18 Mar Retina, Macula and Vitreous
The retina is the light-sensitive tissue lining the back of our eye. Light rays are focused onto the retina through our cornea, pupil and lens. The retina converts the light rays into impulses that travel through the optic nerve to our brain, where they are interpreted as the images we see. A healthy, intact retina is key to clear vision.
The central part of the retina is called the Macula. It is the most important part and is responsible for the central vision and fine vision.
The middle of our eye is filled with a clear gel called vitreous that is attached to the retina. Sometimes tiny clumps of gel or cells inside the vitreous cast shadows on the retina, and may be sometimes seen as small dots, specks, strings or clouds moving in the field of vision.
