Intraocular pressure was measured with a MacKay-Marg tonometer in eight horses following auriculopalpebral nerve block and topical application of lignocaine. Measurements were recorded before and after xylazine, 1.1 mg/kg intravenously, every two minutes for 16 minutes after administration of ketamine, 2.2 mg/kg intravenously, and after recovery from anaesthesia. Before xylazine, intraocular pressure was 17.1 +/- 3.9 and 18.4 +/- 2.2 mm Hg in the left and right eyes, respectively. Intraocular pressure tended to decrease after administration of xylazine and ketamine, with a significant decrease in one eye six minutes after injection of ketamine.
在八匹马身上，通过麦凯 - 马格眼压计测量了耳睑神经阻滞和局部应用利多卡因后的眼压。在静脉注射1.1毫克/千克甲苯噻嗪前和注射后，静脉注射2.2毫克/千克氯胺酮后每两分钟记录一次测量值，持续16分钟，并在麻醉恢复后记录。在注射甲苯噻嗪前，左眼和右眼的眼压分别为17.1±3.9毫米汞柱和18.4±2.2毫米汞柱。注射甲苯噻嗪和氯胺酮后眼压有下降趋势，在注射氯胺酮六分钟后一只眼睛眼压显著下降。
