One point low volume peribulbar anaesthesia versus retrobulbar anaesthesia. A prospective clinical trial.

A prospective trial was conducted on 142 patients who underwent cataract surgery, to compare the efficacy of a single point, low volume peribulbar with that of retrobulbar anaesthesia. It was found that peribulbar anaesthesia is as efficacious as retrobulbar anaesthesia without the associated complications. It also avoids the facial block used by most ophthalmologists to supplement a retrobulbar block, thus markedly reducing the post-operative patient discomfort as well as the total volume of anaesthetic used.
