Definition: Millimeter mercury
The torr (symbol: Torr) or millimetre of mercury (mmHg) is a non-SI unit of pressure. It is the atmospheric pressure that supports a column of mercury 1 millimetre high. The unit is named after Evangelista Torricelli, Italian physicist and mathematician, for his discovery of the principle of the barometer in 1643.

Definition: Kilopascal
The SI prefix "kilo" represents a factor of
103, or in exponential notation, 1E3.
So 1 kilopascal = 103 pascals.
The definition of a pascal is as follows:
The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.

人工晶体植入术后继发性青光眼的手术时机
【摘要】 目的探讨人工晶体植入术后继发性青光眼(implantation secondary glaucoma,IOL)的手术时机。方法收集自2010年12月--2015年12月收治的22例人工晶体植入术后IOL患者,根据手术时机选择的不同将22例患者(22眼)分为观察组(n=12)和对照组(n=10),观察组患者在眼内压30~50 mm Hg(1 mm Hg=0.133 k Pa),药物治疗无效3~5 d时的难治性青光眼行小梁联合虹膜根切术进行治疗,对照组患者在眼内压超过50 mm Hg,药物治疗无效超过7 d的难治性青光眼再行上述手术治疗,随访并记录两组患者术后1周、1个月、3个月的眼内压,并行统计学对比。结果两组患者手术过程均顺利,观察组患者术后1周眼内压(18.2±9.0)mm Hg,1个月眼内压(14.3±8.2)mm Hg,3个月眼内压(15.7±8.9)mm Hg,与对照组相比,术后1周、1个月眼内压,差异存在统计学意义(均P&0.05);术后3个月两组患者平均眼内压较为接近,差异无统计学意义(P&0.05)。结论小梁联合虹膜根切术是治疗人工晶体植入术后IOL的有效术式,在其发病早期,眼内压30~50 mm Hg时行此手术治疗,能缩短眼内压恢复正常的时间,改善患者预后,提高生活质量,值得临床推广应用。
