Abstract

In this work, the feasibility of optoacoustic tomography to act as diagnostic tool in laser cyclophotocoagulation was investigated. The experiments were performed with enucleated porcine and rabbit-eyes. The absorption of short laser pulses in the wavelength range between 750 and 1000 nm generated thermoelastic stress waves in the ciliary muscle and the underlying pigmented epithelial layers. These stress transients were detected at the surface of the sclera with piezoelectric transducers in order to analyze the structure. Depths of the ciliary body could be determined at different distances from the corneoscleral limbus. Furthermore, changes in the optoacoustic signal due to coagulation with a diode laser using typical therapeutical parameters could be observed.
