title: Optic disc neovascularization associated with ocular involvement in acute lymphocytic leukemia.
abstract: A case of vitreous involvement in acute lymphoblastic leukemia associated with neovascularization of the optic nerve head is presented. The diagnosis was made from a vitreous biopsy specimen obtained by pars plana vitrectomy and prepared by a membrane filter and modified Papanicolaou stain technique. Fibrovascular membranes and leukemic cells were seen on microscopic examination of the vitreous biopsy specimen. Retinal neovascularization associated with acute lymphoblastic leukemia is discussed.
