Background: To evaluate functional and structural abnormalities in patients with acute central serous chorioretinopathy (CSC) with multifocal electroretinography (mfERG) and enhanced depth imaging optical coherence tomography (EDI-OCT)
Methods: This prospective observational study included 57 patients with unilateral CSC. Both eyes underwent mfERG and EDI-OCT. Peak amplitudes and implicit times of the first kernel responses were analyzed and compared with those in 25 age-matched normal controls. Correlational analyses were performed between the mfERG results and EDI-OCT parameters. The thicknesses of the central retina, subretinal fluid, and choroid was measured at baseline and 3 months later.
Results: Compared with the normal controls, the amplitude and implicit time on mfERG were significantly impaired in the area with serous retinal detachment (SRD). The P1 amplitude and implicit time of the areas beyond the SRD were also found to be significantly impaired in the affected eyes. Eyes with a greater reduction in SRD had a less impaired mfERG response in fellow eyes than those whose retinal detachments were not spontaneously decreased by more than 90% after 3 months. Correlational analysis did not reveal any significant correlations between mfERG values and OCT parameters except for central choroidal thickness. The subfoveal choroidal thickness was negatively correlated with the mfERG parameters.
Conclusions: The findings of this study indicate diffuse functional impairment in acute CSC involving both eyes and areas beyond the SRD. The retinal response of the unaffected eye was associated with regression of SRD. Functional retinal abnormality was found to correlate with pathological changes in the choroid.
