Functional Assessment of High Level Laser Irradiation.

Abstract

High energy, Q-switched pulses from a laser are known to produce punctate lesions on the retina. The structural alterations often extend well beyond the primary area of exposure. In this report we have examined the changes in visual sensitivity following single pulses of 532 nm light several orders of magnitude above the ED 50 level. Both temporary and long term changes in spectral acuity and contrast sensitivity indicate the functional consequences of intense laser irradiation of minute areas of the central fovea. Keywords: Visual acuity loss; Neodymium: YAG lasers; Laser hazards; Rhesus monkey; Minimal laser spot; Exposure (Physiology)
