目的 探讨相干光断层成像(OCT)检查对视盘小凹的临床意义.方法 对6例(6只眼)视盘小凹患者进行回顾性研究,全部病例均采用OCT进行扫描,详细分析患者视盘、乳头黄斑束区及黄斑区的结构改变.结果 OCT显示全部6例患者视盘表现为颞侧筛板组织缺失,呈无组织反射的暗区,5例视盘小凹与视网膜劈裂腔之间有光学空腔相连,伴有黄斑区神经上皮浆液性脱离,2例有脉络膜缺损.结论 由于OCT是横截面成像,能在活体上观察视盘小凹患者的视盘、乳头黄斑束区、黄斑区视网膜各层次的改变;因而OCT在视盘小凹的发病机制、诊断、随访中有重要临床意义.%Objective To explore the clinical significance of optic disc pit by optical coherence tomography ( OCT ). Methods 6 patients( 6 eyes ) proved optic disc pit were subjected to OCT and their changes of optic disc and macular structure were analysis. Results OCT test Results showed that 6 eyes' optic disc temporal side lacked of crihriform plate tissue; and there were optical cavity between optic disc pit and retinoschisis cavity, accompanied with serous neuroepithelium detachment in macular area in 5 eyes; and 2 eyes had collyriculum choroid. Conclusion In ohserving the structure changes of optic disc and macular area in optic disc pit, OCT has become a kind of essential approach.
