Origin: A borrowing from Latin. Etymon: Latin nystagmus.

Etymology: < post-classical Latin nystagmus a rapid involuntary movement of the eyeball (F. Boissier de Sauvages Nosologia Methodica (1768)) < ancient Greek νυσταγμός nodding, drowsiness < the base of νυστάζειν to nod, to be sleepy ( < the same Indo-European base as Lithuanian snūsti (stem snūd-) to begin to doze, grow drowsy) + -μος, suffix forming nouns. Compare French nystagmus (1855; attested earlier as nystagme (1814)).In sense 2 apparently after J. J. Plenck Doctrina de Morbis Oculorum (1777) 115, where the intended sense may not be the same. N.E.D. (1907) gives only the pronunciation (nistæ·gmɒ̆s) /nɪˈstæɡməs/.
