Retina

The retina (from Latin: rete) 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 translates that image into electrical neural impulses to the brain to create visual perception.

The retina is the receiving component of the eye which is on the backside of the lens. The retina is rich in blood supply. Diseases affecting Retina vary widely, and most of them cause visual disorders. The retina is made of nerve cells that receive visual information and are called rods and cones; the same information is passed to the brain through the optic nerve enabling vision. For most retinal disorders, treatments are available to either restrict vision loss or restore the vision. If retinal disorders are untreated, the condition may lead to blindness.

HOW DO I KNOW IF I HAVE CATARACTS?

Symptoms

  • 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

Risk factors for retinal diseases might include aging, having diabetes or other diseases, eye trauma, and a family history of retinal diseases.

COMMON RETINAL DISEASES & CONDITIONS INCLUDE

Retinal Disorders

Retinal Disorders

A Retinal tear occurs when the clear gel-like substance in the eye (Vitreous) shrinks due to any reason. Symptoms will be sudden and the most common symptoms are Floaters and Flashing lights. Immediate visit to the doctor 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 the 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.
