摘要
椭圆带是相干光断层扫描(optical coherence tomography,OCT)在外层视网膜中重要的反射层次,是判断视细胞是否健在的重要标志。多种眼底疾病会导致外层视网膜损伤,尤其是椭圆体带损伤。其中表现为可逆性椭圆体带结构显示不清或消失的疾病包括多发性一过性白点综合征、梅毒性脉络膜视网膜炎;而表现为非可逆性椭圆体带结构缺损的疾病包括急性区域性隐匿性外层视网膜病变、视网膜光损伤、Stargardt病、匐行性脉络膜炎、视网膜色素变性、癌症相关性视网膜病变等,从而造成视力下降。通过椭圆体带的完整情况可对视力的预后做出判断。
Ellipsoid zone is an important reflection layer on optical coherence tomography(OCT)in the outer retina.It is an important sign to determine whether the visual cells are alive or not.A variety of fundus diseases can lead to the damages of the outer retina,especially the damages of the ellipsoid zone.The diseases that showed reversible ellipsoid zone damge included multiple evanescent white dot syndrome and syphilitic chorioretinitis.The diseases leading to non-reversible ellipsoid zone damge include acute zonal occult outer retinopathy,retinal light damage,Stargardt disease,serpiginous choroiditis,retinitis pigmentosa,cancer-associated retinopathy,etc.These diseases cause irreversible vision loss.The prognosis of vision can be determined by the integrity of the ellipsoid zone.
