The pathogenesis of the fundus peau d'orange and salmon spots.

The fundus of the eye of a patient with pseudoxanthoma elasticum showed angioid streaks, fundus peau d'orange and salmon spots, these latter unusually located in the macula. The fluorescein angiography revealed, in the arterial phase, a reticular hyperfluorescence in the areas of fundus peau d'orange and salmon spots. In the venous phase the fluorescence of the fundus peau d'orange was even, while the salmon spots showed staining and hyperfluorescent borders. These findings support the hypothesis that the fundus peau d'orange is due to degeneration of Bruch's membrane and the salmon spots are deiscences of this membrane.
