Retina and its different diseases

Image

The retina is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs. The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception. The retina serves a function which is in many ways analogous to that of the film or image sensor in a camera.

Retinal diseases vary widely, but most of them cause visual symptoms. Retinal diseases can affect any part of your retina, a thin layer of tissue on the inside back wall of your eye.

The retina contains millions of light-sensitive cells (rods and cones) and other nerve cells that receive and organize visual information. Your retina sends this information to your brain through your optic nerve, enabling you to see.

Treatment is available for some retinal diseases. Depending on your condition, treatment goals may be to stop or slow the disease and preserve, improve or restore your vision. Untreated, some retinal diseases can cause severe vision loss or blindness.

Common retinal diseases and conditions include:

  • Retinal tear: A retinal tear occurs when the clear, gel-like substance in the center of your eye (vitreous) shrinks and tugs on the thin layer of tissue lining the back of your eye (retina) with enough traction to cause a break in the tissue.
  • Retinal detachment. A retinal detachment is defined by the presence of fluid under the retina.
  • Diabetic retinopathy. If you have diabetes, the tiny blood vessels (capillaries) in the back of your eye can deteriorate and leak fluid into and under the retina.
  • Epiretinal membrane. Epiretinal membrane is a delicate tissue-like scar or membrane that looks like crinkled cellophane lying on top of the retina.
  • Macular hole. A macular hole is a small defect in the center of the retina at the back of your eye (macula).
  • Macular degeneration. In macular degeneration, the center of your retina begins to deteriorate.
  • Retinitis pigmentosa. Retinitis pigmentosa is an inherited degenerative disease. It slowly affects the retina and causes loss of night and side vision.
