To evaluate the potential of OCT angiography to detect and characterize choroidal neovascular networks in eyes with in chronic central serous chorioretinopathy (CSC).
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.
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.
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.
