Hydroxychloroquine, retinal toxicity, and COVID-19
Hydroxychloroquine is being promoted as a treatment or prevention for COVID-19 based on questionable evidence. The long-term impact of hydroxychloroquine on the retina introduces another reason to be cautious about its use outside of clinical trials.

The p-hackers toolkit
P-hacking is a common and persistent problem in research, with impacts on the scientific literature, reporting, and practice in medicine. But what is it, really?

Patients Blinded by Stem Cell Therapy: FDA (and consumers) win a legal victory!
The Food and Drug Administration just won a court case supporting the agency's ability to regulate stem cell clinics that rely on client-derived adipose tissues. This is a win for consumer protection, though too late to help those already harmed.

Macular Degeneration, Genes, and Grandma’s Vitamins: To test or not to test?
Is genetic testing necessary to optimize treatment for patients with a potentially blinding eye disease? The stakes are high and the answer depends on which of the two feuding, financially-conflicted groups you believe. In the end, the best evidence wins!

Patients blinded by stem cell therapy: more egregious than you imagined

Anti-VEGF treatment of Macular Degeneration: Science-Based Success
Let's celebrate some good science with a story about some evidence-based treatments for macular degeneration!
Andrew Weil Flirts with Evidence Based Medicine
