Vitreous chamber
The vitreous chamber is the largest of the three chambers in the eye and is located behind the lens and in front of the optic nerve. The vitreous chamber is located in the posterior cavity of the eye. This chamber is occupied with a thick, clear gel-like substance called the vitreous humor.
Structure
Within the vertebrate eye, there are considered to be three chambers: anterior, posterior, and vitreous. The eye can also be classified as having two cavities: anterior and posterior. Both the anterior and posterior chambers are located within the anterior cavity, while the vitreous chamber is located in the posterior cavity. The best way to distinguish between the two cavities is to use the lens as a dividing point. The vitreous chamber is the largest of the three chambers and is located behind the lens and in front of the optic nerve. Recent research has demonstrated that the volume of the vitreous chamber varies significantly between individuals and is correlated with axial length and refractive status. Eyes with high axial myopia tend to have larger vitreous chamber volumes, whereas eyes with shorter axial length associated with hyperopia generally have smaller volumes. These interindividual differences have raised interest in investigating whether individualized or personalized approaches to intravitreal therapies and vitreoretinal surgeries may provide advantages over a uniform "one-size-fits-all" paradigm, particularly with respect to intraocular drug concentration, dilution effects, and dosing considerations of drugs and gas/siloil implantations. Such questions are currently being evaluated in ongoing clinical and large multicenter studies.The vitreous chamber is filled with a thick, clear gel-like substance called the vitreous humor. The humor plays a crucial role in supporting the posterior side of the lens.
