Abstract
Description
<1.緑内障チューブの構成>
本実施形態に係る緑内障チューブ1は、図1に示されるように、管部2及び変位体3等を少なくとも備える。管部2は、眼内の房水が流通するチューブである。なお、管部2は、当該管部2の入口部2Aが眼球内に位置するように施術される。
本実施形態に係る緑内障チューブ1は、2021年に開催されたWorld Glaucoma Congress(世界緑内障会議)におけるフィルムフェスティバルで世界第3位を受賞した動画に示された知見を基礎とするものである。
https://www.youtube.com/watch?v=srLSBEmm4Ew
上記動画の内容を詳述した論文は、以下のURLにて参照可能である。
https://journals.lww.com/md-journal/Fulltext/2021/07090/Heart_rhythm_synchronized_fibrin_flap_in_a.50.aspx
なお、World Glaucoma Congress(世界緑内障会議)とは、緑内障科学とケアのための独立した、公平な、倫理的な、グローバルな組織である。そして、世界緑内障会議の主な目的は、世界中の緑内障をなくすことである。
上述の実施形態では、変位体3と管部2とが一体化されていた。しかし、本開示はこれに限定されない。すなわち、当該開示は、例えば、変位体3と管部2とが別体であってもよい。
