科学领域:

  • 眼科医生 眼科 眼科
  • 医疗技术 医疗技术 医学技术
  • 儿科玻璃眼 儿童玻璃眼

背景情况:

  • 儿科玻璃眼管理需要准确的视野评估.
  • 传统的周边测量方法,如汉弗里场分析仪 (HFA),对儿童来说可能具有挑战性.
  • 需要新的,对患者友好的视觉现场测试方法.

研究的目的:

  • 为了比较基于iPad的周边测量应用程序,墨尔本快速场 (MRF) 的周边测量结果,与患有青光眼的儿童的汉弗里场分析仪 (HFA).
  • 评估MRF和HFA的一致性和可重复性,以评估儿科绿眼病患者视野缺陷.

主要方法:

  • 十六名患有青光眼的儿童在两次访问中使用MRF和HFA进行了视觉现场测试.
  • 平均偏差 (MD) 和模式偏差指数是主要结果指标.
  • 用回归,类内相关系数和布兰德-阿尔特曼分析来评估一致性和可重复性.

主要成果:

  • 在平均偏差方面,MRF与HFA有很强的一致性 (类内相关系数=0.91).
  • 复制系数与正常场相似,但在MRF和HFA中,对眼缺陷的重复系数更大.
  • MRF测试时间与HFA的SITA Fast相似,并且比SITA标准快得多.
