The use of intra-oral local anaesthetics for dental procedures is a widely extended practice that may cause side effects. As such, in rare cases it may cause ocular complications such as diplopia, ptosis, blurry vision, miosis, vision loss, or amaurosis. (Most of them are transient, recovering after several hours or days). A case is presented of a 26 year-old male patient who had visual impairment in the right eye 2 days after a dental procedure was performed. Six months later he had a complete restoration of the previous visual acuity, despite the fact that he had not received any treatment. Several ways have been proposed in the literature that may explain the appearance of ocular complications following these kinds of procedures. In this case, inadvertent intravenous injection is believed to have been the cause.
口腔内局部麻醉剂在牙科手术中的应用是一种广泛应用的做法，但可能会引起副作用。因此，在极少数情况下，它可能会引起眼部并发症，如复视、上睑下垂、视力模糊、瞳孔缩小、视力丧失或失明。（大多数是短暂的，在数小时或数天后恢复）。本文介绍了一例 26 岁男性患者，在牙科手术后 2 天出现右眼视力障碍。6 个月后，他的视力完全恢复到以前的水平，尽管他没有接受任何治疗。文献中提出了几种可能解释这类手术后出现眼部并发症的原因。在这种情况下，据信是意外的静脉内注射导致了这种情况。
