Paper Abstract

Retinal photocoagulation was observed with repetitive short laser pulses of a Nd:YAG laser. The number of pulses applied was 10 and 500. Threshold curves for angiographic and ophthalmoscopical visibility as well as for bleeding were established. No macroscopic disruptive effects were observed, however macroscopic visible bubble formation occurred regularly at energy levels 2 times above ophthalmoscopical visibility. Bubble formation as primary interaction mechanism due to local overheating of single melanin granules is postulated.
