Abstract

We present, to the best of our knowledge, the first label-free, non-contact, in vivo imaging of the ocular vasculature using photoacoustic remote sensing (PARS) microscopy. Both anterior and posterior segments of a mouse eye were imaged. Vasculature of the iris, sclera, and retina tissues were clearly resolved. To the best of our knowledge, this is the first study showing non-contact photoacoustic imaging conducted on in vivo ocular tissue. We believe that PARS microscopy has the potential to advance the diagnosis and treatment of ocular diseases.
