WHAT IS A RETINA ?
The eye works like a camera. The lens system in the front of the eye (cornea, pupil and lens) focuses light onto the back of the eye, the retina. The retina is the inner lining of the eye and works like the film in a camera; it senses light and allows you to see by transmitting this information to your brain where it is interpreted as images. Light hits the retina after passing through a space in the center of the eye called the vitreous cavity. This cavity is filled with a clear, jelly-like substance called vitreous. The macula is the central area of the retina and is the only area that can see fine details.
Damage to the macula can serverly affect your central vision Vitreous and make it difficult to perform activities such as reading fine print, recognizing faces, and threading a needle.
