Usefulness of Flow Cytometry in Diagnosis of IgG4-Related Ophthalmic Disease and Extranodal Marginal Zone B-Cell Lymphoma of the Ocular Adnexa

Background/Aim: Although flow cytometry (FCM) is used to evaluate cell surface markers of various leucocyte populations quantitatively, little is known about the usefulness of FCM in lymphoproliferative disorders of the ocular adnexa. The aim of this study was to disclose results of FCM, which were compared among IgG4-related ophthalmic disease (IgG4-ROD), idiopathic orbital inflammation (IOI), and extranodal marginal zone B-cell lymphoma...
