Moderator Rebecca Soares, MD, and panelists Matt Starr, MD, and Nikisha Kothari, MD, review a decade-long case control-control study assessing risk of AMD in non-diabetic patients who have been taking metformin for any reason. They ask whether the study's blindspots undercut its findings, and speculate what other questions further research could answer.
