ABO eye anatomy exam questions and
answers2
Cornea - ANSWERS-The clear front window to the eye. It is the most important part of the
focusing system of the eye and brings objects into focus on the retina.
Anterior Chamber - ANSWERS-The space between the cornea and the iris which is filled with
fluid aqueous.
Chamber Angle - ANSWERS-The structure formed by the junction of the iris with the corneo-
sclera. Normal fluid drainage from the eye occurs through the trabecular meshwork which lies
in the chamber angle. Malfunction of the chamber angle is the cause of glaucoma (high
pressure in the eye).
Iris - ANSWERS-The colored tissue behind the cornea - color varies from pale blue to dark
brown.
Pupil - ANSWERS-The round hole in the iris. Its size is automatically varied to regulate the
amount of light entering the eye.
Lens - ANSWERS-A clear biconvex structure behind the iris which works in conjunction with the
cornea to focus light onto the retina. When the lens becomes opaque or cloudy, it is called a
cataract.
Ciliary Body - ANSWERS-A ring of tissue lying at the base of the iris. Its muscle fibers serve to
change the curvature of the lens and thereby provide fine focusing of light onto the retina.
Zonules - ANSWERS-Threadlike filamentous attachments which hold the lens in place in the eye.
