FLUOROQUINOLONES USE AND RETINAL DETACHMENT

Fluoroquinolones are one of the most commonly prescribed classes of antibiotics. Ciprofloxacin, levofloxacin, moxifloxacin and gemifloxacin are widely used for the treatment of various types of bacterial infections. Their broad-spectrum antibacterial coverage and high-tissue distribution provide advantage for prescribing in variety of community-acquired infections. Though it is well tolerated and has good safety index, they are found to be associated with a wide range of adverse events such as dysglycemia1, cardiac arrhythmia2, and neuropsychiatric events3. Fluoroquinolones also have been linked to several forms of ocular toxicity such as corneal perforations4, optic neuropathy5, and retinal hemorrhages6. They have also been issued to cause tendon rupture7, which raises concerns for the effect of these drugs on connective tissue in the eye. The putative mechanism behind a possible fluoroquinolone-induced retinal detachment may be through the destructive effect of the drugs on collagen and connective tissue8. Collagen fibers play a pivotal role in the structure and integrity of the vitreous body9. Thus, breakdown of collagen, possibly secondary to fluoroquinolone therapy, may promote the development of posterior vitreous detachment, leading to an increased risk of retinal detachment. Retinal detachment is a serious medical emergency that may lead to irreversible vision loss. Up to 40% of those who experience this event may experience significant loss of visual acuity despite surgical intervention10. In a nested case-control study of a cohort of patients in British Columbia, Canada, who had visited an ophthalmologist between January 2000 and December 2007. Overall, the annual incidence of retinal detachment in the United States is estimated to be 12 per 100,000 patients. Given an exposure prevalence of about 10 percent and assuming a similar risk increase in the general population, the study authors estimate the population-attributable risk to be about 4 percent. Thus, they estimate that 1,440 cases of retinal detachment diagnosed each year in the United States may be attributed to oral fluoroquinolone use11. In another cohort study based on the general Danish population, oral fluoroquinolone use was not associated with increased risk of retinal detachment. Given its limited power, this study can only rule out more than a 3-fold increase in the relative risk associated with current fluoroquinolone use; however, any differences in absolute risk are likely to be of minor, if any, clinical significance12. Given that oral fluoroquinolones are one of the most prescribed classes of antibiotics, it is important that their full risk and safety profile be known.
