病理过程可以在两个方面改变视网膜电图反应：反应时间和幅度（或标准阈值）。因此可以定义电生理综合征。在金属眼内异物的情况下，认识视网膜金属化对视网膜电图反应的影响具有临床重要性：敏感性降低，而刺激强度的反应时间保持正常。铁似乎比铜毒性更大，但铁诱导的继发纤维化比铜诱导的继发纤维化更有效地保护视网膜。
Electroretinographic responses can be modified by pathologic processes in two respects: response time and amplitude (or criterion threshold). Electrophysiologic syndromes can thus be defined. It is of clinical importance to recognize the effects of retinal metallosis on the electroretinographic response in cases of metallic intraocular foreign bodies: the sensitivity decreases while the response time remains normal for the intensity of stimulation. Iron appears to be more toxic than copper, but the secondary fibrosis induced by iron protects the retina more efficiently than that induced by copper.
