RESUMO
Objective To explore the changes and significance of the circulating immunocomplexes(CIC) in patients with chronic iridocyclitis.Methods We assessed circulating immunocomplexes in peripheral blood of 45 patients with recurrent uveitis and 42 healthy controls by PEG deposition with the biochemical analyzer to obtain levels of CIC different with recurrent uveitis.Results Levels of CIC were significantly higher in active patients(27.358±6.729)than those in controls(13.459±6.164,P＜0.001) and inactive patients (16.248±6.233,P＜0.001),but patients (inactive) had significantly higher levels than those in controls (P＜0.05).Conclusion Levels of CIC were found in the groups of active patients with recurrent uveitis (27.358±6.729), but levels of CIC in inactive patients fell. The result of this study suggest that recurrence of uveitis is related to immunocomplexes,and changes in the levels of CIC could be also a measure standard of therapeutic effects.
