Ophthalmology Flashcards
sclera
outer protective layer of the eye; the portion seen on the anterior portion of the eyeball is referred to as the white of eye
cornea
transparent anterior part of the sclera, which is anterior to aqueous humor and lies over the iris. It allows the light rays to enter the eye
