| Abstract |
Damage tests were conducted on rabbit and monkey eyes and threshold values were determined for the retinal hazard range of wave lengths of 400-1,200nm; several types of lasers normally used in medicine, industry and research were tested at different energies and exposure durations. The reproduction of the "worst-case" exposure situation was ensured by the test apparatus, and threshold value determinations were based on the ophthalmoscopic visibility of retinal lesions. The experimental results supported the current laser safety limits (ANSI, ACGIH, IEC) but indicated that more work is required for a better understanding of the implications of delayed effects. Mathematical thermal modelling would allow a better confirmation that the damage is thermal or thermochemical. |
