A cell that lines the trabecular meshwork, which is an area of tissue in the eye located around the base of the cornea, near the ciliary body, and is responsible for draining the aqueous humor from the eye via the anterior chamber (the chamber on the front of the eye covered by the cornea). This cell may play a role in regulating intraocular pressure. [ GOC:tfm http://www.ncbi.nlm.nih.gov/pubmed/14500801 ]
