They say the eyes are the window to the soul, but they’re also highly specialized organs that offer us our window on the world. We’re a sight-based species, but sometimes the delicate, complex structures of the eye can develop injuries or diseases that can threaten our vital sense of sight.
The eyeball contains many critical parts, including:
The pupil: the black opening in the middle of the eye that lets light into the eye.
The iris: the colored part of the eye that helps regulate how big the pupil is and thus how much light enters the eye.
The cornea: the outer sheath that covers the pupil and iris and helps focus light onto the retina at the back of the eyeball.
The lens: a sheath of tissue that sits behind the iris and further focuses light and visual information onto the retina.
The sclera: the white of the eye.
The conjunctiva: a thin film that covers the white part of the eye and encases the back of the eye.
The retina: a thin film at the back of the eye that organizes visual information and transmits it to the optic nerve.
The macula: a point in the center of the retina.
The optic nerve: a nerve that runs from the back of the eye to the brain and transmits visual information to be interpreted by the brain.
There are other components inside the eye as well, including blood vessels, fluid and other structures that help keep the eyeball functioning the way it should. Any one of these components can become diseased or injured, and some of the most common types of eye diseases that can arise are outlined below.
