Retina

  • Definition
    • The retina is the light-sensitive layer of tissue at the back of the eyeball. Images that come through the eye's lens are focused on the retina. The retina then converts these images to electric signals and sends them along the optic nerve to the brain.

      The retina usually looks red or orange because there are many blood vessels right behind it. An ophthalmoscope allows a health care provider to see through your pupil and lens to the retina. Sometimes photos or special scans of the retina can show things that the provider cannot see just by looking at the retina through the ophthalmoscope. If other eye problems block the provider's view of the retina, ultrasound can be used.

      Anyone who experiences these vision problems should get a retinal examination:

      • Changes in sharpness of vision
      • Loss of color perception
      • Flashes of light or floaters
      • Distorted vision (straight lines look wavy)
