Аннотация
PURPOSE: To report a case of uveitis in which unbiased metagenomic sequencing (MDS) and phage immunoprecipitation sequencing (PhIP-Seq) were performed on intraocular fluid.
OBSERVATIONS: A female patient with a past medical history of human immunodeficiency virus (HIV-1) who presented with chronic active anterior and intermediate uveitis with cystoid macular edema in the left eye. She had a previous ocular history of viral retinitis presumed to be secondary to cytomegalovirus (CMV). An anterior chamber tap was performed for viral polymerase chain reactions (PCRs), MDS, and pathogen PhIP-Seq. PCR testing and MDS were negative for pathogen genetic materials. PhIP-Seq detected antibody enrichment of CMV, as well as HIV-1 andSARS-CoV-2.
CONCLUSIONS: The combination of MDS and PhIP-Seq has the potential to provide additional insights into the pathogenesis and the ocular microenvironment of uveitis patients.
