A 59-year-old man with retinitis pigmentosa, who received an Argus II retinal prosthesis in the left eye 3 years prior, presented with left-sided involuntary facial contractions that occurred only after turning on the Argus II device.
A case report.
Given that this patient's reported and visualized lower eyelid twitching corresponds to the location of the external region of the implanted coil, we hypothesize that heat or wirelessly transmitted electrical signals from the external coil to the implanted coil may induce spasm of the facial nerve and thus play a role in hemifacial spasm onset.
To our knowledge, this is the first report of hemifacial spasm associated with Argus II use.
一名59岁的视网膜色素变性男性患者，3年前左眼植入了阿格斯II型视网膜假体，现出现仅在开启阿格斯II型设备后发生的左侧面部不自主收缩。
病例报告。
鉴于该患者报告的和可视化的下眼睑抽搐与植入线圈外部区域的位置相对应，我们推测来自外部线圈的热量或无线传输的电信号传输到植入线圈可能诱发面神经痉挛，从而在半面痉挛的发作中起作用。
据我们所知，这是首例与使用阿格斯II型相关的半面痉挛报告。
