摘要
目的探讨先天性黄斑缺损的相干光断层扫描(OCT)图像特征,分析OCT对先天性黄斑缺损的诊断价值。方法回顾分析先天性黄斑缺损患者15例(20只眼)的眼底照片和OCT图像特征,进行分析总结。结果(1)OCT可显示后巩膜葡萄肿的范围和程度;(2)缺损区域脉络膜层毛细血管层光带消失;(3)缺损区域视网膜神经上皮层明显变薄,伴有神经上皮内外层间的分离,层间有低反射带;(4)缺损边缘紧密粘连;(5)缺损累及视盘时呈类似青光眼样视盘改变。结论OCT能够显示先天性黄斑缺损患者视网膜细微的形态学改变,结合眼底彩照可对该病进行全面而细致的评估。
Objective To investigate The characteristics of congenital macular coloboma of optical coherence tomography（ OCT） and its clinical application. Methods The fundus photograph and OCT of 15 cases （20 eyes ） were diagnosed as congenital maeular coloboma were analysised. Results The characteristics of OCT includes ： （ 1 ） Posterior scleral staphyloma can be showed clearly. （ 2 ）The layer of choroid capillary disappeared in the zone of coloboma. （ 3 ） The retinal neurosensory layer became thin. Split in inner retinal layers can be seen. （4）Adhension is strong at the edge of coloboma. （5 ） The coloboma includes optic disc , the optic disc assembled glaucoma. Conclusion It can be clearly shown by OCT that structure of retina and choroid in c congenital macular coloboma. It is helpful in diagnosis and treatment combine with fundus photograph.
