Vitreous cavity

The **vitreous cavity** is an anatomical space in the eye located between the lens and the retina. It is filled with a clear, gel-like substance called **vitreous humor** or **vitreous body**, which makes up about 80% of the volume of the eyeball. The primary functions of this cavity are to maintain the spherical shape of the eye, provide a clear medium for light to pass through to reach the retina, and absorb shocks that could otherwise damage internal ocular structures. The vitreous humor itself consists mostly of water with small amounts of collagen and other proteins[1][3][5][6]. While important in ophthalmology as a site affected by various diseases or surgical interventions (such as vitrectomy), it is not considered a molecular therapeutic target like receptors or enzymes. Key points: - The term "vitreous cavity" refers to an anatomical compartment rather than a specific molecule or receptor. - It does not have molecular targets nor does it interact directly with drugs in a way typical for pharmacological targets. - Pathologies involving this space include retinal detachment and vitreoretinal disorders[5]. Because "Vitreous cavity" is an anatomical structure—not a molecule/receptor/therapeutic target—this entry should be flagged as incorrect if you are seeking information on druggable biological targets.
