正常者におけるSITAによる初回視野検査の応答

Response time for automated perimetry with SITA in normal persons with no prior experience

要約　新しい視野測定法であるSITA-fast（SITA-F）とSITA-standard（SITA-S）のどちらが集団検診に適しているかを検討した。過去に視野検査を受けたことがない正常者80例80眼を対象とし，ハンフリー視野計のプログラム30-2を，対象の半数はSITA-Fで，残りの半数はSITA-Sで測定した。SITA-Fによる測定時間はSITA-Sによる測定時間の54％であった。信頼性の高いデータはSITA-F群の95％，SITA-S群の90％にみられた。Andersonの異常判定基準を用いた場合の特異度はSITA-Fが89％，SITA-Sが94％であり，統計学的有意差はなかった。以上のことから，正常者の多い集団検診ではSITA-FはSITA-Sよりも有用であると結論した。

Abstract.　A clinical evaluation was made regarding the usefulness of SITA algorithm for screening of glaucoma. Eighty eyes of 80 healthy persons were examined by Program 30-2 of Humphrey Visual Field Analyzer. They had no prior experience of automated perimetry. Forty persons were tested by SITA-fast algorithm and the other 40 by SITA-standard algorithm. Perimetry with SITA-fast was completed in 54％ of time necessary for SITA-standard. Reliable data were obtained in 95％ of SITA-fast group and in 90％ of SITA-standard group. After the criteria by Anderson,the specificity of data was 89％ in SITA-fast and 94％ in SITA-standard. The difference was not significant. The finding shows the usefulness of SITA-fast algorithm in mass screening for glaucoma.
