摘要

目的。本研究采用眼反应分析仪(ORA)对健康眼和青光眼纤维膜的“刚性”和“波动”标准进行分类,并根据WHO的分类方法,在考虑年龄的情况下,确定健康眼和青光眼纤维膜的“刚性”和“波动”标准的可能平均值范围,并确定与这些范围相对应的适当的真眼压(IOP)区。本研究采用Koshitsa-Svetlova动态诊断法,对青光眼纤维膜硬度和波动的临床测量值、当前真IOP水平和青年个体IOP水平进行理论分析,共纳入674只健康青光眼和518只年龄在18 ~ 90岁之间的青光眼,按年龄阶段按who标准进行分布。健康眼睛和青光眼的硬度和波动平均值的"阶梯模式"分布按"阶梯模式"分布,这使得可以根据这些阶梯对眼压区进行适当的排序,同时考虑到卫生组织规定的年龄阶段。确定了健康眼和青光眼的适当IOP水平范围:低IOP区(高达13 mm Hg);中等眼压区(14-20 mm Hg);眼压升高区(21 ~ 26 mm Hg);高眼压区(27 ~ 32 mm Hg);IOP亚补偿区(33 - 39mmhg)和未补偿IOP区(≥40mmhg)。刚性、波动的平均值的“台阶”和足以满足它们的IOP范围不相交。纤维膜硬度的当前值和年轻时计算的IOP值可以可靠地将每只健康或青光眼的眼睛归为其单独的IOP区。纤维膜的硬度一致决定IOP的水平(p>0.001),而巩膜的硬度和波动直接影响其当前水平。基本标准-眼纤维膜的刚性和波动-不依赖于角膜中央厚度,客观地决定了纤维膜的当前功能状态。客观可靠地确定健康眼睛或青光眼是否属于其单独的IOP区,对于综合诊所网络尤为重要。这种快速诊断的时间为0.02秒。

On adequate zones of true intraocular pressure in healthy and glaucoma eyes
PURPOSE. The study was conducted to reveal using the Ocular Response Analyzer (ORA) the possible ranges of mean values of the “rigidity” and “fluctuation” criteria for fibrous membrane of healthy and glaucoma eyes with consideration of the age periods according to the classification by WHO, and to identify adequate true intraocular pressure (IOP) zones corresponding to these ranges.METHODS. The study consisted of a theoretical analysis of clinical measurements of rigidity and fluctuation of the fibrous membrane, the current level of true IOP and the individual level of IOP calculated in youth using ORA by the method of dynamic diagnosis of Koshitsa-Svetlova, and involved in total 674 healthy and 518 glaucoma eyes from individuals aged 18 to 90 years, who were distributed by age periods according to WHO.RESULTS. A "step pattern" of the distribution of Average values of rigidity and fluctuation in healthy and glaucoma eyes were distributed in a “step pattern”, which made it possible to rank the IOP zones adequately to these steps, taking into account the age periods according to WHO. The following adequate ranges of IOP levels for healthy and glaucoma eyes were identified: low IOP zone (up to 13 mm Hg); medium IOP zone (14–20 mm Hg); elevated IOP zone (21–26 mm Hg); high IOP zone (27–32 mm Hg); IOP subcompensation zone (33–39 mm Hg) and uncompensated IOP zone (≥40 mm Hg). The "steps" of the average values of rigidity, fluctuations, and the IOP ranges adequate to them do not intersect. The current value of the rigidity of the fibrous membrane and the IOP value calculated in youth make it possible to reliably attribute each healthy or glaucoma eye to its individual IOP zone.CONCLUSION. Rigidity of the fibrous membrane consistently determines the level of IOP (p>0.001), while the rigidity and fluctuation of the sclera directly influence its current level. The fundamental criteria — rigidity and fluctuation of the fibrous membrane of the eye — do not depend on the central corneal thickness and objectively determine the current functional state of the fibrous membrane. The ability to objectively and reliably determine whether a healthy or glaucoma eye belongs to its individual IOP zone is particularly important for the polyclinic network. The time such express diagnostics takes is 0.02 seconds.
