Tear fluid lysozyme concentration: guide to practolol toxicity.

Heerfordt's syndrome is an unusual manifestation of sarcoidosis consisting of parotitis with chronic or subacute uveitis and often complicated by cranial nerve pareses, usually of the facial nerve. Originally described in 1909,1 it was not recognised as a manifestation of sarcoidosis until 1937. The complete picture is rare. Scadding2 had no cases of the complete syndrome in his series, and Greenberg et al,3 reviewing 388 cases of sarcoidosis, reported only 8 with uveoparotitis and only one with a facial palsy. Familial association in sarcoidosis is well recognised.4 In 13 instances of sarcoidosis affecting identical twins the manifestations of the disease in each twin pair tended to be similar.5 This seems to be true of less closely related subjects. Interestingly, both our cases presented almost simultaneously with a most uncommon form of sarcoidosis and followed very similar courses.
