Retina is the receiving component of the eye which is on the back side of lens. Retina is rich in blood supply
Diseases effecting Retina vary widely, and most of them cause visual disorders
Retina is made of nerve cells which receive visual information and are called rods and cones; the same information is passed to the brain through optic nerve enabling vision.
For most of the retinal disorders, treatments are available to either restrict the vision loss or to restore the vision. If retinal disorders are untreated, the condition may lead to blindness.
- Sudden loss of vision.
- Defects in the visual fields.
- Blurred or distorted vision.
- Seeing Floaters/cobwebs.
- Some corneal conditions can be very painful.
Risk factors for retinal diseases might include aging, having diabetes or other diseases, eye trauma, and a family history of retinal diseases
When to see a Doctor
A periodic Retinal check up is essential if suffering with Diabetes and Hypertension or if having a family history. Apart from this, whenever there is a sudden change in vision it’s the time to seek immediate help from Eye Doctor.
Common retinal diseases and conditions include
- Retinal Tears: A Retinal tear occurs when clear gel like substance in the eye (Vitrous) shrinks due to any reason. Symptoms will be sudden and most common symptoms are Floaters and Flashing lights. Immediate visit to the Dr is recommended
- Retinal Detachment: A retinal detachment is a condition by the presence of fluid under the retina. This usually occurs when fluid passes through a retinal tear, causing the retina to lift away from the underlying tissue layers.
- Diabetic Retinopathy: Diabetes effects retina in the form of growing additional blood vessels called as Proliferative Diabetic Retinopathy and also leakage of blood into back side of the retina causing swelling in the retina. Burred and distorted visions are the key symptoms.
- Epiretinal Membrane: A tissue like scar is formed on the surface of Retina resulting in diminished and dull vision.
- Macular Hole: A macular hole is a small defect in the center of the retina at the back of your eye (macula). The hole may develop from abnormal traction between the retina and the vitreous, or it may follow an injury to the eye.
- Macular Degeneration: In macular degeneration, the center of retina begins to deteriorate. This causes symptoms like a blind spot in the center of the visual field or blurred central vision. There are two types — wet macular degeneration and dry macular degeneration. Many people will first have the dry form, which can progress to the wet form in one or both eyes.
- Retinitis Pigmentosa:. Retinitis pigmentosa is a degenerative disease that affects the retinal nerve cells resulting in gradual diminishing vision.
