What fills the anterior chamber of the eye?

The anterior chamber of the eye is filled with aqueous humor, a clear fluid that is produced by the ciliary body. This fluid plays a critical role in maintaining intraocular pressure and providing nutrients to the avascular structures of the eye, such as the lens and cornea. Aqueous humor also helps in the removal of metabolic waste from these structures.

The function of aqueous humor is crucial for the overall health of the eye and contributes to its optical properties, ensuring that light can pass through unobstructed. In contrast, blood is not present in the anterior chamber under normal circumstances; its presence could indicate a pathological condition. Vitreous humor, on the other hand, is found in the larger, more posterior vitreous chamber of the eye, while lymph fluid is not involved in eye physiology. Understanding the composition and function of the anterior chamber emphasizes the importance of aqueous humor in eye health and vision.
