[Persistent hyperplastic primary vitreous. Middle-term results of vitrectomy].

In this study, the authors present a homogeneous series of seven children suffering from persistent hyperplastic primary vitreous, in its complete anterior and posterior form. These children were operated by pars plana lensectomy and vitrectomy. The surgical operation was beneficial in every case: not only were there no complications, but the operation also prevented progression towards neovascular glaucoma, vitreous hemorrhages and phtisis bulbi. In addition, one of the benefits of this technique was esthetic, with the disappearance of leucocoria, the occasional correction of strabismus and the reduction in microphthalmos. Visual recovery can be surprisingly good, in the absence of any associated retinal malformation.
