The trabecular meshwork is important because it is the area where the aqueous humor drains out of the eye. Cornea: clear front window of the eye that transmits and focuses light into the eye. The retina acts like an electronic image sensor of a digital camera, converting optical images into electronic signals. When focused light strikes the retina, chemical reactions occur within specialized layers of cells. Glossary of Terms. Anterior chamber: The region of the eye between the cornea and the lens that contains aqueous humor. The inside lining of the eye is covered by special light-sensing cells that are collectively called the retina. 95.
