What is the approximate volume of the vitreous?

The vitreous body, a clear gel-like substance that fills the space in the eye between the lens and the retina, plays a critical role in maintaining the eye's shape and optical properties. The approximate volume of the vitreous humor in an adult human eye is around 4 milliliters. This volume can vary slightly among individuals, but it generally falls within this range.

The vitreous body provides support to the retina and acts as a shock absorber, protecting delicate structures from sudden movements or impacts. Its composition is primarily water, along with collagen, hyaluronic acid, and various other substances that contribute to its gel-like consistency.

Understanding the approximate volume of the vitreous is relevant in the context of various ocular conditions and surgical procedures, such as vitrectomy, where the vitreous is removed for treatment of retinal diseases. Knowing this volume helps in guiding surgical approaches and understanding the potential impacts on vision and eye health.
