Abstract:
In order to compare the influence of retrobulbar and peribulbar anesthesia technique to the change of intraocular pressure(IOP), we measured the IOP sequentially in 40 eyes of 40 patients(retrobulbar group: 20 eyes, peribulbar group: 20 eyes). The intraocular pressure was checked at one hour prior to operation, just after application of Honan apparatus with 30 mmHg for 30 minutes, just after the injcetion of anesthetics with technique retrobulbar and with peribulbar technique, and after digital massage for 5 minutes. Injected volume of anesthetics was 3 ml in retrobulbar technique and 6 ml in peribulbar technique. In retrobular group, the IOP mean was 16.55 mmHg at one hour prior to operation, 10.96 mmHg just after Honan application, 17.36 mmHg just after the injection of anesthetics and 10.38 mmHg after digital massage. In peribulbar group, the IOP mean was 16.97 mmHg at one hour prior to operation, 11.08 mmHg just after Honan application, 18.11 mmHg just after the injection of anesthetics and 11.31 mmHg after digital massage. The mean increase of IOP after the injection of anesthetics was 6.40 mmHg in retrobulbar group and 7.03 mmHg in peribulbar group. There was no statistical difference in the change of IOP between the two groups.(Student t-test, p>0.10).
