What is the name of the clear, jelly-like substance that fills the eye cavity behind the lens?

The jelly-like substance that fills the eye cavity behind the lens is referred to as vitreous humor. This gel-like material is crucial for maintaining the shape of the eye and providing support to the retina, which is necessary for proper vision. Vitreous humor is composed mostly of water but also contains collagen and hyaluronic acid, contributing to its gel-like consistency.

Aqueous humor, while also an important fluid in the eye, is found in the anterior chamber between the cornea and the lens, and is responsible for maintaining intraocular pressure and providing nutrients to the avascular structures of the eye, such as the lens and cornea. Corneal fluid and intraocular fluid are not standard terminologies in ocular anatomy and do not represent specific components found within the eye.

Understanding the specific roles and locations of these eye components is essential for recognizing their contributions to overall eye health and function.
