Vitreous Fluid - The jelly-like fluid that fills the main part of the eye, between the lens and the retina. It’s clear so as to give light rays an unobstructed path to the retina, and to keep that clarity, it contains phagocytes, cells which ingest and destroy foreign matter.

Vitreous Humor - The transparent gel that fills the space inside the eye behind the lens and in front of the retina.

Sclera - (SKLEH-ruh) The white outer layer of the eye, which is tough and protective. It joins smoothly with the cornea and continues in the back of the eye, connecting with the sheath that covers the optic nerve.

Scotopic Pupil Size - The size of the pupil in dim lighting conditions, as in moonlight.

Endothelium is the inner layer of cells on the inside surface of the cornea.
