A detached retina is a condition which affects the eyes. In this situation, the retina gets pulled away from its original position at the center of the eye. If you don’t have this condition treated right away, it may lead to permanent blindness. No matter how small the region of the retina gets pulled away, it will result in a detached retina.
Detached retina has a lot of symptoms. One of the primary symptoms is when spots (or floaters) start spreading on the surface of the retina. When these spread, they will start affecting the person’s field of vision. How fast the condition progress differs from person to person. Sometimes a person might even see flashes of light or dark regions in the corner of their vision. To understand detached retina better, let’s answer some of the frequently asked questions.
1. What are the different types of a detached retina?
There are three major types of a detached retina. They vary according to the severity, cause, and commonality. Rhegmatogenous detached retina refers to a break or tears in the retina. This would allow fluid to penetrate under the retina, thus separating it from the RPE or retinal pigment epithelium. This is the most common type of detached retina.
Tractional detached retina refers to scar tissue forming on the surface of the retina. Because of this, it starts to contract then separate from the RPE. This type is less common than the first one. Finally, exudative detached retina usually occurs because of retinal diseases, trauma or injury. Here, fluid leaks underneath the retina even though there aren’t any breaks or tears.
