目的:分析先天性视盘小凹的临床特征。方法:回顾分析8例9眼确诊的先天性视盘小凹患者的临床资料。所有患者均行眼底荧光造影(FFA)、光学相干断层扫描(OCT)及视野检查。结果:FFA影像均有造影动脉期视乳头凹陷呈暗区,显示该处无毛细血管网充盈,造影晚期可见小凹内荧光素向周围渗漏。OCT显示视乳头颞侧筛板组织缺失呈无组织反射的暗区,乳头黄斑区视网膜水肿。视野检查示生理盲点扩大以及与生理盲点相连的弓形或扇形视野缺损。结论:应用FFA结合OCT检查能确定视盘颞侧筛板组织缺失,进一步证实视盘小凹与黄斑区的沟通,还可以动态观察视盘小凹的发展。

AIM:To observe the clinical features of congenital optic disc pit.METHODS:The clinical data of 8 patients(9 eyes) were retrospectively analyzed.All patients were examined by fundus fluorescein angiography(FFA),optical coherence tomography(OCT) and visual field meanwhile.RESULTS:On FFA of all patients during the artery period,the optic disc pit presented dark area,which showed that the optic disc pit was hairless and capillary network unfilled.During the later period of FFA,fluorescein seeped from the optic disc pit to surroundings.On OCT the imperfection of sieve tissue on temporal side of optic disc presented dark area which had no reflection and optic disc macula place showed retinal edema.The visual field test showed physiological blind spot extension,bow form or fan-shaped visual field defection and damage connected with physiological blind spot.CONCLUSION:The application of FFA combined with OCT can make sure to see the sieve tissue imperfection on temporal side of optic disc and further confirm the communication of optic disc pit and macula,which can ensure the diagnosis of this disease.The combing of FFA and OCT can also make dynamic state observation of the development of optic disc pit,which can probably further explain the source of subretinal fluid and the occurrence mechanism of maculopathy.
