title: Cortical blindness after cardiac catheterization: effect of rechallenge with dye.
abstract: Transient cortical blindness (CB) is a rare complication of dye usage during cardiac catheterization, percutaneous transluminal coronary angioplasty (PTCA) or directed coronary atherectomy (DCA), and is limited to few case reports. In this paper, we are describing three such cases of CB who, upon reexposure to dye during subsequent cardiac catheterization, did not develop CB. To our knowledge, the consequences of reexposure of these patients to dye has not been described in literature.
