Involvement in shared care projects requires the optometrist to make a series of decisions one of which is an assessment of the visual field data to see if there has been any progression. To aid the optometrist in making this decision, the relationship between inter-test variability in the visual field and extent of loss has been established for the Henson CFS2000 perimeter. In this study, visual field data were collected, with a supra-threshold strategy, from 174 eyes (89 patients) over a period of 2 years, there being a total of 595 visual field records. The sample included patients with both normal and glaucomatous visual fields. The results show that analysis based upon the number of stimuli missed at 5 or more dB above the threshold estimate reveals an increasing variability with extent of loss. These data can be used by optometrists to establish the significance of any change in the number of missed stimuli from one visit to the next.
参与共享护理项目要求验光师做出一系列决策，其中之一是评估视野数据，以查看是否有任何进展。为帮助验光师做出这一决策，已针对Henson CFS2000视野计确定了视野测试间变异性与损失程度之间的关系。在本研究中，采用超阈值策略，在两年时间内从174只眼（89名患者）收集了视野数据，共有595条视野记录。样本包括视野正常和患有青光眼的患者。结果表明，基于在高于阈值估计值5 dB或更多dB处漏检的刺激数量进行的分析显示，变异性随损失程度增加。验光师可利用这些数据来确定每次就诊时漏检刺激数量的任何变化的意义。
