Top 10 Lifestyle Interventions for Glaucoma

#8: Ginkgo Biloba — Supporting Blood Flow to the Optic Nerve

Why This Matters for Glaucoma

Ginkgo biloba may improve ocular blood flow and has been studied for slowing visual field loss.

Some forms of glaucoma are strongly linked to vascular dysfunction, not just pressure.

What the Science Shows

  • Improved blood flow:
    Ginkgo may enhance circulation to the optic nerve.
  • Potential neuroprotective effects:
    Some studies suggest slower visual field progression.

Why Does This Help?

  • Antioxidant properties
  • Improved microcirculation
  • Reduced oxidative stress

What to Watch For

  • Possible interactions (e.g., blood thinners)

What Should You Do?

  • Discuss with your physician before starting

  • Use standardized extracts

Bottom Line

  • Ginkgo may support blood flow and optic nerve health, particularly in select patients.
