[Uveitis and immune complexes].

The mean level of circulating immune complexes (CIC) in 24 uveitic patients determined by PEG deposition with the biochemical analyzor was found to be 28.458 +/- 7.796, in contrast to the value of 14.499 +/- 6.194 in the control group. The CIC level in acute iridocyclitis and panuveitis was significantly elevated compared with those in other types of uveitis. The results again demonstrated that most cases of uveitis, especially those of unknown origin, were related with immune complexes, and changes in the level of CIC could also be an indicator of therapeutic effects.
