很多文章证实了CT扫描对研究眶部疾病的作用,而描述CT与眼部病理学有关的报道却甚少。虽然眼科学家很熟悉球后葡萄肿轴性近视,但其CT所见也极少报道。为了避免将其考虑为恶性疾患,现将该病CT所见讨论如下: 例1女性50岁,压紧性头痛9个月。过去史中,从儿童时期就有左眼弱视。物理检查:左眼见有Marcus-Gum瞳孔缺损、前凸2.5mm并下垂,仅能见到自己的手动。左眼底检查发现一大的视神经盘、玻璃体云斑和球后视网膜、脉络膜近视性退行变。右眼视觉敏感度、瞳孔功能和眼底镜检查均属正常。经碘剂静脉造影,用Elscint Exel 905型全身
Many articles confirm the role of CT scan in the study of orbital disease, and few reports describe the relationship between CT and ocular pathology. Although ophthalmologists are familiar with posterior spherical myopia, the findings of CT are rarely reported.
