The retina is the inner most layer of the eye and is the imaging centre.
Located at the back where the optic nerve is, the retina is responsible for turning light into nerve signals from the back wall of the eye to the area of the brain responsible for sight.
Conditions that can affect your retina (e.g. ageing, chronic diseases like diabetes and trauma to the eye) may lead to vision loss.
THONEH’s Consultant Ophthalmologists are well experienced in treating various retinal conditions to prevent vision loss. They are experts in their field using the latest technologies and best practices for diagnosis and management of these conditions.
Diabetic retinopathy occurs when the blood vessels in the retina are damaged due to long-standing or uncontrolled diabetes.
Unfortunately there are no signs or symptoms in the early stages of diabetic retinopathy.
As the damage to the retina progresses, symptoms that may be experienced are:
Management of diabetes is crucial to prevent further loss of sight due to diabetic retinopathy.
Additionally, the following procedures can be carried out to repair the damage caused by the condition:
Intravitreal Anti-VEGF injections are given to patients …
If you have diabetes you should visit your ophthalmologist regularly to ensure that your retina is healthy.
In some cases, these flashes can appear on and off for a long period of time, and is more common as we grow older.
Retinal detachment is the separation of the retina from its attachment on the back wall of the eyeball. It can cause the retina to lose its function or be damaged, and can lead to partial or complete loss of vision.
Causes and risk factors for retinal detachment are:
The symptoms and signs of retinal detachment are:
If you have symptoms such as floaters and flashers, you should immediately visit your Ophthalmologist to ensure that your retina is still healthy and to prevent any vision loss.
Age-related Macular Degeneration (AMD) is a chronic eye disease and one of the leading causes of severe vision loss in people 60 years of age and above. It is also one of the leading causes of adult blindness in the world.
Contrary to what many believe, vision loss – and specifically AMD – does not have to be an inevitable consequence of ageing. Protect your vision by being active in your healthcare. Visit your eye doctor regularly.
AMD is a disease that can affect the sharp central vision needed for “straight-ahead” activities like reading, driving, telling time and recognize faces.
Sometimes AMD advances so slowly that you notice little change in vision. Sometimes AMD progresses quickly, resulting in rapid vision loss. AMD causes no pain, but can rob you of you ability to see what is on front of you. There are two types of AMD: Dry & Wet.
In dry AMD, which makes up to about 85% of all AMD cases, the light-sensitive cells in the retina die, affecting “straight-ahead” vision. The most common symptom of dry AMD is blurred vision. Dry AMD tend to develop slowly, but may develop into a more severe form of AMD called wet AMD.
Wet AMD, accounts for about 15% of all AMD cases, has abnormal blood vessels growing under the macula. This may lead to bleeding, scar formation and permanent damage. Damage occurs more rapidly than in the dry form and tends to lead to more severe loss of central or “straight-ahead” vision. If detected in time, relevant treatments may stop the progression of vision loss.
The two greatest risk factors for developing AMD are:
Other risk factors for developing AMD include:
Symptoms of AMD include:
The Amsler Grid may be helpful in revealing signs of wet AMD. It is not a substitution for a regular eye test.
Direction of use:-
Some people ignore symptoms of vision loss because they consider them to be a normal part of ageing process. Regular screening examinations can detect early signs of AMD.
Regular visit to the eye doctor will help in detecting not only AMD but other eye diseases. Early diagnosis and treatment may help preserve the sight you still have.
AMD causes permanent vision loss. Successful treatment can stabilize and /or slow vision loss or in some cases, restore vision. Although new treatments are always being researched, treatment options today are:
