緑内障検診におけるHeidelberg Retina TomographⅡ（version 3.0）GPSの有用性

Usefulness of Heidelberg Retina TomographⅡ（version 3.0）in glaucoma screening

要約　目的：HRTⅡ（Heidelberg Retina TomographⅡ version 3.0）の緑内障検診における有用性の検討。対象と方法：緑内障検診に参加した710人1,420眼を対象とした。1次検診でHRTⅡ測定をし，そのGPS globalの結果を，視野と乳頭所見で判定した緑内障の臨床診断と比較した。結果：HRT測定は参加者の94.3％で可能であり，うち82.9％に信頼性のある結果が得られた。臨床診断での緑内障の疑いとHRTのボーダーラインの分類法により，感度は55.2～100％，特異性は58.6～86.4％であった。結論：GPSに基づくHRTⅡ測定は，集団検診で緑内障を検出するのに利用できる可能性がある。

Abstract.　Purpose：To evaluate the usefulness of HRTⅡ（Heidelberg Retina TomographⅡ version 3.0）in public screening for glaucoma. Cases and Method：This study was made on 1,420 eyes of 710 persons who participated in glaucoma screening program. HRTⅡ was persuaded and was processed by GPS global. Findings were compared with clinical diagnosis of glaucoma based on morphology of optic disc and visual field by Humphrey 24-2 test. Results：HRT was possible in 94.3％ of participants,of which 82.9％ gave reliable results. When compared with classification as glaucoma suspect by clinical diagnosis and guideline for borderline by HRT,the sensitivity ranged from 55.2 to 100％ and specificity from 58.6 to 86.4％. Conclusion：HRTⅡ processed by GPS global promises to be of value in detecting glaucoma in public screening program.
