망막 박리 및 망막 열공 retinal detachment, retinal tear 정의 망막의 파열은 모양과 성질에 따라 원공(hole), 열공(tear), 해리(dialysis)로 구분하는데 이 중 가장 흔한 것이 열공이다. 이 망막 열공은 망막과 유리체(vitreous; 초자체, 안구 내부를...

이를 통해 망막 하로 이동하여 망막박리를 일으키는 매우 중요한 역할을 합니다. 망막박리를 유발시키는 망막열공(retinal break)은 원공(hole), 해리(dialysis), 열공(tear)을 들 수 있습니다. 근시와도 밀접한 관계가 있는데 특히 고도근시에서의 망막...
