Molecular diagnosis of acute retinal necrosis secondary to cytomegalovirus in vitreous aspirate.

ABSTRACT

We report a case of a 45-year old Filipino post-kidney transplant patient maintained on steroids, who presented with floaters in her left eye. Vitreous aspirate was analyzed using polymerase chain reaction (PCR) for human cytomegalovirus (HCMV) and herpes simplex virus (HSV). A distinct band (435 bp) was found that confirmed the presence of HCMV. Since a rapid and accurate diagnosis is crucial for prompt administration of antiviral therapy, PCR-based analysis of vitreous aspirate provides a valuable tool in the diagnosis of patients with retinitis caused by herpes viruses.
