The Effect of Colour Output of Intensifying Devices on Acuity in Pigmentary Retinal Degeneration

Abstract

Developments in phosphor technology have resulted in the possibility of producing intensifying devices with a variety of output colours. The present pilot study investigates the effect of phosphor colour on acuity performance in subjects suffering from pigmentary degeneration of the retina. The results of this study combined with previous data on dark adaptation and colour are used to provide recommendations regarding the most suitable intensifier output colour for such subjects.
