Anatomical terminology [edit on Wikidata]

Thesclera andcornea form thefibrous tunic of the bulb of the eye; the sclera is opaque, and constitutes the posterior five-sixths of thetunic; the cornea is transparent, and forms the anterior sixth.

The term "corneosclera" is also used to describe the sclera and cornea together.^[1]
