目的报告1例白内障术后20个月晶状体碎片诱发葡萄膜炎并伴有异常闪光视网膜电信号(ERG)的病例。方法这是一份观察性病例报告。用RETval系统记录全场闪光ERG。随访期间采用光学相干断层扫描(OCT)和裂隙灯生物显微镜对葡萄膜炎进行评估。结果1例70岁男性，20个月前接受白内障手术，主诉右眼视力下降。裂隙灯生物显微镜下可见角膜水肿，前房下部可见晶状体碎片。OCT显示黄斑囊样水肿，闪光ERG显示右眼波幅明显增加，潜伏期延长。在摘除晶状体碎片和应用局部抗炎药物后，闪光ERG的这些异常逐渐改善。结论本病例为晶状体诱导性葡萄膜炎，其闪光ERG波幅异常。临床医生应该意识到，患有葡萄膜炎的眼睛可能会有比正常眼更大的ERG振幅。
Purpose To report our findings in a case of lens fragment-induced uveitis associated with supernormal flicker electroretinograms (ERGs) twenty months after the cataract surgery. Methods This is an observational case report. Full-field flicker ERGs were recorded with the RETevalsystem. Optical coherence tomography (OCT) and slit-lamp biomicroscopy were used to assess the uveitis during the follow-up period. Results A 70-year-old man, who had undergone cataract surgery 20 months earlier, visited our hospital with a complaint of decreased vision in his right eye. Slit-lamp biomicroscopy revealed corneal edema and a lens fragment was detected in the inferior part of the anterior chamber. OCT showed cystoid macular edema, and flicker ERGs showed a marked increase in the amplitude and a delay in the implicit time in the right eye. These abnormalities of the flicker ERGs improved gradually after the removal of lens fragment and application of topical anti-inflammatory medications. Conclusion Our case of lens-induced uveitis had supernormal flicker ERG amplitudes. Clinicians should be aware that eyes with uveitis can have larger-than-normal ERG amplitudes.
