Fig. 4From: Comparison of Ex-PRESS implantation versus trabeculectomy combined with phacoemulsification in primary open-angle glaucoma: a retrospective in vivo confocal microscopy studyGiemsa stain of hyperreflective dot. In vivo confocal microscopy (IVCM) and corresponding Giemsa stain of two different patients are shown. In a and c, the patient whose IVCM showed numerous hyperreflective dots (blue arrows) in the conjunctiva also showed numerous neutrophil- and monocyte-like inflammatory cells (red arrows) in a scrape sample of conjunctiva over filtering bleb. In b and d, the patient showed no hyperreflective dots in the IVCM and likewise saw no appearance of inflammatory cells but only fragments of cells (black arrows) from the scrape sampleBack to article page
