People taking antibiotics called fluoroquinolones may be at a small risk of an eye condition called retinal detachment, a new study suggests. These commonly prescribed antibiotics, used to fight a variety of bacterial infections, have been linked to other eye problems, including corneal perforations, optic neuropathy and retinal hemorrhages. But this is the first study that has linked them to retinal detachment, a serious medical emergency that may lead to blindness, the Canadian researchers said.
