Optic disc haemorrhages in posterior vitreous detachment.

Posterior vitreous detachment (PVD) is a common clinical entity but is not often associated with a significant ocular disorder. Optic disc haemorrhages are rarely associated with a PVD and are more commonly associated with other local or systemic disease. The symptoms of a PVD, combined with a careful examination of the vitreoretinal interface allows a confident diagnosis of secondary disc haemorrhage to be made. Two cases of acute symptomatic PVD complicated by disc haemorrhage are presented.
