| الوصف: |
In order to understand battlefield hazards of laser exposure under field conditions, it has been necessary to evaluate effects of small punctate foveal lesions on visual function on non-human primates. Previous experiments have found correlation between functional loss and foveal damage. The present investigation showed that detecting the effects of small foveal lesions - those that might be produced under field conditions - is not an easy task. From the results of this investigation, we forsee the possibility that considerable foveal damage could occur before a measurable change in visual function could be detected with presently available visual function testing procedures. We recommend more sensitive visual function test procedures, such as clinical tests that measure both spectral and spatial resolution under threshold contrast conditions. |
