Paper Abstract

Determination of the precise location and degree of condition of the Choroidal neovascularization (CNV) lesion is essential for diagnosation Neovascular age-related macular degeneration (AMD) and evaluation the efficacy of treatment. Given the complimentary contrast mechanisms of Photoacoustic microscopy (PAM) and Optical coherence tomography (OCT), the combination of PAM and OCT imaging could potentially provide much sensitive and specific detection of CNV. In this paper, we validated the opportunity to evaluate the information of laser-induced CNV and presented the in vivo time-serial evaluation of the CNV by simultaneously using PAM and OCT techniques. In vivo PAM and OCT examination was performed after laser photocoagulation applied to the rat fundus at days 1, 3, 5, 7, 14. Time-serial results showed that CNV in rats increased to its maximum at day 7 and decreased at day 14. Evolution of CNV information was given in PAM images with a high contrast and details of high axial resolution OCT images were simultaneously given to show the hyperreflective reaction progress.
