Post-streptococcal uveitis.

Background: We report additional evidence supporting the association between the occurrence of bilateral nongranulomatous uveitis and previous infection by group A streptococci--i.e., post-streptococcal syndrome.
Methods: As shown through a series of case reports, physical examination and laboratory blood analysis--including antistreptolysin O (ASO) antibody titer--were ordered due to a recent history of sore throat and presence of nongranulomatous bilateral anterior uveitis.
Results: Serological laboratory testing revealed elevated ASO antibody titer. The etiology of the uveitis was attributed to streptococcal infection. Bilateral uveitis responded to topical corticosteroids. Systemic antibiotic treatment was used to treat possible post-streptococcal syndrome sequelae with resolution of symptoms.
Conclusion: Uveitis should be considered a possible manifestation of post-streptococcal syndrome. ASO antibody quantification should be included in the serologic testing performed in evaluating the cause of seemingly idiopathic bilateral nongranulomatous anterior uveitis associated with signs and symptoms that suggest previous streptococcal infection.
