Abstract
The case concerns a 20 year-old woman with a sudden visual loss in her left eye. In the fundus examination, a focal pre-retinal haemorrhage was observed in the superior temporal vascular branch with accompanying vitreous haemorrhage. There was a favourable spontaneous outcome. Eighteen months later, she presented with a new visual loss in the same eye, showing a sub-hyaloid pre-macular haemorrhage that was satisfactorily drained by hyaloidotomy using a Nd-YAG laser. The patient had also presented with an upper digestive tract haemorrhage and menorrhagia. A haemostasis study was performed that showed a coagulation factor VII deficiency. This is a very uncommon disorder that has not been previously described in association with the appearance of pre-retinal haemorrhages.
