摘要
目的 通过对Octopus101视野计检测的可信度分析,探讨影响检测结果可靠性的因素。方法 采用Octopus101视野计对门诊129例被检者(244眼)进行视野检查,分析被检者视野缺损程度与假反应率的关系。结果Octopus101视野计检测视野结果的假反应率(RF值)≤15％有172眼(70％);>15％有72眼(30％),其中仅有假阳性反应23眼,包括正常视野19眼(83％),仅有假阴性反应29眼,包括严重视野缺损22眼(76％)。不同视野缺损程度的被检者其假阳性、假阴性反应率有显著差异(P<0.01)。结论 RF值可以在一定程度上反应Octopus101视野计视野结果的可信度。RF值>15％者假阳性反应率高与被检者年龄小有关;而假阴性反应率高与被检者视野严重缺损和年龄大有关。因此,检查中应尽可能避免影响因素,并根据实际情况正确评价RF值的临床意义。
Objective To analyze RF values and discuss reliability tactors associated with Octopus 101 visual field analyzer. Methods The visual fields of 129 patients (244 eyes) were examined by Octopus 101. The RF values were calculated and grouped upon patients' age and severity of visual fields defects. Results Of 244 eyes 86 eyes (35%) with zero RF value and 86 eyes (35%) with RF value below 15% were recorded. Seventy-two of 244 eyes showed RF values over 15%. Twenty-three eyes with RF value over 15% were found with only false positive response, of which 19 eyes (83%) showed normal visual fields and no eyes with median to severe visual field defects. 29 eyes with RF value over 15% only had false negative response, of which 22 eyes (76%) demonstrated severe visual field defects and no eyes with normal visual fields were detected. Conclusion RF value may be used to evaluate reliability in visual field examination using Octopus 101. In patients with RF value above 15%, a high ratio of false negative response was mostly seen in the patients with severe visual field defects or older ones. A high ratio of false positive response was mostly seen in the younger patients. It is important to eliminate factors that may interfere with reliability during the examination and evaluate RF values properly in clinical practice.
