Optic Hole

The optic foramen is a small opening in the skull that is located on the back wall of the eye socket. It is responsible for communication between the eye and the brain. The optic nerve passes through this hole, which transmits signals from the eye to the brain. If the optic hole becomes closed or damaged, it can lead to blurred vision and other problems with the visual system.

The optic hole has the shape of a circle. The size of the optic aperture varies from person to person, but it usually ranges from 2.5 to 4 millimeters. Inside the optic opening are the lens and vitreous humor, which help focus light on the retina.
