Focal Choroidal Excavation in Eyes With Central Serous Chorioretinopathy – Corrected Proof
Purpose: To study the prevalence and 3-dimensional (3-D) tomographic features of focal choroidal excavations in eyes with central serous chorioretinopathy (CSC) using swept-source optical coherence tomography (OCT).Design: Prospective, cross-sectional study.Methods: We examined 116 consecutive eyes with CSC with a prototype 3-D swept-source OCT. 3-D images of the shape of the macular area, covering 6 × 6 mm2, were reconstructed by segmentation of the outer surface of the retinal pigment epithelium (RPE).Results: The 3-D swept-source OCT detected focal choroidal excavations in 9 eyes (7.8%). The 3-D scanning protocol, coupled with en face scans, allowed for clear visualization of the excavation morphology. In 5 (Read more...)
