The interphotoreceptor matrix of the human retina was examined histochemically by staining with a cationic copper phthalocyanin dye, Cuprolinic Blue, in a critical electrolyte concentration method which allowed staining of sulfated polyanions. In the presence of Cuprolinic Blue, a dense punctate matrix component was visualized covering the cone from the… CONTINUE READING
