To compare Humphrey Matrix (Matrix) with Octopus perimetry for assessing visual field (VF) indices, size, severity, and location in the glaucomatous VF defect.
Matrix (30-2 threshold program) and Octopus 1-2-3 perimetry (G1X program) were conducted on 60 eyes of 60 patients with primary open-angle glaucoma. The VF indices derived by Matrix (mean deviation, pattern standard deviation), and Octopus (mean defect, square root of loss variance, corrected loss variance) were compared, as were the size (percentage of points depressed < 5% or < 1%) and the severity (score and Hodapp-Parrish-Anderson grade) of the VF defect.
Matrix and Octopus results agreed well overall for VF indices, size, severity, and locations of the VF defect. The mean deviation and pattern standard deviation in Matrix were significantly higher than the mean defect, square root of loss variance and square root of corrected loss variance in Octopus. On the total deviation plot, the size of the VF defect in the superior and nasal fields reported by Matrix was significantly higher than by Octopus. The VF defect score by Matrix was significantly higher than that by Octopus in the superior, nasal, and whole fields. More eyes had a worse grade by Matrix than by Octopus.
Matrix compared well with Octopus in detecting glaucomatous visual field defects. However, the defects reported by Matrix were larger and more severe than with Octopus.
比较 Humphrey Matrix（矩阵）与 Octopus 视野计在评估青光眼视野缺损的视野指数、大小、严重程度和位置方面的差异。
对 60 例原发性开角型青光眼患者的 60 只眼进行了 Matrix（30-2 阈值程序）和 Octopus 1-2-3 视野计（G1X 程序）检查。比较了 Matrix（平均偏差、模式标准差）和 Octopus（平均缺损、均方根损失方差、校正损失方差）得出的视野指数，以及视野缺损的大小（<5%或<1%的点数压低百分比）和严重程度（评分和 Hodapp-Parrish-Anderson 分级）。
总体而言，Matrix 和 Octopus 的视野指数、大小、严重程度和视野缺损位置结果较为一致。Matrix 的平均偏差和模式标准差明显高于 Octopus 的平均缺损、均方根损失方差和校正损失方差。在总偏差图上，Matrix 报告的上象限和鼻侧视野的视野缺损大小明显大于 Octopus。Matrix 的视野缺损评分明显高于 Octopus 在上方、鼻侧和整个视野的评分。Matrix 报告的视野缺损程度比 Octopus 更差的眼数更多。
Matrix 在检测青光眼视野缺损方面与 Octopus 相比表现良好。然而，Matrix 报告的缺损比 Octopus 更大、更严重。
