Because retrobulbar blocks do not provide lid akinesia, they are often combined with van Lint blocks. This method of facial nerve block was the first to be reported and is considered to be the classic technique. Typically, 5 to 10 mL of anesthetic (often the same mixture as used for the retrobulbar block) is used, although some suggest that volumes as low as 2 mL are sufficient.
