Abstract

In this work, we show the capability of laser optoacoustics to localize the position of the ciliary body on enucleated porcine and rabbit eyes. Our findings correspond well with histological sections of the measured area. Different wavelengths for an optoacoustical detection system in combination with laser cyclophotocoagulation have been compared taking grayscale images of the region of interest of rabbit and porcine eyes for various wavelengths in the NIR spectral range. Additionally, the changes in the optical properties of the tissue induced by coagulation with a diode laser were observed. First online measurements of the changes due to coagulation show that the method of laser optoacoustics is suitable for an online therapy control system.
