[Vitreous hemorrhage associated with persistent hyaloid artery. Apropos of a case].

We report a case of vitreous haemorrhage from a persistent hyaloid artery that occurred to a 50 year-old patient. The case report is followed by a review of the embryologic development and a physiopathologic discussion about the origin of vitreous haemorrhage. The authors emphasize the distinction between persistent hyaloid artery and persistent hyperplastic primary vitreous.
