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 causes these retinal changes. During this past year we have Modified our equipment to do small retinal area reflectivity, measurements Measured the internal light scatter in the eye for wavelengths from 450 to 850 mm Measured many fluorescence parameters after a single injection of fluorescence Accurate measurements of spectral reflectivities of small areas of a laser damaged monkey retina and they have been proven to be feasible Perfected a photographic technique to improve the resolution and contrast of fluorescence angiograms and Recommended several dyes for use as dyed tear films for retinal protection from laser radiation.
