Eye Stroke vs Brain Stroke: Understanding the Differences

Eye strokes and brain strokes both involve blocked blood flow, but they affect different parts of the nervous system. Learn how they compare and how Dr. Andy Rosenfarb treats eye strokes holistically.

Eye Stroke vs Brain Stroke

Both eye strokes and brain strokes occur when blood flow is blocked, depriving cells of oxygen.
But they affect different parts of the nervous system — and their symptoms and treatments differ.

Dr. Andy Rosenfarb explains:

“An eye stroke is like a stroke of the optic nerve or retina. A brain stroke affects brain tissue. Both are serious, both are vascular, and both require immediate attention.”


What Is an Eye Stroke?

  • Affects the retina or optic nerve.
  • Caused by blocked arteries or veins, or reduced circulation to the optic nerve.
  • Leads to sudden, painless vision loss in one eye.

Types include:


What Is a Brain Stroke?

  • Affects the brain.
  • Caused by blocked or ruptured cerebral arteries.
  • Leads to neurological symptoms such as:
    • Weakness or paralysis
    • Difficulty speaking
    • Loss of balance or coordination
    • Severe headache or dizziness

Shared Risk Factors

Both eye and brain strokes are strongly tied to vascular health:

  • High blood pressure
  • Diabetes
  • High cholesterol
  • Carotid artery disease
  • Smoking
  • Sleep apnea
  • Heart disease

How Symptoms Differ

  • Eye stroke: Sudden vision loss, blurred vision, or blind spots (often painless).
  • Brain stroke: Sudden weakness, slurred speech, dizziness, facial droop, confusion.

Conventional Medicine Approaches

  • Eye strokes: Blood thinners, injections, laser, or simply “watch and wait.”
  • Brain strokes: Emergency clot-busting drugs (tPA), surgery, rehab therapy.

Holistic & Functional Approaches

Dr. Rosenfarb emphasizes integrative therapies for eye strokes:

Acupuncture

Stimulates circulation and reactivates dormant retinal or optic nerve cells.

Hyperbaric Oxygen Therapy

Delivers oxygen directly into oxygen-starved tissues.

Alternating Current Microstimulation (ACS-3000)

Encourages repair and function of damaged nerve cells.

Low-Level Laser Therapy

Supports mitochondrial repair and reduces oxidative stress.

Nutrition & Lifestyle

Antioxidants, enzymes, omega-3s, stress management, and qigong help reduce systemic risk for both eye and brain strokes.


Can an Eye Stroke Predict a Brain Stroke?

Yes. An eye stroke is often considered a warning sign of vascular disease.
Patients with an eye stroke should undergo systemic evaluation for carotid artery disease, heart disease, and stroke risk factors.


Patient Story

A 64-year-old man experienced sudden loss of vision in one eye from a BRVO. Further testing revealed carotid artery plaque that also put him at risk of a brain stroke. After starting acupuncture, supplements, and lifestyle changes, he stabilized his vision and reduced his overall vascular risk.

This shows how treating an eye stroke holistically can also protect brain health.
