What Does NAION Stand For?

NAION stands for Non Arteritic Anterior Ischemic Optic Neuropathy

NAION, or Non Arteritic Anterior Ischemic Optic Neuropathy, is a medical condition characterized by sudden vision loss due to insufficient blood flow to the optic nerve, specifically the anterior portion. This condition typically occurs without inflammation of the arteries and is often associated with risk factors such as diabetes, hypertension, and sleep apnea. Symptoms may include blurred or dimmed vision in one eye, and while the exact cause is not fully understood, it is believed to involve compromised blood supply. Prompt evaluation by an eye care professional is essential for diagnosis and management.
