title: Pseudodoubling of the optic disc: a colour Doppler imaging study.
abstract: 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.
