A new study from Japan is raising major concerns among medical experts after a team of top Japanese researchers found a link between Covid mRNA shots and permanent blindness.

The study was led by Dr. Shin-ichiro Ohmura at Japan’s Seirei Hamamatsu General Hospital Department of Rheumatology.

The results from the study were published in Moderna Rheumatology Case Reports.

Dr. Ohmura’s team sought to better understand how Covid mRNA injections are associated with some patients to the development of systemic rheumatic diseases.

The study noted that cases of rheumatoid arthritis, myocarditis, Guillain-Barre syndrome, and giant cell arteritis (GCA) have been surging in people after receiving Covid shots.

In this case series, the Japanese authors report on a case of GCA with ischemic optic neuropathy after receipt of COVID-19 mRNA vaccination.

Ischemic optic neuropathy (ION) is a rare condition that causes vision loss or changes due to a lack of blood flow to the optic nerve.

It’s also known as an “eye stroke” or anterior ischemic optic neuropathy (AION).

Symptoms of ION include:

  • Sudden, painless vision loss in one or both eyes
  • Loss of visual acuity or visual field
  • Afferent pupillary defect
  • Abnormal-appearing optic nerve
  • Permanent blindness

In the current case, the authors present a 73-year-old woman who developed a headache, myalgia, scalp tenderness, and jaw claudication just four days after her seventh dose of Covid mRNA shots.

The patient experienced severe visual disturbances a month after receiving her seventh injection.

While seven shots may sound excessive, those who follow the official advice of the U.S. Centers for Disease Control and Prevention (CDC) would now be taking their tenth dose.
