Posterior peribulbar anaesthesia for intra-ocular surgery.

Posterior peribulbar anaesthesia is a safe alternative to the better-known retrobulbar route because the local anaesthetic agent is deposited outside the ocular muscle cone and away from the retrobulbar nerves and blood vessels. The potential dangers of a retrobulbar injection are therefore greatly reduced but the same degree of anaesthesia and akinesia is achieved. The much safer and easier posterior peribulbar technique for intra-ocular surgery is described with reference to more than 400 cases.
