A 22-year-old man presented with diminution of vision in the left eye 1 month after sustaining an injury from a high-voltage electric current to the left side of his head. Slitlamp examination and Scheimpflug imaging confirmed the typical anterior subcapsular lenticular opacities in the left eye and also documented early anterior subcapsular vacuoles in the right eye. Based on history, the electric shock wound, and the typical appearance of the opacities, an electric cataract was diagnosed. The difference in lens density between the 2 eyes was also documented. The best corrected visual acuity (BCVA) was 20/20 in the right eye and counting fingers at 1 foot in the left eye. Phacoaspiration and posterior chamber intraocular lens implantation were performed in the left eye. Postoperatively, the BCVA improved to 20/20. The developmental mechanisms of these opacities after exposure to an electric current and the role of Scheimpflug imaging in assessing the earliest subclinical manifestations of electric cataract injuries are discussed.
一名22岁男性在头部左侧遭受高压电流损伤1个月后出现左眼视力下降。裂隙灯检查和眼前节分析成像证实左眼有典型的前囊下晶状体混浊,同时也记录到右眼早期前囊下出现空泡。根据病史、电击伤情况以及混浊的典型表现,诊断为电击性白内障。还记录了两眼晶状体密度的差异。右眼最佳矫正视力(BCVA)为20/20,左眼仅能在1英尺处数指。对左眼进行了超声乳化吸除术和后房型人工晶状体植入术。术后,BCVA提高到了20/20。本文讨论了电流暴露后这些混浊的发生机制以及眼前节分析成像在评估电击性白内障损伤最早亚临床症状中的作用。
