Identification of intraretinal neovascularization by high-speed indocyanine green angiography in idiopathic perifoveal telangiectasia.
Rapid advances in imaging technology have dramatically improved our understanding of the flow patterns of intraretinal circulation in normal and diseased states. To identify the angiographic features and flow pattern of retinal circulation in a patient with type 2 idiopathic perifoveal telangiectasia, dynamic simultaneous high-speed videoangiography using confocal scanning laser ophthalmoscopy was performed. This diagnostic tool provides enhanced anatomic resolution of retinal arterioles otherwise poorly defined by regular fluorescein and static indocyanine green angiography. High-speed indocyanine green angiography demonstrated dynamic flow abnormalities such as intraretinal neovascular complex and retino-retinal anastomosis in idiopathic perifoveal telangiectasia.
