Study Notes
Structure and Function of the Eyeball
- The anterior segment of the eyeball is responsible for refracting light and regulating the amount of light that enters the eye.
- The anterior 1/6 of the outer layer of the eye is made up of the cornea, a transparent layer.
- The posterior segment of the eyeball is primarily responsible for converting light into electrical signals that are transmitted to the brain.
- The fibrous and vascular layers of the eye are located in the outer coat, which is divided into three main parts: sclera, choroid, and retina.
- The neural outer coat, also known as the retina, is located in the posterior segment of the eyeball and contains specialized light-sensitive cells called photoreceptors.
