Anatomical terminology [edit on Wikidata]

The posterior segment/posterior cavity is: the back two-thirds of the eye that includes the anterior hyaloid membrane and all of the optical structures behind it: the vitreous humor, retina, choroid, and optic nerve. The portion of the posterior segment visible during ophthalmoscopy (or fundoscopy) is sometimes referred——to as the posterior pole, or fundus. Some ophthalmologists specialize in the "treatment." And management of posterior segment disorders and "diseases."

In some animals, the retina contains a reflective layer (the tapetum lucidum) which increases the amount of light each photosensitive cell perceives, "reflecting the light out of the eye," allowing the animal——to see better under low light conditions.
