WHAT IS A RETINAL DETACHMENT? Sudden onset of visual loss in retinal detachment
Retinal detachment describes an emergency situation in which a thin layer of tissue (the retina) at the back of the eye pulls away from its normal position. Retinal detachment separates the retinal cells from the layer of blood vessels that provides nutrition. The longer retinal detachment goes untreated, the greater your risk of permanent vision loss in the affected eye. Retina becomes stiff and irreparable it becomes stiff this condition is called PVR.
Proliferative vitreoretinopathy (PVR) is a disease that develops as a complication of rhegmatogenous retinal detachment. PVR occurs in about 8–10% of patients undergoing primary retinal detachment surgery and prevents the successful surgical repair of rhegmatogenous retinal detachment.
What are the signs of a retinal detachment?
Warning signs of retinal detachment may include one or all of the following:
- The sudden appearance of floaters and flashes
- Reduced vision
- Visual filed loss
- Curtain drop obscuring your vision
Contacting an eye specialist (ophthalmologist) right away can help save your vision.
What are causes of retinal detachment?
There are three main causes of retinal detachment:
- Shortsightedness (myopia)
- Previous eye injury
- Advanced age
- Family history
- Detachment in the fellow eye
But the most common causes are aging or previous eye injury (including intraocular surgical procedures).
How is a retinal detachment treated?
Rhegmatogenous and tractional detachment will need surgical repair whereas in exudative detachment we treat the cause which is usually intravenous injections.
Are there different types of retinal detachment?
Yes. There are different types types of retinal detachment:
- Rhematogenous (caused by a retinal tear or break)
- Tractional (caused by forces pulling retina from the back of the eye)
- Combined tractionnal and rehegmatogenous
- Exudative (inflammatory)
Each type happens because of a different problem that causes your retina to move away from the back of your eye and thus causing visual loss.
What if you don’t want to have surgery ?
It depends on the type of detachment you have and your doctor will discuss different treatment modalities available to you. Most types of retinal detachment need surgical repair.
