The anterior chamber in front of the lens and iris is filled by aqueous humor produced by the ciliary body . The aqueous humor, in a nutrient role, circulates and drains out to exiting via the canal of Schlemm . If this drainage is blocked, pressure builds up and glaucoma results. The visual pathway is long and involved. Briefly, relected light must pass through the cornea, aqueous humor, lens, vitreous humor, and be focused on retina.
