Visual functional changes associated with low-level light effects.
Development of more sensitive human clinical visual function tests is required for early detection of both acute and chronic laser exposure effects. Detection of low-level laser light exposure depends upon the measure of visual function employed. Visual function measures may reflect physiological processes at the retina as well as those at higher visual cortical centers. This paper focuses on the complexity of these measures through review of various experimental investigations using a variety of different measures to correlate retinal and functional alteration.
