The left side of the exhibit displays a right sagittal view of a normal eye. A graphic box is shown around the anterior chamber and lens. The upper right side of the exhibit displays an enlargement of the highlighted area, including the cornea, anterior chamber, iris, lens, ciliary body, Schlemm’s canal, and vitreous. Graphic arrows demonstrate the normal drainage flow from ciliary bodies, under iris, into anterior chamber, and exiting through uveoscleral drainage. The lower right side of the exhibit displays the same enlarged anatomy with the exception that the anterior chamber is shown as shallow. The drainage pathways are displayed as blocked by the iris with graphic arrows demonstrating drainage back into the posterior chamber.
