ptosis etymology

Etymology:

• From Ancient Greek πτῶσις (ptōsis), "a falling," from πίπτω (piptō), "to fall."

Meaning:

• A drooping of the upper eyelid (blepharoptosis).

Origin:

• Ptosis was first recognized and described by the Greek physician Hippocrates (460-370 BC) in his treatise "On the Affections."
• It is believed that the term "ptosis" was originally used to describe the drooping of the eyelid associated with paralysis of the oculomotor nerve, which controls the muscles that lift the eyelid.
• Over time, the term has come to be used more generally for any drooping of the upper eyelid, regardless of the cause.
