[Three-dimensional imaging in central serous chorioretinopathy].
BACKGROUND
Conventional optical coherence tomography (OCT) has brought new insights to retinal diagnostics, but it is restricted due to its low scanning speed and limited resolution. In this study, high-resolution raster scanning OCT (HR-OCT) was used to identify typical changes in central serous chorioretinopathy (CSC).


METHODS
Fifteen consecutive patients with acute CSC were imaged using HR-OCT with an axial image resolution of 6 mum. The scanned area measured 6x6 mm2. Three-dimensional (3D) evaluation was performed using various analysing programmes.


RESULTS
Topographic changes in CSC could be visualised with 3D reconstructions in all locations. Retinal thickness was measured with the automatic segmentation mode and quantified precisely. Results were presented in 2D and 3D maps. En-face imaging as a modality to present an integrative overview showed specific alterations in CSC.


CONCLUSIONS
HR-OCT was able to provide essential additional information about CSC when combined with appropriate analysing programmes, allowing the identification of typical differences. Aside from precise volumetric measurements, exact localisation of pathological deviations could be achieved.
