Using immunohistochemical techniques, we analyzed iris biopsy specimens from eight patients with Fuchs' heterochromic cyclitis, seven patients with various other types of uveitis, and eight glaucoma patients without uveitis. No specific abnormalities related to Fuchs' heterochromic cyclitis could be detected. Four of the patients with Fuchs' heterochromic cyclitis and four of the patients with uveitis showed evidence of an inflammatory cell infiltrate, which was a mixture of interleukin-2 receptor-negative T helper and suppressor cells, B lymphocytes, and plasma cells. Only an occasional T lymphocyte could be seen in two of the patients without uveitis. The class II antigen HLA-DR was expressed on iris stromal cells in every patient in the Fuchs' heterochromic cyclitis group and uveitis group and in six of the patients in the nonuveitis group. In six of the Fuchs' heterochromic cyclitis patients, including two without immunohistochemical evidence of inflammatory cell infiltrate, histologic abnormalities were present on hematoxylin and eosin sections.
