In vivo photoacoustic chorioretinal vascular imaging in albino m...

Photoacoustic ophthalmoscopy (PAOM) is a novel imaging modality, which is capable of non-invasively detecting optical absorption properties in the retina. We visualize the microvasculature in retina and choroid in albino mouse using PAOM guided by spectral-domain optical coherence tomography. Since albino mouse characterizes by lacking melanin in retinal pigment epithelium (RPE), PAOM illumination laser can penetrate through the RPE onto choroid, and consequently provides volumetric visualizatio
