Retinoblastoma

Tumor - retina; Cancer - retina; Eye cancer - retinoblastoma

Retinoblastoma is a rare eye tumor that usually occurs in children. It is a malignant (cancerous) tumor of the part of the eye called the retina.

Eye

The eye is the organ of sight, a nearly spherical hollow globe filled with fluids (humors). The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle layer (choroid, ciliary body and the iris) is vascular. The innermost layer (the retina) is nervous or sensory. The fluids in the eye are divided by the lens into the vitreous humor (behind the lens) and the aqueous humor (in front of the lens). The lens itself is flexible and suspended by ligaments which allow it to change shape to focus light on the retina, which is composed of sensory neurons.
