Smokestack leak on indocyanine green angiography during CSC:
The present case has been reported in the Indian Journal of Ophthalmology.

Two patients of acute central serous chorioretinopathy (CSC) underwent simultaneous fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) (Heidelberg Spectralis, Heidelberg, Germany) using 25 mg ICG dye and 3 ml of 20% fluorescein sodium. A typical Smokestack leak (SSL) on FFA was seen in both the cases. Interestingly, the ICGA also showed an SSL.

The SSL seen on ICGA, however, appeared later than that of FFA. Areas of choroidal hyperpermeability were seen in addition, in the late phases of ICGA in both the cases. Spectral domain optical coherence tomography (OCT) revealed a large neurosensory detachment (NSD) in both the cases. Irregular, flat pigment epithelial detachments (PEDs) and a dip in the neurosensory retina were also seen on OCT through the area of the leak in both eyes.
