Abstract:

The possibility of cumulative effect from visible laser radiation was investigated by two methods Testing for a change in the apparent ED50 after a series of previous subthreshold exposures histologically examining retinal tissue subjected to various series of subthreshold exposure. Neither method indicated a cumulative effect with a 30-sec interval between doses. Author
