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 about your optic nerve to your brain so you can see.
Some diseases of the retina can be treated. Depending on your condition, the goal of treatment may be to stop or delay the disease and maintain, improve or restore your vision. If left untreated, some diseases of the retina can cause severe vision loss or blindness.
Symptom
Many diseases of the retina have some common signs and symptoms. These might be:
- See floating spots or cobwebs.
- Blurred or distorted vision (straight lines are wavy)
- Error in pageview
- Lost vision
- You may have to try to look only with each eye to notice them.
It is important to be alert to changes in your vision and find help quickly. Consult a doctor immediately if you have swimmers, flashes or blurred vision. These are warning signs of potentially serious retinal diseases.
Types
Common diseases and conditions of the retina are:
Retinal Tear. A tear of the retina occurs when the transparent substance, similar to a gel, in the centre of your eye (vitreous) contracts and pulls the thin layer of tissue covering the fundus (retina) with sufficient tensile force to make that the tissue breaks. It is often accompanied by the sudden onset of symptoms such as swimmers and blinking lights.
The detachment of the retina. Retinal detachment is defined by the presence of fluid under the retina. This usually occurs when the fluid flows through a retinal tear and lifts the retina from underlying layers of tissue.
Diabetic retinopathy. If you have diabetes, the small blood vessels (capillaries) in the back of the eye may get worse and the fluid may enter and enter the retina. As a result, the retina becomes inflamed, which can lead to vision problems. Or develop new and abnormal capillaries that break and bleed. This also makes your sight worse.
Epiretinal membrane. The epiretinal membrane is a delicate scar or tissue-like membrane that looks like wrinkled cellophane in the retina. This membrane is raised in the retina, which affects your vision. Objects may appear blurred or distorted.
Macular hole. A macular hole is a small defect in the centre of the retina in the fundus (macula). The orifice may develop due to abnormal traction between the retina and the vitreous, or after an injury to the eye.
Macular degeneration In macular degeneration, the centre of the retina begins to deteriorate. This leads to symptoms such as blurred central vision or a blind spot in the centre of the visual field. There are two types: wet macular degeneration and dry macular degeneration. Many people first have the dry form, which can go to the wet form with one or both eyes.
Retinitis pigmentosa. Retinitis pigmentosa is a degenerative disease that affects the retina.
Mudra for Degeneration of the retina
Retinal degeneration is the deterioration of the retina caused by the progressive and eventual death of the cells of the retina.

The practice of Gyan mudra or Vayu-vardhak mudra is useful to overcome degeneration of the retina.
