Persistent fetal vasculature presenting with axial elongation and platyphakia.

Leukocoria in children should always raise the concern for retinoblastoma. However, a variety of non-neoplastic conditions can also present with leukocoria, including persistent fetal vasculature (PFV), a nonhereditary, congenital anomaly caused by a failure of the fetal intraocular vasculature to regress during development. Classically PFV presents with features that make it easily distinguishable from retinoblastoma, including microphthalmia, retrolental fibrovascular membrane, central dragging of ciliary processes, and cataract. We present an atypical case of PFV in a 9-month-old boy who presented with the unusual features of axial myopia and platyphakia.
