The ocular ciliary epithelium is a specialized tissue located in the eye that plays a crucial role in the production and maintenance of the aqueous humor, a clear fluid that helps maintain the shape of the eye and provides nutrients to the surrounding tissues. The ciliary epithelium is responsible for producing the aqueous humor through a process called active secretion and is also involved in regulating its composition and pressure within the eye. Research on the ocular ciliary epithelium focuses on understanding its structure, function, and role in ocular diseases such as glaucoma and cataracts. By studying the ciliary epithelium, researchers aim to develop new treatments and therapies for these conditions and improve our overall understanding of ocular physiology.
