Background and Objectives. The peribulbar block is a safe and reliable alternative to the retrobulbar block. In this clinical report, we describe the anatomy of the orbit and the technique involved in performing the block.

Methods. The technique is not new, and modifications from the original paper by Mandel and Davis are few but significant. Complications include peribulbar hemorrhage, perforation of the globe and intravascular injection.

Results. In our experience of 2600 peribulbar blocks, we have seen five patients with minor peribulbar hemorrhage.

Conclusions. Supplementation of the block was required in 3% of the patients.
