"ciliary body"の定義と意味

What is "ciliary body"?

The ciliary body is a component of the eye located behind the iris. It is a singular structure that plays a crucial role in vision. The ciliary body consists of muscles that control the shape of the lens, enabling the eye to focus on objects at various distances. Additionally, it produces the aqueous humor, a fluid that nourishes the eye and helps maintain its shape. The ciliary body's ability to adjust the lens and regulate fluid contributes to clear vision and optimal intraocular pressure.
