Abstract
Purpose :
To evaluate the potential of OCT angiography to detect and characterize choroidal neovascular networks in eyes with in chronic central serous chorioretinopathy (CSC).
Methods :
This study was designed to compare OCT angiography with conventional angiography in a cohort of patients affected by chronic CSC. Patients underwent fluorescein (FA) and indocyanine green (ICGA) angiography, swept source OCT and OCT angiography (Triton, Topcon, Japan). A qualitative analysis of the entire imaging data was performed.
Results :
Fifteen eyes of 10 patients were evaluated. Mean age was 56.1±7.7 years. FA and ICGA were able to detect abnormal subfoveal choroidal neovascular networks in two eyes (13%). OCT angiography detected choroidal neovascular networks in 7 out of 15 eyes (47%). Two cases showed an indistinct tangled pattern, 3 neovascular networks appeared as a classic “ball of wool” pattern, and 2 eyes exhibited a pruned tree pattern.
Conclusions :
OCT angiography is able to detect abnormal neovascular networks which are not identifiable with conventional angiographic modalities. Neovascular lesions in chronic CSC may be more frequent than expected.
