What is it? Retinal detachment is classed as a medical emergency, which if left untreated may lead to loss of vision in the affected eye.
How does it happen? When the sensory retina separates from the retina pigment epithelium it is what’s known as retinal detachment.
What are the causes? Most retinal detachments occur when a tear or hole in the retina leaks fluid into the retinal layers. This then causes the detachment. These tears can simply be caused when we get older, blows to the head or if the vitreous gel is suddenly detached from the retina (posterior vitreous detachment, PVD)
Who is at risk? There is an increased risk if you are very short sighted (more than minus 6.00D). If you have suffered a blow to the head or some kind of head trauma to the eye. Or if you have a family history of retinal detachment.
Are there any symptoms? Some may experience flashing lights, more commonly around the edge of your vision. Floaters can be caused by debris in the viteous causing shadows on the retina. These are very common and we can expect to see a few as we get older. Dark shadows may be apparent in the corner of your vision. If more of the retina detaches the shadow moves to the centre of your vision.
How do I prevent it? There is no treatment that can reduce your risk of this but regular eye tests are an important way to make sure your eyes do remain healthy. Always make sure you wear eye protection if you are doing DIY, gardening or sports. Remember, retinal detachment does not happen if you are lifting heavy things or straining.
Can I get treatment? It is treatable, it does involve an operation to reattach the sensory retina. The surgery can be complicated but is individual to every single person. Only one operation is needed and can be performed under a local anaesthetic.
