The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain. When the retina detaches, it is lifted or pulled from its normal position. If not promptly treated, retinal detachment can cause permanent vision loss.

1. The retina is the light-sensitive layer of tissue that lines the
inside of the eye and sends visual messages through the optic
nerve to the brain. When the retina detaches, it is lifted or pulled
from its normal position.

2. In some cases there may be small areas of the retina that are torn.
These areas, called retinal tears or retinal breaks, can lead to
retinal detachment.

3. Types and Causes of Retinal Detachment
There are three types of retinal detachment:
• Rhegmatogenous
• Tractional
• Exudative

4. •1 RHEGMATOGENOUS RETINAL DETACHMENT
If you have a Rhegmatogenous retinal detachment, you have a
tear or hole in your retina. This allows fluid from within the eye
to slip through the opening and get behind the retina.

5. •2 TRACTIONAL RETINAL DETACHMENT
Tractional retinal detachment occurs when scar tissue on the retina’s
surface contracts and causes the retina to pull away from the back of
the eye. This is a less common type of detachment that typically
affects people with diabetes.

6. •3 EXUDATIVE DETACHMENT
In Exudative detachment, there are no tears or breaks in the retina. This
type of detachment is caused by retinal diseases such as inflammatory
disorder or Coats disease, which causes abnormal development in the
blood vessels behind the retina.
