When the nerves can't function, neither can the organs & body parts they control. Inflammation of nerves can cause a wide range of symptoms, especially when the optic nerve is involved. And just as a lamp won't turn on with a broken cord, the nerves can fire without enough energy to activate them, resulting in ineffective function. The cracks in the plastic can allow the electricity in the cord to escape, just as the breakdown in the myelin can in the nerve shafts. Picture an old lamp cord with cracking plastic. Inflammation and hypoxia caused by COVID-19 can cause demyelination, or the breakdown of the myelin sheath. The purpose of the myelin sheath is to contain the current while the electrical impulses are on their journey, from end-to-end and or on to the next nerve. Nerves are contained in a myelin sheath, similar to a conduit or the plastic coating on a wire. ![]() ![]() The optic nerve in the brain is essential to communication from the eyes to the brain. Every thought, behavior, action and body function is the result of electrical signaling. Nerves are the pathways for electrical impulses to flow and initiate body functions. One of the risks of hypoxia is that it could lead to long term or permanent damage and demyelination of the nerve. Several factors in Long COVID can cause or contribute to low oxygen levels, so it can be challenging to identify a specific cause. ![]() Hyperferritinemia (high levels of stored iron)Ī common symptom of Long COVID is hypoxia (blood oxygen levels under 95%). Oxygen deprivation of the eyes or optic nerve Other issues that may contribute to vision changes or damage include: Doctors are still learning how COVID affects the eyes, but there is a concern about inflammation that can cause blood clots to form and travel through the body and reach the veins, arteries and blood vessels of the eye. While we continue to learn more about COVID and long COVID, researchers believe that COVID-19 causes the immune system to become overactive. To prevent infection this way, keep your hands clean when eating, avoid touching your face, and steer clear of people who are coughing or sneezing. You can catch COVID-19 when the viral particles (from things like spittle from sneezing or coughing) touch the membranes of your eyes or when you rub your eyes with dirty fingers that have touched something a person with the virus touched, including table tops and door handles.
