Determinación del espesor coroideo macular mediante tomografía de dominio espectral sin Enhanced Depth Imaging (EDI) en coriorretinopatía central serosa aguda

Abstract

Objective: To evaluate the utility of Spectral Domain Optical Coherence Tomography (SD-OCT) Cirrus without Enhanced Depth Imaging (EDI) to measure choroidal thickness, in cases of acute central serous chorioretinopathy. Methods: Longitudinal prospective study of patients with acute central serous chorioretinopathy (CCS), seen in April 2013 in HUNSC. Each patient underwent a single HD 5 Line Raster of 9 mm. The choroid was studied by two observers independently and it was measured manually at 500 µm intervals. Results: 10 eyes of 10 patients with acute CCS were included, 80% of patients were men. The mean age was 47±14.41 years and the mean axial length was 22.94±0.26 mm. In 80% of cases it was possible to measure at least 8 points. Only in 1 case (10%), measuring the choroid in any of its points was not possible. Subfoveal choroidal thickness could be measured in 40-50% of cases, depending on the observer. Conclusions: The average subfoveal choroidal thickness was 351.75 ± 80.57 microns. The SD-OCT Cirrus without EDI (Carl Zeiss Meditec, Dublin, CA) has shown to have limited utility for the measuring of choroidal thickness in acute CCS. It can be measured in 50% of cases in more than 8 points, with a minimal inter-observer variability.
