Inocular

Inocular is an adjective formed from the Latin in- meaning "in" and ocular meaning "of the eye." It is exceedingly rare in modern English and is not a standard term in ophthalmology or anatomy. In contemporary medical writing, the sense most often conveyed by this root is expressed with intraocular (inside the eyeball) or binocular (involving two eyes).

Because of its rarity, inocular can appear as a typographical variant or a historical usage rather than a current technical term. When encountered in older texts, it may describe aspects related to the eye, but readers should interpret it with caution and rely on more common terminology.

Etymology and history: The form likely derives from Latin in- plus oculus, and it appears sporadically in 19th- and early 20th-century writings. It has largely fallen out of use and is considered obsolete in modern ophthalmology.
