Retinal Conditions
Understanding the Retina
The retina is a specialized light- sensing tissue lining the back of our eyes. The retina’s light- sensing cells are divided into two types, rods and cones. Rods are sensitive to light/ dark amounts of light as well as movement, and cones detect color and fine detail.
Light rays are focused onto the retina through the cornea, pupil and lens. The retina then converts these light rays into impulses that travel to our brain, where they are interpreted as the images we see. The retina functions as the film inside a non- digital camera,though the retina is far more complex.A healthy, intact retina is needed for clear vision.
Due to the important role that the retina plays in sight, retinal damage and disease can cause serious vision problems and even blindness. As with many areas of health, preventing problems from occurring is easier and often more successful than solving these issues after they develop.
