Question

Function of aqueous humor is
A. Nutrition to lens
B. Maintain intraocular pressure
C. Preparation of image
D. Both A and B

Answer 1

Hint: The aqueous humor is the small, transparent, watery fluid covering both the eye's anterior and posterior chambers. It is formed in the posterior chamber of the eye by the ciliary processes.

Complete Answer:
- The aqueous chamber is the area between the cornea and the lens and contains a thin watery fluid called aqueous humor. The lens-retina area is called the vitreous chamber and is filled with a translucent gel called vitreous humor.
- The aqueous humor gives the eye its form by providing nutrients such as amino acids and glucose to nourish the cornea and the lens. It is also the key to preserving and maintaining eye health.
- It plays an important role in the maintenance of the shape of the eyeball and internal ailments along with production of intraocular pressure. Intraocular pressure is the intraocular fluid pressure inside the eyeball.
- The retina is a sensitive membrane that has large numbers of light-sensitive cells. When illuminated, the light-sensitive cells get triggered and produce electrical signals. The signals are transmitted via the optic nerves into the brain. The brain interprets these signals, and eventually the information is interpreted so that we perceive things as they are.

Thus, the correct answer is option D, i.e., Both A and B.

Note: Small changes in the outflow or production of aqueous humor can have a significant effect on the intraocular pressure and the image quality that the eye generates. If the intraocular pressure is increased, it can lead to glaucoma which is one of the leading causes of vision loss.
