BACKGROUND The aim of this study is to determine the differences in optical coherence tomography angiography (OCTA) features of acute Vogt-Koyanagi-Harada disease (VKH) and acute central serous chorioretinopathy (CSC). Clinical and imaging data of patients with acute CSC and VKH in a tertiary-care institute were analyzed. Multimodal imaging including fluorescein angiography, indocyanine green a...

We describe features of a circumscribed choroidal hemangioma (CCH) treated with photodynamic therapy (PDT) by means of optical coherence tomography angiography (OCT-A). A 40-year-old man had a complaint of decreasing visual acuity in his left eye for 10 days. A diagnosis of CCH was confirmed by fundus examination, fluorescein angiography, and indocyanine green angiography. An OCT-A study of cho...

This 47 year old female developed the new onset of a polypoidal subretinal neovascular membrane in the left eye 13 years after having polypoidal choroidal vasculopathy (PCV) treated in the right eye. The indocyanine green (ICG) angiography of the left eye at initial presentation showed a normal choroidal vascular pattern without PCV. The new development of a PCV complex on ICG angiography demon...

Surgical microscope-integrated intraoperative angiography with intra-venous injection of indocyanine green (ICG) has been widely used during bypass or aneurysm surgery. Instead of intra-venous injection of ICG, we describe a case of intraoperative video angiography with intra-arterial injection of ICG in cerebral arteriovenous malformation (AVM) surgery. During the surgery, we injected ICG thro...

Fluorescence angiography was first used by ophthalmologists to measure retinal blood flow by using the fluorescent dye fluorescein. Feindel et al.1,2 were the first to apply the concept of fluorescence angiography to the intraoperative visualisation of cerebral vertebral arteries and cerebral microcirculation in patients undergoing neurosurgical procedures.3,4 With the use of indocyanine green ...

1. The validity of a two-compartment pharmacokinetic model for the estimation of the hepatic extraction ratio of Indocyanine Green was tested in six patients with cirrhosis of the liver. 2. No agreement was found between the value of the hepatic extraction ratio measured directly and that calculated using the two-compartment model. 3. To investigate the reasons for the failure of the model, an ...
