Osseous and Adipocytic Differentiations in the Intraocular Lens and Vitreous

After review of the literature, it appears that lenticular osseous replacement occurs more often than adipocytic. In addition to vascularization of the lens through a capsular dehiscence, other causes are explored, including direct epithelial-mesenchymal transformations of the lens epithelium or, less likely, of the disorganized adjacent neuroectoderm. The focus of vitreous adipose tissue may represent a transformed luxated lens extruded from its capsule, which was left behind in the pupillary zone.
