目前对青光眼研究的关键问题之一是视神经对眼压升高的个体耐受性问题。作者指出,从正常人群中所得到的眼压正常值不能反应青光眼病人的眼压“正常值”。因为青光眼病人对眼压升高比正常人敏感,所以有不少病人在眼压“正常”中失明。由于眼压正常值的上界难以确定,所以许多学者为了确定眼对高眼压的个体敏感性作了研究。Lobstein(1966)曾以平均视网膜中央动脉压与眼压之差作指标,提出了所谓的Lobstein系数。(1977)以眼动脉的舒张压与眼压之差为指标,提出了所谓的“营养系数”。本文作者就眼对高眼压的个体敏感性问题,于1975年提出了一种确定个体耐受眼压的方法。
At present, one of the key problems in glaucoma research is the tolerance of the optic nerve to individuals with elevated intraocular pressure. The authors note that normal IOP values obtained from normal subjects do not reflect “normal” IOP in glaucoma patients. Because glaucoma patients with increased intraocular pressure than normal sensitivity, so many patients in the intraocular pressure “normal” blindness. As the upper bound of intraocular pressure is hard to determine, many scholars have studied the sensitivity of individuals to ocular hypertension. Lobstein (1966) once averaged the difference between the central retinal artery pressure and intraocular pressure as an indicator of the so-called Lobstein coefficient. (1977) to the difference between diastolic blood pressure and intraocular pressure of the eye artery as an indicator, the so-called “nutrition coefficient.” In this article, the author put forward a method to determine the intraocular pressure of an individual with respect to the individual sensitivity to ocular hypertension.
