Abstract
Purpose :
To evaluate the OCT angiography (OCT-A) characteristics in patients with chronic central serous chorioretinopathy (CSCR) complicated with polypoidal choroidal vasculopathy (PCV).
Methods :
12 eyes of 10 consecutive patients with an history of chronic CSCR have been evaluated with complete ophthalmological examination including fluorescein angiography (FA) and indocyanine green angiography (ICGA) and SD-OCT (HRA+OCT Spectralis Heidelberg), that revealed the presence of polypoidal lesions with their neovascular network. The patients were then scanned with OCT-A, using AngioVue technologies (Optovue Inc), in order to define the clinical characteristics in those lesions previously observed on multimodal imaging. The images were then analyzed by three different retinal specialists.
Results :
Outer retina and choriocapillaris segmentation on OCT-A analysis confirmed the presence of the neovascular network in 100% of the eyes, while the polyps were seen in 8 eyes (66,6%) and not detectable in 4 eyes (33,3%), on the basis of the ICGA matching images. In the majority of the cases the polyp-lesion appeared as an hyperflow aneurysmatic dilatation surrounded by a dark halo. The observers were in agreement in 75% of cases.
Conclusions :
OCT-A appears to be less precise compared to ICGA in order to detect the presence of the polyps although the neovascular network was always detectable with both machines in patients with PCV complicating chronic CSCR.
