Transient loss of power of accommodation in 1 eye following inferior alveolar nerve block: report of 2 cases

Unintended intravascular injection from inferior alveolar nerve blocks can result in frustrating distant complications affecting such structures as the middle ear and eyes. Possible complications affecting the eyes include blurring of vision, diplopia, mydriasis, palpebral ptosis and amaurosis ( tem...
