Abstract: In order to understand the pathophysiology of glaucoma, Lamina cribrosa (LC) perfusion needs to be the subject of thorough investigation. 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.
