New publication on three-dimensional light field imaging
New publication on three-dimensional light field imaging of the human retina and depth measurement of the optic disc.
In the publication "3D retinal imaging and measurement using light field technology" we established for the first time a three-dimensional imaging of the ocular fundus without the use of laser technologies. Light-field fundus photography has the potential to be a new milestone in ophthalmology. Up-to-date publications show only unsatisfactory image quality, preventing the use of depth measurements. We show that good image quality and, consequently, reliable depth measurements are possible, and we investigate the current challenges of this novel technology. The measurement of the depth of the optic nerve head is in good agreement with both model measurements and established optical coherence tomography (OCT). Thus, the new technology can be a contribution to early diagnosis of e.g. glaucoma.
