Herpes Simplex Virus Anterior Uveitis in a Child Presenting as a Hypopyon in a White Eye

ABSTRACT Purpose To report a rare ocular presentation of unilateral anterior uveitis with hypopyon in a 5-year-old child, suspected as masquerade. Methods Retrospective report Results A 5-year-old boy presented with hypopyon-uveitis. Detailed systemic work-up was negative for masquerade and uveitis entities. He was started on oral and topical steroids but had reactivation on taper. Real-time polymerase chain reaction (PCR) test of aqueous fluid was positive for herpes simplex virus (HSV)-1 DNA. The inflammation resolved completely on oral acyclovir and topical corticosteroids. He subsequently underwent pars plana lensectomy, primary posterior capsulotomy and vitrectomy for complicated cataract. Post-operatively, vision improved to 20/400 with aphakic correction. Maintenance oral acyclovir was stopped after 3 months with no reactivation and amblyopia therapy was continued. Conclusion This is a rare presentation of hypopyon uveitis due to HSV-1 in a child. The role of real-time PCR in establishing the diagnosis is crucial in such cases of diagnostic dilemma.
