Comment on papers by Ashikari, Ozeki, Tomida, Sakurai, Tamai, Ogura: retention of dye after indocyanine-green assisted internal limiting membrane peeling, and by Ciardella, Schiff, Barile, Vidne, Sparrow, Langton, Chang: persistent indocyanine green fluorescence after vitrectomy for macular hole

In this regard Case 2 presented by Ashikari and colleagues appears very interesting, as ICG traces can be seen within retinal cysts. Since the cysts are usually located between the outer plexiform layer and the inner nuclear layer, Ashikari and colleagues observed persistent intraretinal staining.
