👉 The iii fluid, also known as intraocular fluid (IOP), is a clear, colorless liquid that fills the anterior and posterior chambers of the eye, as well as the vitreous body within the eye's posterior chamber. This fluid plays a critical role in maintaining intraocular pressure (IOP), which is essential for the proper functioning of the eye, including nourishing the cornea and lens, removing waste products, and ensuring the eye's shape remains stable. An imbalance between the production and drainage of this fluid can lead to conditions such as glaucoma, where elevated IOP can damage the optic nerve and potentially result in vision loss.
