Abstract : The general objective of this program is to document changes in the retina due to very low laser irradiation. We have two primary aims. One is to develop and improve methods that can be used, in vivo, to objectively determine changes that occur in the retina from laser irradiation. The second is to determine the mechanisms that cause these retinal changes. During this past year we have: (1) Measured the change in retinal reflectivity during YAG and Argon Ion laser burn periods. (2) Determined the fluorescence decay time of fluorescein dye in water, blood and monkey retinas. (3) Obtained estimates of the amount of scattered light in the eye in the green and red spectral regions.
