Using the CANON CG 6 60 Z wide-angle fundus camera, fluorescein angiographic examinations of the fundus periphery were performed on 90 diabetic patients presenting with exudative diabetic maculopathy. The peripheral angiogram demonstrates that perimacular hyperpermeability - the main cause of diabetic maculopathy - is preceded by extensive disturbances of capillary perfusion in the midperiphery.
