swelling or perforation, corneal growth outside the eyeball, or even protrude outside the eyelid, grow into a huge tumor. Retinoblastoma can also metastasize to the whole body.
