Etymology: Retinopathy is a modern medical coinage built from two parts that were each used long before it. The first, "retino-", comes from "retina," itself a New Latin term for the light-sensitive layer at the back of the eye, derived from the Latin "rete," meaning "net," because the layer was thought to resemble a net of fine fibres. The second part, "-pathy," comes from the Greek "pathos," meaning suffering or disease, and appears in many medical words such as "neuropathy" and "cardiomyopathy." Put together, the parts describe exactly what the condition is: suffering or disease of the retina. The word is a technical formation rather than an old folk term, so it does not appear in the classical world, where physicians had no concept of retinal disease as a distinct category. Its meaning is narrow and precise, and it is used by clinicians to name a group of conditions in which damage to the retina, often as a consequence of diabetes or high blood pressure, impairs vision.

Synonyms: eye disease, ocular disease
