Abstract
An English Electric Valve Co. P8073 light intensifier was set up with a viewing system to assess the performance of retinitis pigmentosa sufferers at low luminance levels. Six subjects had their acuity measured at different luminance levels using a light intensifier initially and subsequently using direct vision. All subjects showed an improvement in acuity using the intensifier compared with direct vision at levels of illumination ranging from 0.25 cd m-2 to 20 cd m-2.
