description: "Change in the color of the fundus from red in the dark-adapted state to golden immediately or shortly after the onset of the light. The color of the fundus reflex in the light adapted state has also been described as golden-yellow, gray-white, and yellow-white. This reflex can appear either homogeneous or in streaks in the fundus. The retinal vessels appear to be protruding in contrast to the radiant background. Dark adaptation leads to disappearance of the unusual fundus coloration [Digital Journal of Ophthalmology 2008; Volume 14, Number 14]."
