Representative images obtained with two different forms of optical coherence tomography. Chronic unilateral central serous chorioretinopathy, in the left eye, with onset 12 months prior to study enrollment. Enhanced depth imaging optical coherence tomography (EDI-OCT) (Top). Swept-source OCT (SS-OCT) image (Bottom). Both images were obtained on the same day. The subfoveal choroidal thickness was measured as the distance between the outer border of the retinal pigment epithelium-Bruch’s membrane complex and the chorioscleral border under the fovea. Subfoveal choroidal thickness was 588 μm in EDI-OCT (Top), and 587 μm in SS-OCT (Bottom). Serous retinal detachment was measured between the outer surface of the neurosensory retina and the retinal pigment epithelium, and the height was 164 μm in SS-OCT (Bottom).
