Follow-up studies on 113 patients with various types of primary glomerular diseases were performed for one to 33 months to determine the clinical spectrum of primary glomerulonephritis. Of those studied, six patients exhibited scleritis. All of these six patients with scleritis were identified as having "IgA nephropathy." None of the patients other than those with IgA nephropathy showed scleritis during the study period. It is suggested that some autoimmune mechanisms similar to the manifestation of IgA nephropathy may be involved in the development of scleritis.
