While super-resolution-microscopy has become widely available, its application in clinical context is still mostly restricted to cultivated cells. We present the application of (3+1)D(3 excitation/emission spectra) Structured Illumination Microscopy to clinical research on extracted tissues as well as quantitative analysis of over 300 human RPE cells and their granules (intracellular particles) regarding connections to age related macular degeneration. Autofluorescencence behaviour is a characteristic hallmark for several chorioretinal conditions, so SIM offers potential for further clinical imaging at illumination powers that allow application to living patients (ongoing clinical study).
