白内障手术前压迫眼球已作为常规降压措施应用于临床。本研究旨在探讨老年性白内障患者眼压有何个体差异、不同个体对压迫降压的反应如何。我们对连续90例患者,采用自制的不锈钢压迫器持续压迫双眼15分钟,用 Schitz 氏眼压计测量压迫前后眼压。结果表明,老年性白内障患者,女性眼压较男性为高, (t 检验 P<0.01);左眼眼压的平均数高于右眼,随着体重指数的上升,眼压平均数略有上升,(F 检验 P>0.05)。压迫器对眼球持续压迫15分钟,无论男女及体重指数如何,压迫后较压迫前眼压均明显降低,下降幅度达0.59～0.75kPa(t 检验 P<0.01)。
Compression of the eye before cataract surgery has been used as a routine antihypertensive measures in clinical. The aim of this study was to investigate the individual differences in intraocular pressure (IOP) among senile cataract patients and how different individuals respond to oppression and depression. For 90 consecutive patients, we continued to compress the eyes for 15 minutes with a self-made stainless steel compression device and measured the intraocular pressure before and after compression using a Schitz’s tonometer. The results showed that the IOP was higher in women than in men (t-test, P <0.01). The average IOP in the left eye was higher than that in the right eye. The mean IOP increased slightly with the increase of body mass index , (F test P> 0.05). Oppressor continued oppression of the eye for 15 minutes, regardless of men and women and body mass index, after oppression than before oppression were significantly lower intraocular pressure, a decrease of 0.59 ~ 0.75kPa (t test P <0.01).
