We performed fluorescein angiography using a scanning laser ophthalmoscope (SLO) in 32 eyes with idiopathic macular holes in stages 1B, 2, 3, and 4 before and after successful vitreous surgery. The fundus was also observed by SLO using helium-neon and argon blue lasers as light sources. Before surgery, fluorescein angiography showed intense hyperfluorescence in the floor of macular hole surrounded by faint petalloid hyperfluorescence. This petalloid pattern corresponded to the radiating folds of elevated Henle's fiber as were shown by SLO using helium-neon laser. The operculum appeared dark and blocked the fluorescence from the floor of the hole. These features suggested that the dark macula as observed by fluorescein angiography in normal eyes originates from the xanthophyll in the neurosensory retina and that its absence is responsible for the hyperfluorescence in the hole area. After successful surgery, dark macula was restored in varying degrees. The tissue, which sealed the macular hole, is supposed to contain xantho-phyll.
