相干光断层扫描联合间接检眼镜在高度近视眼底评估中的应用

摘要

Objective To evaluate the roles of optical coherence tomography ( OCT) and indirect ophthalmoscope fundus examination in high myopic eyes. Methods Fundus examination with indirect ophthalmoscope after mydriasis was used to screen for severe retinopathy and compared to OCT examination. Results Among 56 cases (98 eyes), 12 eyes (12. 4%) was found to have severe retinopathy by indirect ophthalmoscopy. OCT examination identified 11 eyes with ab-normalities (detection rate was 91. 67%). Conclusions OCT could clearly detect the structure of each retinal layer (in-cluding choroid) and the type of degeneration. It also could display retinal hole, crack around the hole and the range of ret-inal detachment.%目的 探讨相干光断层扫描(OCT)联合间接检眼镜检查对高度近视眼底检查的优势.方法 散瞳后用间接检眼镜检查眼底,对有临床意义的严重视网膜病变做记录,随后对视网膜病变处视网膜行OCT检查.结果 56例(98只眼)中,用间接检眼镜检查发现有临床意义的严重视网膜病变数为12只眼(12.24%),OCT检查,能够检测到病变数为11只眼(检出率为91.67%),仅有1只眼因病变处超出OCT可视范围未能清晰扫描到图像.结论 通过OCT的检查,可清晰地观察间接检眼镜检出的病变视网膜(包括部分脉络膜)各层的细微结构,可明确变性区的类型,清晰的显示裂孔、裂孔周围视网膜浅脱离的情况以及脱离范围等.
