Laser-induced thermal damage to the retina
Speaker:Rahat Ullah (Seibersdorf Labor GmbH, Seibersdorf/NÖ)
Abstract:Excised bovine eyes are used as models for threshold determination of laser-induced thermal damage to the retina for varying spot sizes and exposure durations. The damage thresholds as determined by fluorescence viability staining compare very well with prediction of an extended computer model developed by this group. Both models threshold data compare well with the already published data of the rhesus monkey available in this time domain. The dependence of thermal damage thresholds on pulse durations for time between 1 ms -- 1 s is seen. We conclude retinal pigment epithelium (RPE) cell damage as the primary damage mechanism. Based on these findings a validated computer model provides the basis for safety analysis of more complicated retinal exposures scenarios and will be used in future for calculating damage thresholds of more complex laser beam parameters.
