title: [A case of invasion of the hyaloid artery into the lens].
abstract: A 6-year-old boy with hyaloid artery invasion into the crystalline lens is reported. Both lenses had localized opacities and some brown membranous tissue attached to the posterior lens capsule. He had bilateral persistent hyaloid arteries, and in the right eye this vessel penetrated the lens capsule and invaded the lens. The lens opacity had not increased for 6 years. In persistent hyperplastic primary vitreous we can often see the invasion of fibrovascular tissue into the lens, and this process usually leads to destruction and absorption of the lens. This is an unusual case because the lens showed no significant changes for long period of time in spite of vascular invasion into the lens.
