To the Editor: The nested case-control study by Dr Etminan and colleagues1 demonstrated an association between systemic fluoroquinolone use and episodes of treatment for retinal detachment. As the authors stated, association does not imply causation. Although the adjusted rate ratios and confidence intervals were noteworthy, several important confounding factors need to be considered.
