Welcome to the retina center on our website. We treat and diagnose a wide variety of retina eye issues. Our Denver retina eye doctors invite you to contact us if you have retina eye issues such as diabetic retinopathy, macular degeneration or are experiencing things such as flashes and floaters. Early detection of retina problems can save vision.
The retina is the back surface inside the eyeball, opposite the lens. It contains millions of light sensitive cells, called rods and cones. An image projected by the lens onto the retina is sensed by the rods and cones as different intensities of light and different colors. When light hits rods or cones, a biochemical reaction occurs, which initiates the transmission of signals along nerve cells to the brain, with information about light, color and position in the retina. In the brain, the signals from throughout the retina are assembled into the experience of seeing what is before us.
Other important definitions for understanding the retina:
The central portion of the retina directly opposite the lens, is called the macula. It is rich in cones, the cells, which enable us to see fine detail and color. There are three classes of cones, each most sensitive to a different color: red, green or blue.
At the center of the macula is very small area called the fovea. Cones are most concentrated in the fovea. Despite its small size, relative to the rest of the retina, the fovea is very important for our ability to see fine detail and color.
