Pseudodoubling of the optic disc is a rare clinical presentation. In these cases it is necessary to exclude retinal coloboma or atrophy following vascular or infectious diseases. We present a case of pseudodoubling of the optic disc in a woman with type 2 diabetes and arterial hypertension. Ophthalmoscopic examination of the fundus showed a disc-like lesion in the right eye and a diabetic retinopathy in the left eye. The lesion was evaluated with fluorescein angiography, neuroradiological and colour Doppler imaging investigations. Colour Doppler imaging confirmed the angiographic findings of anomalous vascularisation of the pseudopapilla and provides an analysis of the choroidal vessel anastomosis between the optic disc and the retinal lesion, revealing that the pseudodoubling in this patient was the result of a chorioretinal coloboma.
视盘假性双盘是一种罕见的临床表现。在这些病例中，有必要排除血管性或感染性疾病后的视网膜缺损或萎缩。我们报告一例2型糖尿病和动脉高血压女性患者出现视盘假性双盘的病例。眼底检眼镜检查显示右眼有盘状病变，左眼有糖尿病视网膜病变。通过荧光素血管造影、神经放射学和彩色多普勒成像检查对病变进行了评估。彩色多普勒成像证实了假性视乳头异常血管化的血管造影结果，并分析了视盘与视网膜病变之间的脉络膜血管吻合情况，揭示该患者的假性双盘是脉络膜视网膜缺损的结果。
