To investigate the agreement between the Oculus and Metrovision perimeters in the visual field evaluation of glaucoma patients.
In this cross-sectional study, 41 consecutive glaucoma patients were enrolled. After detailed clinical examinations, visual field testing was performed for all patients using the Oculus and Metrovision perimeters. The interval time between the two visual field examinations was 30 min.
A total of 22 participants were male (53.7%) and the mean ± standard deviation (SD) age was 58.6 ± 9.1 years. The absolute average of the mean deviation (MD) in the oculus perimeter (8.24 ± 4.92 dB) was higher compared to the Metrovision perimeter (4.02 ± 4.62; < 0.001). This difference was also evident in the Bland-Altman graph. The loss variance (pattern SD) values of Oculus perimeter (28.58 ± 16.40) and Metrovision perimeter (28.10 ± 28.45) were not significantly different; although based on the Bland-Altman plots in the lower MDs, the agreement is better and the data dispersion is lower, and in the higher MDs, the agreement is lower. The parameters of four visual field quadrants were also compared and showed poor correlations ( < 0.001).
The Oculus and Metrovision perimeter devices have good agreement in lower MDs; however, they cannot be used interchangeably.
研究Oculus视野计和Metrovision视野计在青光眼患者视野评估中的一致性。
在这项横断面研究中,连续纳入了41例青光眼患者。在进行详细的临床检查后,使用Oculus视野计和Metrovision视野计对所有患者进行视野测试。两次视野检查的间隔时间为30分钟。
共有22名参与者为男性(53.7%),平均年龄±标准差(SD)为58.6±9.1岁。与Metrovision视野计(4.02±4.62;<0.001)相比,Oculus视野计中平均偏差(MD)的绝对平均值(8.24±4.92 dB)更高。这种差异在Bland-Altman图中也很明显。Oculus视野计(28.58±16.40)和Metrovision视野计(28.10±28.45)的损失方差(模式标准差)值无显著差异;尽管根据较低MD值的Bland-Altman图,一致性更好且数据离散度更低,而在较高MD值时,一致性较低。还比较了四个视野象限的参数,结果显示相关性较差(<0.001)。
Oculus视野计和Metrovision视野计在较低MD值时有良好的一致性;然而,它们不能互换使用。
