Retinal Detachment

What is Retinal Detachment?

The retina is the light sensitive layer of the eye one which light entering the eye via the pupil is focused. The information gathered by the retina is then sent to the brain via the optic nerve and is interpreted into an image. In retina detachment, the retina becomes disconnected from the other layers of the eye. It is a serious eye condition as it threatens one's sight.

Causes

As the vitreous (clear, jelly-like substance that fills the eye) tugs ro moves against the retina, it can pull or tear the retina. When a retina tear is present, fluid can enter the hole and push the retina off (retinal detachment). People who fall within the following categories are at higher risk of being affected:

  • Have very high myopia
  • Previous eye trauma
  • Family history of retinal detachment
  • Previous cataract surgeries
  • Retinal detachment has occurred in the other eye
  • Aged 40 and above

In addition, the condition seems to be more common in men than in women.

Symptoms

People suffering from retinal detachment experience loss of vision in the form of shadows or curtains over their sight. They also experience flashes and floaters. Flashes are occasional flashes of light that are caused by the vitreous (clear, jelly-like substance that fills the eye) tugging or moving against the retina. Floaters, on the other hand, are small, mosquito-like shapes that appear to float in the field of vision. However, small detachments may bring about no symptoms.

Treatment

Surgery is normally required once retinal detachment occurs as laser treatment to patch up the tear is no longer effective. The type of surgery varies with the type of retinal detachment. One type is the injection of a gas bubble into the eye to reattach the retina.
