目的：应用傅里叶域相干光断层扫描（ Fourier-domain optical coherence tomography ，FD-OCT）对眼底血管造影正常的患者眼底黄斑区进行观察，寻找患者自述视物遮挡的原因。方法：对符合病情的患者询问病史，进行视力检查，裂隙灯眼前节检查，直接（间接）检眼镜检查眼底，眼底照相，眼底血管荧光造影，视野， OCT等检查。结果：7例患者（共9只眼），其中1例机械性外伤，1例日光性损伤，2例激光笔照射，3例电弧光损伤。矫正视力：0．3～1．0之间。5例患者进行FFA，结果正常（其余2例拒绝进行FFA检查），7例患者均进行视野检查，无异常。眼底检查6眼黄斑区有黄色圆形病灶。 FD～OCT检查发现7例患者（9眼）均存在黄斑区IS/OS层及椎体外节与RPE绒毛结合部断裂，形成细小囊腔。结论：FD～OCT能够准确观察到黄斑区微小结构变化，为临床诊断疾病提供重要的诊断依据。

Objective:Using FD-OCT to observe macular area in patients with normal FFA , finding the causes of vision shade Meth-ods:Patients who conformed diagnostic criteria were analyzed .Each subject underwent medical history and visual inspection ,Direct ( indi-rect) ophthalmoscopy slit -lamp examination ,fundus photography,FFA, visual field test ,OCT and so on .Results:7 patients (a total of 9 eyes), 1 case was mechanical trauma , 1 case was actinic damage ,2 cases were laser irradiation , three cases were the arc light injury . Corrected visual acuity:between 0.3 -1.0.5 cases of patients with FFA, were normal (the remaining two cases refused to do FFA checking ) ,the perimetries of all the 7 patients were normal .Fundus examination showed that 6 eyes had yellow circular lesions in macular area .FD-OCT revealed that 7 patients (9 eyes) had macular IS /OS layer and the outer segment of vertebral body seperated from RPE villus junction, and then formed small cysts.Conclusion:FD -OCT could accurately observe small structure change of the macular area ,to provide important diagnostic basis for clinical.
