[Subhyaloid macular haemorrhage in Terson syndrome, treated by rupture of the posterior hyaloid using YAG laser].

CASE REPORT: We present the case of a 48 year-old man who had a sudden onset of vomiting, headache and loss of consciousness. The visual acuity was severely reduced in the left eye, with a large subhyaloid haemorrhage being observed in the fundus.

DISCUSSION: The combination of subarachnoid haemorrhage and a vitreous haemorrhage is called Terson syndrome. The details of the treatment of this case with YAG laser are also discussed.
