The ciliary epithelium is a specialized epithelial tissue found in the eye. It consists of two layers: the pigmented epithelium and the non-pigmented epithelium. The primary function of the ciliary epithelium is to produce aqueous humor, a clear fluid that nourishes and maintains the shape of the eye. Research in this area focuses on understanding the mechanisms underlying aqueous humor production, as well as the role of the ciliary epithelium in regulating intraocular pressure. This research is essential for developing treatments for conditions such as glaucoma, which is characterized by elevated intraocular pressure and can lead to vision loss if left untreated. Additionally, studying the ciliary epithelium can provide insights into the pathophysiology of other eye diseases and help improve our understanding of ocular physiology.
