The retina is a circular disc that measures approximately 30 to 40 mm in diameter. It is about 0.5 mm thick and lines the back of the eye.
In more detail:
-
Diameter: The total area of the retina occupies a circular space with a diameter ranging from 30 to 40 millimeters.
-
Thickness: The retina is a thin layer of tissue, only about 0.5 millimeters thick.
-
Location: The retina lines the inner surface of the posterior (back) part of the eye.
Therefore, understanding the size of the retina involves considering both its overall diameter and its thickness within the eye.
