eye scan Multiple Sclerosis by demi tay

A simple eye test may offer a fast and easy way to monitor patients with multiple sclerosis (MS) Optical Coherence Tomography (OCT) is a scan that measures the thickness of the lining at the back of the eye - the retina. It takes a few minutes per eye and can be performed in a doctor's surgery. The latest study tracked the patients' disease progression over a two-year period. Multiple sclerosis is an illness that affects the nerves in the brain and spinal cord causing problems with muscle movement, balance and vision. In MS, the protective sheath or layer around nerves, called myelin, comes under attack, which, in turn, leaves the nerves open to damage.
Usually after a decade or so, half of patients with this type of MS will develop secondary progressive disease where the symptoms get gradually worse and there are no or very few periods of remission. Another type of MS is primary progressive disease where symptoms get worse from the outset. There is no cure but treatments can help slow disease progression.
It can be difficult for doctors to monitor MS because it has a varied course and can be unpredictable. Experts suspect that this means the nerves here will show the earliest signs of MS damage. The study at Johns Hopkins found that people with MS relapses had much faster thinning of their retina than people with MS who had no relapses. So too did those whose level of disability worsened. Similarly, people with MS who had inflammatory lesions that were visible on brain scans also had faster retinal thinning than those without visible brain lesions.
Opinion: I think that having the scanning of eyes can check if the people have a faster retinal and will let the people know their chances of having problems with muscle movements, balance and vision. This check up with the brain scan can allow the doctor and the person to be more sure of them getting the disease or not so they will be more prepare and doctors can start to monitor them so to make sure they do not get the disease instead of knowing they have got disease when it had reached an incurable stage then they will be more heartbroken. But if they are prepare and have told his family and friends about themselves maybe getting the disease the family and friends by then will encourage them and thus they will not enter a depression stage when they got the disease. With them knowing the risk of getting the disease they will treasure their time have their families and friends and will be more careful with their diet.
