Implication

Diagnostic study demonstrates variable PCR pathogen detection across ocular fluids in patients with infectious uveitis, highlighting PCR as a supportive rather than standalone diagnostic tool.

Key Points

To evaluate the sensitivity and specificity of polymerase chain reaction testing of serum, aqueous humor, and vitreous humor for identifying infectious pathogens in patients with presumed infectious uveitis.
Evaluated 20 patients presenting with presumed infectious uveitis (16 with AIDS and 4 immunocompetent) alongside 4 uninfected controls undergoing vitrectomy.
Conducted joint clinical evaluations by three ophthalmologists and performed masked PCR analysis of serum, aqueous humor, and vitreous humor samples for CMV, HSV, VZV, EBV, Mycobacterium sp., and Toxoplasma gondii.
Vitreous PCR detected pathogens in 50% (6/12) of CMV retinitis cases and 60% (3/5) of acute retinal necrosis cases, with serum PCR positive in 25% (3/12) of CMV cases.
Aqueous humor PCR was positive in 75% (3/4) of ocular toxoplasmosis cases compared to 50% (2/4) in vitreous and 25% (1/4) in serum.
One presumed ocular tuberculosis case tested positive in both serum and vitreous PCR, whereas 0% (0/4) of control participants demonstrated positive PCR results across all fluids.
