Intraocular fluid is a type of bodily fluid that is found inside the eye. There are a few different terms that can be used as a synonym for this substance, including aqueous humor, vitreous humor, and ocular fluid. Aqueous humor is the clear, watery fluid that is found in the front chamber of the eye. Vitreous humor is the thicker, gel-like substance that fills the back chamber of the eye. Ocular fluid is a more general term that can refer to any of the fluids found within the eye. All of these terms refer to the essential fluids that help to maintain the shape and function of the eye, while also providing nutrients and removing waste materials.
