Retinal Disorders Information

What are Retinal Disorders

Retinal disorders which are also known as retinal conditions are a major reason for loss of vision in the United States. The retina is a fine lining at the back of the eye and it contains is made of cells that capture visual images and transfer them to the brain.

Retinal disorders include- diabetic retinopathy, age-related macular degeneration and retinal detachment.

Causes of Retinal Disorder

There are many causes of retinal disorder:-

Retinal Detachment - When the retina gets detached from the underlying tissue inside the eye, it is known as retinal detachment. Retinal detachments happen as a result of a tear, break or hole. The retinal tear may happen when the vitreous gel becomes loose or detaches from the retina. Retinal detachment can happen because of an injury or bleeding if there is a tear in the retinal blood vessel.

Diabetic Retinopathy - Diabetes can also lead to diabetic retinopathy. In this when there is too much sugar in the blood; it damages the small blood vessels that take care of the retina. This eventually results in diabetic retinopathy and vision loss. When the sugar level in the blood shoots up, it affects the blood vessels. These blood vessels swell which cause a blurred vision. Diabetic retinopathy is one of retinal disorders.

Age Related Macular Degeneration - Age-related macular degeneration is a disease related with aging which damages the usual vision and eventually the central vision. Central vision is very important to see objects that are at a distance as well as driving and reading.

Age related macular degeneration affects the macula. It is that part of the eye that helps in seeing minute details. The patient does not experience any pain in AMD. In few cases, age-related macular degeneration happens very slowly, therefore there is a gradual vision loss.

Retinal Disorder Symptoms

Retinal disorder does not involve any pain and in extreme cases retinal disorder can cause vision loss. Symptoms are given below:-

  • Minute specks, cobwebs, or spots, hair appear to float in the vision area. A sudden appearance or increase is a symptom of retinal detachment.
  • Difficult in seeing
  • Dark streaks or red film block the vision field.
  • Swelling in the eye
  • Unable to see clearly in the night
  • Pain in the eye
  • Blurred or loss of vision
  • Headache

Retinal Disorder Treatment

Retinal Disorder Laser Treatment

  • To treat the retinal disorder, argon laser is used.
  • This treatment involves sequential burns that are applied to the retina.
  • It also brings down the oxygen requirement for the central retina.
  • It reduces the abnormal growth of blood vessels that have chances of bleeding.
  • Macular edema can treat argon laser.

Retinal Disorder Vitrectomy

  • When the blood vessels start leaking in the vitreous, it results in vitreous hemorrhage.
  • Light bleeding gets reduced immediately but moderate or heavy needs vitrectomy.
  • Vitrectomy is done under local or general anesthesia.
  • The surgeon makes a small cut in the eye. Then a small instrument, vitreous gel is removed.
  • The surgeon may also suggest endo laser.
