INJURIES INDUCED BY DIFFUSE PHOTODYNAMIC ACTION IN RETINA AND CHOROID OF ALBINO RATS

Abstract

Damage produced by this model was irregular in extent and character, due to several hard-to-control parameters. It was presumably due not only to ischemia but also to free radical chain reactions initiated by photodynamic action. This model may not be suitable for rapid quantitative assessment of ischemic retinal injury, but it provides opportunities for the investigation of pathophysiologic mechanisms.
