MYTHS & FACTS

Myths and Facts

NAION stands for Non-Arteritic Anterior Ischemic Optic Neuropathy, a condition that affects the optic nerve. Let me provide you with some common myths and facts about NAION:

Myths:

  1. NAION only affects older people. Fact: While it’s more common in older adults, NAION can occur at any age.
  2. NAION always leads to complete blindness. Fact: The degree of vision loss varies; some people may experience partial vision loss.
  3. NAION is always preventable. Fact: While some risk factors can be managed, not all cases are preventable.
  4. NAION affects both eyes simultaneously. Fact: It typically affects one eye at a time, though there’s a risk of it occurring in the other eye later.

Facts:

  1. NAION is caused by reduced blood flow to the optic nerve.
  2. Risk factors include high blood pressure, diabetes, high cholestrol, sleep apnea, possiby with use of ED drugs, possibly from using Ozempic.
  3. Symptoms often include sudden vision loss, typically noticed upon waking.
  4. There’s currently no proven effective treatment to reverse the vision loss caused by NAION.
  5. Managing underlying health conditions may help reduce the risk of NAION in the unaffected eye.
  6. NAION is different from arteritic AION, which is associated with giant cell arteritis and requires immediate treatment.
  7. The “disc at risk” or “crowded disc” is an anatomical feature that may predispose some individuals to NAION.
  8. Vision loss from NAION is usually permanent, but some patients may experience slight improvement over time.

Here’s an overview of myths and facts about monocular vision, low vision, and blindness, addressing common misconceptions and providing accurate information:

  1. Myth: People with vision loss or blindness have heightened other senses. Fact: While some individuals may develop increased sensitivity in other senses, this is not automatic or universal. It often results from increased focus and practice using non-visual senses.
  2. Myth: All visually impaired people see total darkness. Fact: Vision loss exists on a spectrum. Many people with low vision or legal blindness retain some degree of sight, such as light perception or limited visual field.
  3. Myth: People with monocular vision lack depth perception. Fact: While stereoscopic vision is impaired, many with monocular vision develop alternative depth cues like motion parallax and can still judge distances effectively.
  4. Myth: Blind people can’t use computers or smartphones. Fact: Assistive technologies like screen readers, voice commands, and braille displays enable many visually impaired individuals to use digital devices proficiently.
  5. Myth: All visually impaired people read braille. Fact: Only a small percentage of visually impaired people are fluent in braille. Many use other adaptive techniques or retain enough vision to read large print.
  6. Myth: People with low vision or blindness can’t live independently. Fact: With proper training and adaptive techniques, many visually impaired individuals lead fully independent lives, including working and traveling alone.
  7. Myth: Vision loss only affects older adults. Fact: Vision impairment can occur at any age due to various conditions, injuries, or genetic factors.
  8. Myth: People with monocular vision can’t drive. Fact: Many individuals with monocular vision can and do drive safely, often with minimal restrictions.
  9. Myth: All visually impaired people use guide dogs. Fact: While guide dogs are helpful for some, many visually impaired individuals use white canes or navigate independently without aids.
  10. Myth: Low vision can always be corrected with glasses. Fact: While glasses can help some people with low vision, many conditions causing vision loss cannot be fully corrected with standard eyewear.

These facts aim to counter stereotypes and provide a more accurate understanding of the diverse experiences of people with various forms of vision impairment.
