Kurzfassung englisch:
Numerous ocular diseases, such as diabetic retinopathy, glaucoma, and macula degeneration, are related to changes in retinal blood flow. Animal models allow the study of various ocular diseases under controlled conditions and, hence, are required to gain a deeper understanding of the correlation between the dysfunction in perfusion and the pathological mechanisms underlying these diseases. Recently, a lot of research has been done in the field of Optical Coherence Tomography, to allow the non-invasive measurement of changes in retinal perfusion.
This presentation illustrates the basic physical principles as well as the setup of a Doppler Fourier-Domain Optical Coherence Tomograph combined with a commercial Retinal Vessel Analyzer. Special techniques are introduced to detect velocity changes in small capillaries with diameters in the range of 10 µm. Results achieved by this novel measurement system are presented and discussed.
