Etymology: Ophthalmodynia is a medical coinage assembled from two Greek elements: "ophthalmo-", from "ophthalmós", meaning "eye", and "-odynia", from "odyne", meaning "pain". The first of these has a traceable ancestry running back through Ancient Greek "óps" (face, eye) to a very old root, and the Greek "ophthalmós" itself was formed from "thálamos", a word for an inner chamber, a reference to the eye as a sort of hollow room. The second element is the one doing the real work here, as "-odynia" is the standard medical suffix for pain in a particular body part, so the word simply means eye pain. The term was built in English from these classical parts, not inherited from Greek or Latin speakers, who had no need for a precise name of this kind. That makes it a learned formation of the modern medical vocabulary, where Greek roots were combined to name specific conditions with clinical precision. Other words in the same family, such as "otodynia" for ear pain or "cephalodynia" for head pain, follow the identical pattern.
