title: Allergic granulomatous nodules of the eyelid and conjunctiva. The XXXV Edward Jackson Memorial Lecture.
abstract: We studied the clinical and pathologic features of 22 cases of granulomas of the conjunctiva or eyelids. All cases showed the histologic features of the Splendore-Hoeppli phenomenon, that is, a giant cell and eosinophil granulomatous reaction to an antigen-antibody precipitate originally described in relation to parasites or fungi. In four of seven typical cases selected for detailed description unidentified nematodes were found to be the cause of the condition. In light of these findings together with a review of similar "allergic granulomas" reported both in ocular tissues and elsewhere in the body, we considered the cause in the remaining cases. All 22 cases may have been caused by nematodes, as seems, probable in 14 of them, or the causative antigens may have been of widely different kinds. Although in our cases all ocular granulomas had an identical histology, this study did not resolve the problem of those cases where no causative agent was found. Thorough investigation of such cases in the future and the demonstration of their cause may elucidate the wider problem of nonocular allergic granulomas.
