Description
(a)OSDI問診の完了;
(b)日誌の確認;
(c)TearLab(商標)を用いた涙液浸透圧の測定;
(d)視力測定(BCVA、矯正視力);
(e)眼の前眼部のスリットランプ評価(生体顕微鏡);
(f)シルマー‐1試験による涙液分泌の測定;
(g)眼内圧の測定;
(h)角膜感受性の測定;
(i)10秒未満の値の場合に3回連続して実施するフルオレセインでの涙膜破壊時間試験(FBUT)による涙膜安定性の測定;;
(j)オックスフォード比色パターンに従った眼表面の評価。
試験終了処理により観察期間を終了した。
1.吸収紙を下眼瞼の縁上で、初めはの右眼、次に左眼の外眼角に挿入する。
2.患者に眼を閉じるよう求める。
3.5分後、折りたたみ部分を除いた、紙の湿った部分の長さを測定する。
1.右眼の球結膜嚢内に防腐剤を含まない2%のフルオレセインナトリウム2μLを、反射的な流涙を誘導しないように注入する(滅菌チップを備えたマイクロピペットの使用を推奨)。
2.患者に通常4~5回瞬きすることを求め、次いで瞬きせずにフルオレセイン注入から10~30秒後に、患者に眼を開いたまま真っ直ぐ前方を見るように求める。
3.12倍率のスリットランプを観察し、一定の強度のバックライト(コバルトブルー光)を維持し、角膜全体にわたる涙膜の観察を容易にする(黄色フィルターを用いる)。
4.最後の瞬きと、最初の乾燥スポットの発生又は最初の乾燥領域の出現との間の時間を記録する。
5.FBUTを観察した後、オックスフォードスキームに従って階級付けする。
6.左眼に対して工程1~5を繰り返す。
1.反射性涙液を刺激することを避けながら、外眼角中の涙液メニスカスに試験カードを当て;涙液試料を回収する;
2.装置ディスプレイ上の浸透圧値を読み取る。
表1に試験スキームをまとめる。
