The involvement of the retina in the inflammation being one important factor in severe uveitis, the authors have tested the "ganzfeld" electroretinogram (ERG) in various forms of uveitis, especially in cases having opaque media. In Fuchs' syndrome and chronic anterior uveitis, the ERG is normal or only slightly altered, while important reduction of the potentials can occur even in case of good vision in intermediate uveitis, probably indicating concomitant retinal vasculitis. In Behçet's disease, ERG is mostly useful in testing the efficacy of therapy. ERG can be rather deceiving in idiopathic vasculitis, where the potentials are not always as reduced as expected. On the contrary, this test seems to allow differential diagnosis between Harada's disease and acute multifocal placoid pigment epitheliopathy. However, one must bear in mind that concurrent steroid treatment can elevate the amplitude of the potentials, a phenomenon which has to be taken into account when interpreting ERG results.
视网膜参与炎症是严重葡萄膜炎的一个重要因素，作者在各种形式的葡萄膜炎中，特别是在有不透明介质的病例中，测试了“全视野”视网膜电图（ERG）。在富克斯综合征和慢性前葡萄膜炎中，ERG正常或仅略有改变，而在中间葡萄膜炎中，即使视力良好，电位也可能出现显著降低，这可能表明伴有视网膜血管炎。在白塞病中，ERG主要用于测试治疗效果。在特发性血管炎中，ERG可能会产生误导，因为电位并不总是像预期的那样降低。相反，这项检查似乎有助于鉴别原田病和急性多灶性扁平色素上皮病变。然而，必须记住，同时进行的类固醇治疗可提高电位幅度，在解释ERG结果时必须考虑到这一现象。
