Retinal detachment is a condition when the thin lining at the back of the eye (the retina) begins to come away and separate itself from the underlying wall of the eye (the choroid) which contains blood vessels that supply it with vital oxygen and nutrients.
If not treated promptly, retinal detachment will lead to blindness in the affected eye.
A retinal detachment is usually caused by a tear in the retina and this is termed a Rhegmatogenous retinal detachment. There are other types of retinal detachment namely Traction retinal detachment which is usually seen in advanced diabetic retinopathy and Exudative retinal detachment (usually seen in people with inflammation). It is the Rhegmatogenous retinal detachment which needs urgent surgery in most cases.
Most people experience advance symptoms of a possible retinal detachment before losing their sight, including:
Without immediate treatment, the vision in the affected eye will start to deteriorate, creating the effect of a shadow or ‘black curtain’ spreading across the vision. If a person experiences a shadow in the vision then It is extremely important to consult an eye doctor immediately before the shadow spreads across the centre of the vision.
Retinal detachment usually only occurs in one eye, however if one eye is affected, there is a 1 in 10 chance that the retina in your other eye will also detach.
You should contact your eye doctor immediately if you get any of these warning signs.
The retina at the back of the eye sends signals to the brain, enabling us to see. Without a blood supply, the retina’s nerve cells die leading to loss of sight.
Retinal detachment is usually the result of the retina becoming thinner and weaker with age. This causes a tear in the retina and once a tear develops the retina can pull away from the underlying blood vessel wall (the choroid).
Very short-sighted people have the greatest risk of developing age-related retinal detachment (though the risk is still very small) because they are often born with a thinner than normal retina in the first place.
Previous eye surgery, such as cataract removal, may also make the retina more vulnerable to damage.
In some cases, a tear can develop if the eye is suddenly injured, such as by a blow to the face but this is less common.
If the eye specialist (ophthalmologist) suspects a retinal detachment, an examination of the back of the eye will confirm it.
Urgent Retinal Detachment treatment is essential to lower the risk of permanent vision loss. The Retinal Detachment treatment is mainly surgery and eye drops will not help.
Most but not all detached retinas can be successfully reattached through different types of surgery, followed by a few months of recovery when vision will be weak, affecting lifestyle activities such as driving.
Some people’s eyesight does not fully return after surgery and they have permanently reduced peripheral (side) or central vision. This can happen even if the retina is reattached successfully.
This risk is higher the longer the detachment was left untreated.
Retinal detachment is rare. For example, only one in every 10,000 people will develop it in any given year in the UK.
As retinal detachment is associated with ageing, most cases affect older adults aged between 60 and 70. Retinal detachment caused by an injury can affect people of any age, including children.
