Vitrectomy in two cases of bilateral Terson syndrome.

We report on two patients with bilateral vitreous haemorrhage after a subarachnoid haemorrhage (Terson syndrome). We performed vitrectomy in four eyes with complete recovery of vision in three eyes; one eye had visual acuity of 1/6 due to preretinal fibrosis. The patient who had 20/20 vision in both eyes had a retinal detachment in one eye two months after the vitrectomy; this was operated upon and vision did not deteriorate.
