高品質眼底画像はそのままで、通常の涙映画が欠かせません。不規則で劣化した涙膜が大幅イメージの質42に低下します。涙液膜の整合性を維持し、角膜の表在性点状表層角膜症を防ぐため、2 分に約非常に頻繁に目薬を使用して角膜を潤滑するが重要です。目の不透明度に関する問題がないか、細隙灯を使用し、フルオレセイン角膜の状態をチェックするストリップします...

最近数十年は、生体光音響イメージング1,2,3,4,5,6,7 のフィールドの爆発的な発展を目撃しています。 ,8。光の音へのエネルギー変換に基づく、新興の光音響イメージング縮尺が細胞内小器官、細胞、組織、器官から小動物全身に生体試料を可視化できるし、その解剖を明らかにすることができます、機能、分子、遺伝子、代謝情報1,2,9,10、11,12。光音響イメージング細胞生物学13,14, 血管生物学15,16, 神経17,18 などのバイオ分野の範囲のユニークなアプリケーションを見つけた、腫瘍19,20,21,22、皮膚23、薬理24、および血液25,26。眼科、眼は、光音響応用イメージング科学者や臨床医から実質的な興味を集めている、現在アクティブな調査中です。
対照的に定期的に使用される眼撮像技術27(FA) 血管造影とインドシアニン グリーン造影 (ICGA) (蛍光のコントラストに基づく)、光干渉断層計 (OCT) など (光散乱コントラストに基づく)、派生 10 月血管造影 (赤い血球の反対の動きに基づく)、コントラスト メカニズムとして使用して光吸収イメージング音響眼。従来眼イメージング技術とは異なる、眼組織の28の病態生理学的状態に通常関連付けられている目の光吸収特性を研究するためのユニークなツールを提供します。までに、かなり優秀な作品は、光音響イメージング29,30,31,32,33,34,35、眼で行われています。 36,37, しかし、これらの研究はラット、マウス等の小動物の目の後方のセグメントに焦点を当てます。先駆的な研究はよく眼科で光音響イメージングの可能性を示すが、ラットおよびマウスの眼球サイズ以来技術の臨床的翻訳の方に行くには長い道のりはまだははるかに小さい (1-3 未満) より人間。かなり長距離超音波の伝搬、により画像大きく目の後方のセグメントの技術を使用する場合非常に信号強度と画質が苦しみます。
この目標に向かって私たちは最近非侵襲的、報告を使用して生きているウサギのラベル無料網脈絡膜イメージング統合光音響顕微鏡 (PAM) と周波数領域 10 月 (SD 10 月)38。システムは、優れたパフォーマンス、網膜と脈絡膜内在性吸収と眼組織の散乱コントラストに基づいてより大きい動物の目を可視化することができます。家兎における予備的な結果を示す PAM がレーザー照射線量を使用して個々 の網膜と脈絡膜血管を区別して非侵襲的 (~ 80 ニュージャージー州) アメリカ規格協会 (ANSI) 安全限度以下大幅 (160 ニュージャージー) 570 でnm39;OCT は明らかに強膜、脈絡膜、網膜の異なるレイヤーを解決できます。PAM を使用してより大きい動物の後部セグメント イメージングの非常に最初のデモンストレーションで、ウサギ (18.1 mm)40の眼球のサイズがの軸の長さのほぼ 80% であることを考慮した技術の臨床的翻訳の方の主要なステップがあります。人間 (23.9 mm)。
