Intra-ocular pressure during retrobulbar injection.
It was found that the use of retrobulbar injections can cause quite large transient rises in intra-ocular pressure which can be significantly reduced by using local anaesthetic in the injected saline, and by injecting in small steps, typically 0.2 to 0.3 mls/kg body weight at 1 minute intervals for a total of not more than ten steps. After a moderate retrobulbar injection, the intra-ocular pressure was found to return to near normal in a few minutes, but with some decrease in anterior chamber volume.
