Rentinal Detachment

Retinal Detachment is the condition where the retina of the eye detaches or tears itself from its normal position. In this condition, retina tears away from the blood vessels that supply it with blood.

Retina is the light sensitive layer of tissue that is critical to formation of image. Retina receives the light from the cornea of the eye and conveys the image to the brain through optic nerve. Because of its critical function, retina is connected with several blood vessels that maintain a continuous supply of oxygen rich blood to the cells of the retina.

Retinal Detachment is considered a medical emergency because the risk of cell damage because of lack of blood. The longer the cells of the retina are without fresh blood, the greater is the risk of permanent damage to retina and consequently vision loss.

Retinal Detachment is common in people above the age of 40. however, younger people who suffer from disorders of retina are also susceptible to the issue. There are several warning signs that should prompt these patients to seek immediate medical attention.

Types Of Retinal Detachment

The episodes of Retinal Detachment could be divided into three distinct categories:
  • Rhegmatogenous: These are the most common type of Retinal Detachment. In this condition, fluids leak underneath the retina and cause it to separate from retinal pigment epithelium.
  • Tractional: In this condition, the scar tissues on the retina contract and separate it from retinal pigment epithelium.
  • Exudative: in this condition, fluids leak under the retina but there is no major tear.
