Etymology: Vitreoretinal is a plain technical compound, built from two parts that are each well established in medical vocabulary. The first part, "vitreo-", comes from the Latin "vitreus", meaning "glassy" or "made of glass", the same root that gives English "vitreous" and "vitrify". In the eye, the vitreous is the clear, jelly-like substance that fills the space between the lens and the retina, and its name refers to its glassy transparency. The second part, "retinal", is the adjective from "retina", the light-sensitive layer at the back of the eye. That name comes from the Latin "rete", meaning "net", a reference to the fine network of nerve fibres and blood vessels visible in it. Put together, the compound means "relating to both the vitreous and the retina", describing the boundary and interaction between the two layers, which is why it is used in discussing conditions such as vitreoretinal surgery or disorders at the junction of the gel and the light-sensing tissue.
