要約 目的:Humphrey Matrix®による視野測定での学習効果の報告。対象と方法:視野測定を受けたことがない健常者30例30眼を対象とした。Humphrey Matrix®で,閾値測定を日を変えて4回行った。固視不良率が30%以上,偽陽性率または偽陰性率が20%以上の症例は除外し,最終的に23例を対象とした。すべて医学生または病院職員で,男性8例と女性15例であり,年齢は21~38歳(平均28歳)であった。結果:パターン標準偏差値と検査時間については学習効果がなく,平均偏差値(MD)のみ,1回目の測定値と2回目以降3回の測定値の平均間に1.46±0.92dBの感度改善があった。結論:Humphrey Matrix®による視野測定には学習効果があり,2回目以降の検査結果を用いるべきである。
Abstract. Purpose:To report the learning effect on the outcome of perimetry using Humphrey Matrix®. Cases and Method:This study was made on 30 eyes of 30 healthy volunteers. They were tested by Humphrey Matrix® on four different days. After eliminating cases with poor fixation,23 eyes of 23 cases were evaluated. All were medical students or hospital staff,consisting of 8 males and 15 females. The age ranged from 21 to 38 years,average 28 years. Results:There was no learning effect regarding pattern standard deviation or duration of examination. The mean deviation significantly improved by 1.46±0.92 dB between the first and averaged value of second to fourth examination. Conclusion:To eliminate the learning effect,it is advised to use the value obtained by second examination or later during Humphrey Matrix® perimetry.
