The association between self-reported glaucoma and ginkgo biloba use

Area of Science:

• Ophthalmology
• Integrative Medicine
• Public Health

Background:

• Glaucoma is a leading cause of irreversible blindness worldwide.
• Ginkgo biloba extract (GBE) is a popular herbal supplement with purported antioxidant and circulatory benefits.
• Previous research on GBE and glaucoma has yielded mixed results.

Purpose of the Study:

• To investigate the association between self-reported Ginkgo biloba extract (GBE) use and the prevalence of glaucoma.
• To determine if GBE use is a significant factor in individuals diagnosed with glaucoma.

Main Methods:

• Utilized data from the 2002 National Health Interview Survey, a nationally representative sample.
• Analyzed self-reported GBE use within the past 12 months and glaucoma diagnosis.
• Employed crude and adjusted statistical models to assess the association, controlling for demographic and medical factors.

Main Results:

• Individuals with glaucoma were 26% less likely to report GBE use, but this difference was not statistically significant.
• After adjusting for confounding variables, no significant difference in GBE use was observed between glaucoma patients and controls.
• The study did not find a statistically significant association between GBE use and glaucoma prevalence.

Conclusions:

• Current findings do not support a significant relationship between recent Ginkgo biloba extract (GBE) use and glaucoma.
• Replication in prospective studies is recommended to validate these results.
• The efficacy of GBE as a treatment for glaucoma requires further investigation.
