Retina Check-UP

Retina is the neurosensory layer of the eye which is present inside and at the back of the eye. It is on this layer that an image seen by the eye is formed, which is converted to nerve signals and transferred to the brain. Hence person with a normal eye but with a retina disease will have poor vision. The Retina is the light sensitive film in the back of the eye. The image is perceived here and transmitted to the brain by the optic nerve. The vitreous is the clear gel that fills the back of the eye. Diseases of the retina can affect any age.

The common disease affecting the retina is:-

Diabetic eye disease

What is diabetic eye disease?
It is that type of eye problems that people with diabetes may get. All of these eye problems can lead to vision loss or blindness.
Here are some of these eye problems:

  • Diabetic retinopathy—It generally cause harm to the blood vessels in the retina. The retina is the layer of tissue in the back of the eye that is sensitive to light.
  • Cataract— It leads to cause your eye lens to get cloudy.
  • Glaucoma— It leads to cause damage to the optic nerve that can lead to vision loss.

Who is most likely to get diabetic eye disease?
This is most commonly found in anyone having diabetes. The longer someone has diabetes, the more likely they are to get diabetic eye disease.

Which diabetic eye disease do most people get?
Diabetic retinopathy is a leading cause of blindness in people with diabetes. This disease happens when blood vessels in the retina get weak and leak fluid. It also happens when new blood vessels grow on the surface of the retina. As the new blood vessels grow on the surface of the retina, they can bleed into the eye and block vision.

What are the symptoms of diabetic retinopathy?
It is often seen that at the early stages of the disease, many times there are no symptoms or pain. As some blood vessels get weak and leak fluid or bleed, vision may start to blur.

How can it be prevented?
People with diabetes can dramatically slow or prevent the development of this eye disease by keeping their blood sugar, blood pressure, and blood cholesterol under control and having regular eye exams to check on the eye disease.

How is diabetic retinopathy treated?
Laser eye surgery can close or shrink the new abnormal blood vessels that can leak blood into the eye and cause vision loss. It can also slow or stop the fluid leakage from retina vessels that can cause vision loss. The latest treatment includes injections of drugs into the eye to prevent this leakage and this often leads to improved vision.
