Abstract:
Inferior Alveolar Nerve Block (IANB) anaesthesia is one of the common procedures in dental clinic. This procedure is safe, but complications may still occur. Ocular complications such as diplopia, loss of vision, or ophthalmoplegia are extremely rare. This case report explains an event where due to individual anatomic variation of the sympathetic vasoconstrictor nerve and maxillary and middle meningeal arteries, intravascular administration of anaesthetic agent caused unusual ocular signs and symptoms such as temporary blindness.
