Non‐invasive retinal imaging of central serous chorioretinopathy

Abstract Purpose Central serous chorioretinopathy leads to a serous detachment of the retina and a deterioration of visual acuity, contrast sensitivity and color vision. This is due to a leakage of serous fluid into the subretinal space through a defect in the retinal pigment epithelium. Methods A female patient aged 34 years experienced a drop in best corrected visual acuity to 20/40 with mild hyperopization and dyschromatopsias for two weeks. The diagnosis of a central serous chorioretinopathy was substantiated by optical coherence tomography (Stratus OCT, Zeiss Meditec, Jena, Germany) and infrared autofluorecence imaging (HRA classic; Heidelberg Engineering, Heidelberg, Germany). The patient additionally underwent retinal imaging by the Retinal Function Imager (RFI, Optical Imaging, Rehovot, Israel). Results The findings suggest that the technique applied by the Retinal Function Imager can be helpful to diagnose central serous chorioretinopathy and to visualize abnormal areas at the level of retinal pigment epithelium in a non‐invasive manner. This finding may suggest that the Retinal Function Imager was able to demonstrate a small motion in the subretinal space, originating at the site of detached retinal pigment epithelium. The finding fits with the observation of “smoke stacks” of fluorescein seen in patients with central serous chorioretinopathy when conventional fluorescein angiography is used. Conclusion The technique applied by the Retinal Function Imager can be helpful to diagnose central serous chorioretinopathy and to visualize abnormal areas at the level of retinal pigment epithelium in a non‐invasive manner. This finding may suggest that the Retinal Function Imager was able to demonstrate a small motion in the subretina
