Monitoring Multiple Sclerosis with Eye Testing
About Multiple Sclerosis
Multiple sclerosis (MS) is a debilitating neurological disease that can cause patients to experience decreased vision due to optic neuritis, an inflammation of the optic nerve, as well as diplopia or double vision. We believe that MS occurs because there is an abnormal response of the body’s immune system whereby it is directed against the central nervous system (CNS), which is made up of the brain, spinal cord and optic nerves. Within the CNS, the immune system attacks myelin- the fatty substance that surrounds and insulates the nerve fibers as well as the nerve fibers themselves. When any part of the myelin sheath or nerve fiber is damaged or destroyed, nerve impulses traveling to and from the brain and spinal cord are distorted or interrupted, producing a wide variety of symptoms.
About Optical Coherence (OCT) Eye Testing for MS
In our office, we routinely use very precise imaging technology called Optical Coherence Tomography (OCT) as part of evaluation, diagnosis and monitoring glaucoma and retina diseases because it allows us to examine the actual nerve fibers of the retina and the optic nerve.
Recent research has taught us that OCT can be used to monitor the degree of atrophy of specific retinal layers-called the “inner plexiform layer” and “ganglion cell layer”-and used as an as an indicator of neuronal tissue damage in patients with multiple sclerosis (MS). For patients with Multiple Sclerosis this is quite valuable as it gives us a non invasive in office test, that in concert with their neurologists, helps us help patients asses the stability of their disease as well as their response to new medications or treatments.
