Abstract

Cytomegalovirus (CMV) can cause recalcitrant recurrent keratouveitis and secondary glaucoma. We report a case of chronic recurrent anterior uveitis with secondary glaucoma presenting with acute visual loss and interface fluid 9 years after laser in situ keratomileusis. Based on clinical presentation, a viral aetiology was suspected. Aqueous tap was positive for CMV-DNA by real-time quantitative PCR of the aqueous humour. The patient was treated with systemic antivirals, topical corticosteroids and antiglaucoma medications. The interface fluid resorbed rapidly. The intraocular pressure (IOP) was controlled by trabeculectomy. There was no further corneal deterioration at 7-month follow-up and the IOP had also stabilised. We believe this is only the third reported case of CMV-related interface fluid syndrome. This case highlights the role of quantitative PCR analysis for establishing viral aetiology in recurrent unilateral hypertensive anterior uveitis and reports the unusual finding of interface fluid which resolved after starting systemic antiviral therapy.
