  • Title: [Retinal vasculopathy associated with Berger's IgA nephropathy].
    Author: Wolfensberger TJ, Piguet B, Gregor ZJ, Bird AC.
    Journal: Klin Monbl Augenheilkd; 2000 May; 216(5):334-8. PubMed ID: 10863709.
    Abstract:
    AIM: Ophthalmological complications associated with Berger's IgA nephropathy comprise scleritis, episcleritis, keratoconjunctivitis as well as anterior uveitis. We present a new association of IgA nephropathy with a retinal vasculopathy. METHODS: Presentation of two clinical cases. RESULTS: Two patients presented with hematuria and epistaxis associated with a retinal vasculopathy characterised by teleangiectasies, capillary occlusion with retinal hemorrhages, neovascularisations and macular edema with decreased visual acuity. Fluorescein angiography showed zones of non-perfusion as well as vasculitic changes. A general medical exam revealed a normal arterial pressure but a slightly elevated creatinine. Immunological investigations for the presence of antibodies showed no positive results. Renal biopsy demonstrated mesangial proliferations with diffuse deposits of IgA. Over the course of a 2 year follow-up some of the retinal changes regressed under treatment with cortisone and visual acuity returned to normal. The teleangiectasies showed no progression. CONCLUSION: Berger's IgA nephropathy can be associated with a retinal vasculopathy which may be due to local deposition of IgA immune complexes in the retinal vessels.
