Visual Loss After Intraoral Local Anesthesia for the Removal of Circumzygomatic and Circum-Mandibular Wires: A Case Report.

Many types of complications occur after intraoral local anesthesia; however, visual loss is a rare one. There have been only a few case reports of visual disturbance after intraoral local anesthesia. A 67-year-old man with systemic hypertension complained of visual disturbance after a dental local injection for circumzygomatic and circum-mandibular wire removal. Forty-nine days later, he had partly recovered his vision. To date, the exact mechanism of visual loss after dental injection remains unclear. This rare case could provide another clue to the etiology and caution against similar complications.
