This is the fluid-filled space in the front part of the eye, located immediately behind the cornea but in front of the iris. This “chamber” is filled with clear aqueous fluid and easy to examine by the doctor using the slit lamp microscope in the office. In cases of trauma or iritis, the anterior chamber may be filled with inflammatory cells that can be detected in the office. In more severe cases of trauma, blood can fill this space … this is called a hyphema. If you have acute glaucoma, the anterior chamber can be shallow as the aqueous fluid cannot drain out properly.
