The Eye Series: Retina

Book Appointment

Today we are learning about the retina. The retina is a 10 layered structure located at the back of the eye. Its main function is to receive incoming light rays and convert them into electrical signals that are sent to the brain. Specialized cells in the retina called ganglion cells have tails (axons) which come together to form the optic nerve. These axons function similarly to copper cables which  transport electrical signals over long distances. The electrical signals generated by the cells of the retina are carried through the ganglion axons and optic nerve and reach the visual cortex located at the back of the brain. At the visual cortex the signals are decoded and processed which allows us to see an image.

Age-related macular degeneration is a common retinal disease which occurs as we  grow older. Macular degeneration occurs when the retinal cells in the macula region are damaged and are unable to perform their regular functions. This region of the retina is very important for detailed central vision, so damage to the cells can cause a blind spot in the middle of your visual field.
