Abstract
Purposes:
A case of gonococcal keratoconjunctivitis rapidly diagnosed by a vaginal swab PCR Xpert® CT/NG assay.
Methods:
Case report.
Results:
A 26-year-old woman presented to our emergency department with severe perilimbal stromal melting in both eyes and profuse purulent discharge for one day. Upon emergent ocular consultation, gonococcal keratoconjunctivitis was suspected. A vaginal swab was sent for rapid PCR Xpert® CT/NG assay which reported positive Neisseria gonorrhoeae (NG) and Chlamydia Trachoma (CT) DNA detection within 90 min. Due to the rapid diagnosis, adequate medical intervention with ceftriaxone injection was administered. Gonococcal keratitis with stromal melting was stabilized within 5 days of presentation. The patient was discharged with complete epithelial healing by the 8th day. However, 10 weeks after discharge, inadvertent rubbing of the left eye resulted in corneal perforation with iris prolapse. Lamellar keratoplasty with corneal patch graft was performed with amniotic membrane grafting. Xpert® CT/NG assay was performed again with conjunctival swab for recurring mild eye discharge. Both NG and CT were negative. The patient thus stabilized with no further complications.
Conclusions:
Rapid stromal melting can occur with un-diagnosed or delayed diagnosis of gonorrhea with ocular involvement. Speedy and accurate diagnosis by the highly sensitive and specific Xpert® CT/NG assay can provide early definite diagnosis for prompt treatment in prevention of gonococcal infection induced corneal perforations.
