title: Prepapillary hemorrhage and persistent hyaloid artery.
abstract: A patient with bilateral persistent hyaloid vessels suffered a prepapillary and intravitreal hemorrhage. The clot hemolyzed and lines in the retina extended in all directions, involving the fovea. There was no vitreous separation and visual acuity was 6/6-3 (20/20-3). The patient was lost to follow-up shortly thereafter. Although persistent hyaloid vessels rarely cause intravitreal hemorrhage, they are often found in cases of persistent hyperplastic primary vitreous and must be considered possible complicating factors at surgery.
