Optic Nerve

The cranial nerves that relay messages from your eyes to your brain to create visual images. These nerves extend from the retina in the back of the eyes to the part of the brain that processes what we see. In myelinAn insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells. If myelin is damaged, these impulses slow down. oligodendrocyte glycoproten antibodyA protective protein produced by your immune system that attaches to antigens (foreign substances), such as bacteria and toxins, and removes them from your body. In myelin oligodendrocyte glycoproten antibody disease (MOGAD), the body incorrectly produces an antibody that targets myelin oligodendrocyte glycoprotein, a component of the myelin sheath in the central nervous system. disease (MOGADOften referred to as MOGAD, Anti-MOG, MOG Ab+, MOG Antibody Disease, MOG Associated Antibody Disease, MOG positive disease  ), they may be the target of inflammationA process of the immune system that involves chemicals released by immune cells (i.e. white blood cells) inducing localized heat, swelling, redness, and pain to an area that occurs when tissue becomes damaged or infected from a pathogen, and usually results in the desctruction and removal of the pathogen and/or healing to the tissue. In the case of myelin oligodendrocyte glycoprotein antibody disease (MOGAD), inflammation is the result of the incorrect targeting of the myelin oligodendrocyte glycoprotein (MOG) by the immune system, resulting in damage to myelin sheaths. or lesions, sometimes causing visual disruption or blindnessAny alterations in your ability to see normally which may include blurred vision, cloudy vision, double vision, color change, seeing spots in your vision, or loss of vision. Vision changes may occur in one or both eyes. With MOGAD, vision changes are caused by optic neuritis..
