Aqueous tap and rapid diagnosis of cytomegalovirus anterior uveitis: the Reggio Emilia experience

Purpose The diagnosis of cytomegalovirus (CMV) anterior uveitis in immunocompetent patients requires confirmation by polymerase chain reaction (PCR) analysis and/or intraocular antibody index (AI) assay. In this study, we analyzed the different contributions of PCR and AI to CMV diagnosis by performing one single aqueous tap.
