The 260 cases of acute hemorrhagic conjunctivitis seen at Siriraj Hospital during October to December, 1992 were studied. Evidence of coxsackie virus A24 variant (CA24v) infections was demonstrated in 76.8% of 95 cases. The isolation rates from conjunctival swabs and throat swabs were 68.2% and 32.8%, respectively. A four-fold rising titer of neutralizing antibody was shown in 59.5% of 42 cases. The disease was characterized by a short incubation period, sudden onset, a mild and self-limited course within 5 days without ocular sequelae. Lacrimation, swelling lida, itching, foreign body sensation and periorbital pain were common features with bilateral involvement in the majority of cases. Approximately 48% of eyes had a mucopurulent discharge. Preauricular lymphadenopathy, keratitis and subconjunctival hemorrhage were observed in 16.2%, 12.6%, and 10.1% of affected eyes, respectively. Respiratory disturbances accompanied the eye signs in some cases. Only one case developed neurological complications: facial palsy was observed for three months without recovery. |
