A severe form of unilateral uveitis, which in most cases leads to blindness within hours of its onset, has been seen in Nepal since 1975. This disease appears with the onset of autumn in early September and lasts until the end of December in two-year cycles (1975, 1977, 1979). However, some cases occurred in 1980 as well. ⋯ Some of these were claimed to be followed by blister formation at the point of contact. These moths were presumed to be responsible for producing this uveitis in those cases. The present report describes the clinical features of the cases seen from the time the disease was first recognized, case histories of four cases seen during the last outbreak, results of laboratory experiments using the aqueous humor of these patients, and the results of experiments using three different varieties of moths.
