What is Retinal Detachment?
Retinal detachment occurs when the retina, an important layer of tissue, peels away from the blood vessel that provides it with necessary oxygen and nutrients. This could be a result a retinal tear, and often occurs without a warning.
How does it Affect the Eye?
Retinal detachment is a phenomenon where a layer of the retina moves away from its original position. When this occurs, it leaves the cells of your retina lacking nourishment and oxygen. At first, retinal detachment leads to just blurry vision. However, if it is left without any treatment, it is certainly possible to completely lose your vision at some point.
How Many Types of Retinal Detachment are there?
There are three types of retinal detachment:
Exudative Retinal Detachment:
In this form retinal detachment, the retina does not peel away from its place. Instead, fluid leaks into the spot that is under the retina, a result of certain inflammatory eye disorders or any injuries to the eye/eyes.
Rhegmatogenous Retinal Detachment:
This is the most common form of retinal detachment. When a retinal tear occurs, fluid leaks under the retina and disconnects it from the retinal pigment epithelium.
Tractional Retinal Detachment:
This is a less common form of retinal detachment where any scars on the retina contract to separate the retina from the retinal pigment epithelium.
What are the Symptoms of this Condition?
The symptoms of retinal detachment are:
- Your peripheral vision darkens
- You can see flashes of light
- You can see tiny thread-like substances of flecks in your vision
What are the Risk Factors for Developing this Condition?
Some of the risk factors include:
- If you are highly nearsighted, retinal detachment can happen to you
- If this has already occurred in one of your eyes, it could happen to your other eye as well
- If you have had eye injuries or diseases before, or even an eye surgery such as a cataract removal, your chances of facing retinal detachment are high
- You can expect to face this condition if your family has a history of it
How is this Condition Treated?
There are two procedures that could be done at the doctor’s office: cryopexy (a form of freeze treatment) and laser surgery. While cryopexy freezes the spot that has the retinal tear, laser surgery welds the area shut by causing small burns there.
Today, almost 90% of the cases of retinal detachment can be treated successfully. However, many of these cases require a second treatment. Unfortunately, you cannot receive instant results after the treatment; results can be seen only after some months of the treatment.
