What term describes the clear gel filling inside the eye?

The term that describes the clear gel filling inside the eye is vitreous gel. This gel-like substance occupies the space between the lens and the retina, contributing to the eye's shape and providing support to the retina. The vitreous humor plays an important role in maintaining intraocular pressure and helps in the proper functioning of the eye.

Unlike the aqueous humor, which is a watery fluid found in the anterior chamber of the eye (located between the cornea and the lens), the vitreous gel has a thicker consistency that is crucial for the structural integrity of the eye. The corneal gel is not a recognized term in ophthalmology; rather, it could refer to the corneal stroma or other components of the cornea. Retinal fluid typically refers to any fluid that may accumulate beneath the retina in certain pathological conditions and does not describe the normal gel-like fill of the interior of the eye. Thus, the choice of vitreous gel accurately captures the description of the substance within the eyeball's interior.
