  • Look Inside

We tested intraocular fluids in 23 cases of acute retinal necrosis regarding viral antibody titer and polymerase chain reaction (PCR). Aqueous humor was obtained in 22 samples and vitreous aspirate in 17. Aqueous sample obtained during the early phase of the disease showed positive PCR identification of the causative virus but unremarkable viral antibody ratio. Vitreous samples showed similar results in the incidence of positive PCR results and viral antibody ratio regardless the timing of sampling. As an overall finding, samples taken before 20 days after onset of disease showed higher rates of positive PCR findings. Samples taken thereafter showed higher incidence of viral antibody titer. The findings show that PCR studies are indicated for the early stage of the disease and that viral antibody studies are more sensitive for later stages.
