Central serous chorioretinopathy (CSC) is believed to be due to abnormal and increased choroidal hyperpermeability and is clinically represented as increased choroidal thickness on optical coherence tomography (OCT). Hyper-reflective foci (HRF) are observed within the choroid in CSC, but the significance of HRF in CSC remains unclear. The aim of this study was to assess the factors associated with the presence of HRF in recurrent and chronic CSC.
We retrospectively graded the enhanced depth imaging (EDI) scans of consecutive patients with CSC and evaluated the association of HRF with demographic data, subfoveal thickness of the choroid, presence or absence of the choriocapillaris layer and integrity of the ellipsoid layer.
We evaluated the EDI scans of 126 eyes of 99 patients with CSC with a mean age of 53.48 (±10.54) years. CSC was defined as recurrent in 36(29%) and chronic in 90 (71%) eyes. The mean subfoveal choroidal thickness was 403.37(±125.36)µm. HRF were more prevalent with increasing age (p=0.01). HRF were observed in 36(28.57%) and ellipsoid layer disruption was noted in 41(32.54%) eyes. HRF were present in 46.34% (p=0.003) of eyes with ellipsoid layer disruption. There was no significant association between HRF and gender (p=0.37), or absence of choriocapillaris (p=0.84).
Choroidal HRF in CSC were associated with the disruption of the photoreceptor layer suggesting that HRF may be a surrogate marker of poor photoreceptor function.
