Optic neuritis after COVID vaccination

A literature review on optic neuritis following vaccination against virus infections Optic neuritis (ON) is a primary inflammation of the optic nerve. ON is mostly idiopathic, and infrequently occurs on the background of systemic autoimmune disease, recent infectious disease or inoculation with mostly adjuvanted vaccines COVID-19 vaccination is recommended for multiple sclerosis patients. Disease-modifying therapies can influence the safety and efficacy of COVID-19 vaccines. RNA, DNA, protein, and inactivated vaccines are likely safe for multiple sclerosis patients. optic neuritis, and transverse myelitis (Kumar et al., 2020). However,. A 44-year-old male patient with no past medical history presented 2 weeks after seropositive coronavirus disease 2019 (COVID-19) infection with vision problems suggestive of optic neuritis. Radiological testing showed findings suspicious for acute bilateral optic neuritis. The patient had also anti-MOG antibodies

This case report details a patient who was diagnosed with myelin oligodendrocyte glycoprotein (MOG) antibody-associated optic neuritis and myelitis and COVID-19. Study findings The patient was a 26-year-old Hispanic man who presented with bilateral atypical optic neuritis and subsequently diagnosed with MOG-associated disease COVID-19 vaccine reports will be processed (i.e., reviewed, coded, - Optic neuritis (ON) - Chronic inflammatory demyelinating polyneuropathy (CIDP) - Encephaliti I received moderna vaccine 1st dose on Jan 15.

My physician said it was textbook vertigo and possible vestibular neuritis. After seeing specialist ( audiologist) diagnosed me with nystagmus in both eyes Some research has shown that optic neuritis is a rare complication from the vaccine for the measles-rubella (MR) vaccine. Optic neuritis is inflammation affecting the optic nerve that sends signals from the back of the eye to the brain. Common side effects of the MMR vaccine include COVID-19 vaccines (e.g., age of vaccinee, COVID-19 vaccine type, adverse event). Enhanced surveillance (i.e., automated data and clinical review) will be implemented after reports of the following adverse events of special interest (AESIs): death, COVID

  1. Attenuated live virus vaccination provides protection against rubella that is generally safe and effective. Infrequently, however, it is followed by neurologic complications, including paresthesia, 1,2 polyneuritis, 2 myeloradiculoneuritis, 3 and myelitis. 4-7 Kazarian and Gager 8 reported a case of bilateral optic neuritis following trivalent mumps, measles, and rubella vaccination
  2. We report about a young patient with a longstanding history of relapsing-remittent multiple sclerosis (RRMS) who developed a severe syndrome of optic/chiasm neuritis and paraplegia due to longitudinal extensive transverse myelitis (LETM) resembling NMOSD 2 weeks after her vaccination with the first dose of a vector-based COVID-19 vaccine
  3. The authors described a case of a 6-year-old girl who developed bilateral optic neuritis following inactivated influenza vaccination. Study design A previously healthy 6-year-old developed bilateral retrobulbar optic neuritis 1 week following inactivated influenza vaccination, which was supported by long segment enhancement of both optic nerves.
  4. The National MS Society has revised its COVID-19 vaccine recommendations first issued about a month ago. The guidelines still say the Moderna and Pfizer vaccines are considered safe for people.

It may be confused with the more common diagnoses of rotator cuff pathology, adhesive capsulitis (frozen shoulder), shoulder arthritis or cervical spondylosis

Background Several case reports of the onset or exacerbation of multiple sclerosis or other demyelinating conditions shortly after vaccination have suggested that vaccines may increase the risk of demyelinating diseases.. Objective To evaluate the association between vaccination and onset of multiple sclerosis or optic neuritis.. Design Case-control study involving cases of multiple sclerosis. A study by the National Immunization Program of the Centers for Disease Control and Prevention, published in the Archives of Neurology in 2003, found that vaccination against hepatitis B, influenza, tetanus, measles, or rubella did not increase a person's risk of developing MS or optic neuritis (which is often a first symptom of MS) The coronavirus 2019 (COVID-19) pandemic has potential to disproportionately and severely affect patients with neuromuscular disorders. In a short period of time, it has already caused reorganization of neuromuscular clinical care delivery and education, which will likely have lasting effects on the field. This article reviews (1) potential neuromuscular complications of COVID-19, (2. The move comes after the EMA found last month that COVID-19 vaccines from both AstraZeneca and Johnson & Johnson may have caused very rare blood clotting cases
