In vivo corneal confocal microscopy aided by optical coherence tomography

In vivo corneal confocal microscopy and its operability in scientific as well as in clinical applications is often impaired by the lack of information on imaging plane position and orientation inside the cornea during patient’s examination. To overcome this hurdle, we have developed a novel corneal imaging system based on a commercial scanning device and a modified Rostock Cornea Module. The presented preliminary system produces en face images by confocal laser scanning microscopy and sagittal cross-section images by optical coherence tomography simultaneously. This enables imaging guidance during examinations, improved features for diagnostics along with thickness measurements of the cornea as well as corneal substructures from oblique sections.
