PURPOSE
To describe a visually evoked potential (VEP) examination performed on a patient with a keratoprosthesis.
METHODS
We report the case of a 60-year-old patient with a Fyodorov-Zuev keratoprosthesis in the right eye complained of gradual visual deterioration in that eye. His past medical history consisted of failed corneal graft procedures due to corneal dystrophy and an Ahmed valve implantation due to secondary glaucoma. A clinical examination and an ultrasound demonstrated vitreal opacities. In order to assess the visual status, a flash VEP test was conducted.
RESULTS
VEP recorded from the right eye consisted of a broadened and poorly formed positive P1 wave, with a subnormal amplitude, but a normal latency. Consequently, the patient underwent a pars plana vitrectomy.
CONCLUSION
This case demonstrates the viability of VEP exams in patients with keratoprostheses.
目的
描述对一名角膜移植患者进行的视觉诱发电位（VEP）检查。
方法
我们报告了一名60岁患者的病例，该患者右眼植入了费奥多罗夫-祖耶夫角膜移植片，主诉该眼视力逐渐下降。他过去的病史包括因角膜营养不良导致角膜移植手术失败，以及因继发性青光眼植入艾哈迈德瓣膜。临床检查和超声显示玻璃体混浊。为了评估视觉状态，进行了闪光VEP测试。
结果
右眼记录的VEP包括一个变宽且波形不佳的正向P1波，振幅低于正常，但潜伏期正常。因此，该患者接受了玻璃体切除术。
结论
本病例证明了VEP检查在角膜移植患者中的可行性。
