What is uveoscleral outflow?

Uveoscleral outflow refers to one of the pathways through which aqueous humor, the fluid inside the eye, drains. Specifically, it involves the movement of this fluid from the anterior chamber of the eye through the uveal tissue and sclera, ultimately reaching the systemic circulation. This pathway plays a crucial role in regulating intraocular pressure and is a target for certain glaucoma treatments. Increased uveoscleral outflow can help reduce intraocular pressure and prevent damage to the optic nerve.
