许多有视力丧失的视神经病变患者之病史及视野可能是不可靠的。所以眼科医生便致力于单纯依靠眼底所见以作出诊断。本文记述让五位眼科专家观察有视神经萎缩的163眼的立体彩色眼底相片。共包括9种已知的眼病。但观察者并不知道,他们仅根据相片辨认病变的特点并作出诊断。 Many patients with visual loss of optic nerve disease history and vision may not be reliable. So ophthalmologists are committed to relying solely on the fundus to see the diagnosis. This article describes a three-dimensional color fundus that allows five ophthalmologists to observe 163 eyes with optic atrophy. A total of 9 known eye diseases.
