Abstract

The evaluation of the safety of high-power light sources requires a broad understanding of both thermal and photochemical damage mechanisms in retinal tissue. A comprehensive model which can support complex spectral, temporal and spatial dependency of these effects is essential to evaluation of existing safe exposure limits across a broad parameter space. We present an initial implementation of a thermal damage model along with validating experiments. The model is capable of examining a wide parameter space and is highly extensible to the examination of a variety of damage mechanisms. Also presented is a recent study which examines the effects of a filtered Xenon arc lamp for an exposure duration of ten seconds. This data is examined in relation to the model and a number of historical data points. We also examine exposure limits from the American Council of Government Industrial Hygienists as they apply to these sources.
