It is currently difficult to obtain high resolution images of the embedded microcapillary network of the LC using conventional imaging techniques. In this study, an optical resolution photoacoustic microscopy (OR-PAM) system was used for imaging lamina cribrosa of an ex vivo porcine eye. Extrinsic contrast agent was used to perfuse the eye via its ciliary arteries. The OR-PAM system have a lateral resolution of 4 μm and an axial resolution of 30 μm. The high resolution system could able resolve a perfused LC microcapillary network to show vascular structure within the LC thickness. OR-PAM could be a promising imaging modality to study the LC perfusion and hence could be used to elucidate the hemodynamic aspect of glaucoma.||URI:||https://hdl.handle.net/10356/87994
