ABSTRACT
This study aimed to examined the influence of adrenaline in retrobulbar anesthesia on examined the influence of adrenaline in retrobulbar anesthesia on the preoperative IOP and on position of the lens-iris diaphragm during extracapsular cataract extraction [ECCE]. The effect of adrenaline on akinesia, analgesia and the frequency of complications was also studied. 74 patients with cataract underwent a planned ECCE. They were randomly divided into 2 groups: Group I receiving retrobulbar anesthesia with adrenaline and group II without adrenaline. The results revealed that group I had the lowest mean IOP after the retrobulbar injection [P <0.05]. They required shorter time of digital bulbar massage to reduce tension before surgery [P <0.01], they also appeared to have a deeper anterior chamber during the 1st part of surgery. The duration of postoperative analgesia was significantly prolonged in patients receiving adrenaline. The use of adrenaline as an adjunct to the retrobulbar anesthetic solution is beneficial in ECCE
