Figure 1.
Frequency of regional (peribulbar or retrobulbar block) with monitored anesthesia care versus general anesthesia use by zone of injury from 2004 to 2014. Regional anesthesia was preferential anesthesia type in Zone 1 injury (88% vs 12%) and Zone 2 injury (77% vs 23%) but both anesthesia types (regional and general anesthesia) were used equally in Zone 3 injury (47% vs 53%).
