Abstract

Purpose. To investigate the prevalence and characteristics of focal choroidal excavation (FCE) concurrent with central serous chorioretinopathy (CSC) using multimodal imaging. Methods. This was a retrospective single-institution study. Clinical features and multimodal imaging findings were analyzed in eyes with CSC and FCEs, using imaging methods including optical coherence tomography (OCT), OCT angiography (OCTA), fluorescein angiography (FA), indocyanine green angiography (ICGA), fundus autofluorescence (FAF), and multispectral imaging. Results. Seventeen patients (4.8%) with 21 FCEs (19 eyes) were found among 351 consecutive Chinese patients with CSC. Chronic CSC represented 47.1% of those cases. Window defects in 12 lesions identified through FA and hypoautofluorescence in 13 lesions identified through FAF revealed retinal pigment epithelial attenuation. Choroidal hemodynamic disturbances characterized by localized filling defects at the excavation and circumferential hyperperfusion were validated by both ICGA and OCTA, which were similar to the angiographic features of normal chronic CSC. The hyperreflective tissue beneath FCE, observed on B-scan OCT, presented as intensive choroidal flow signals on OCTA. Conclusions. FCE is not uncommon in patients with CSC. Multimodal imaging suggested that the aberrant choroidal circulation might be a contribution factor for leakage from the dysfunctional retinal pigment epithelium at the area of excavation.
