Tree-Ring Sign: Progression of Retinal Detachment Secondary to Persistent Fetal Vasculature

Abstract

A baby boy was diagnosed with right persistent fetal vasculature stalk tethering to cataractous lens (Fig A). He developed glaucoma, and the resulting eye growth caused traction on the stalk and progressive tractional retinal detachment (Fig B). He was treated with goniotomy followed by lensectomy, pars plana vitrectomy, and amputation of the stalk (Fig C). The tree-ring pattern of pigmentation documenting the stages of retinal detachment was easily visible postoperatively (Fig D). (Magnified version of Fig A-D is available online at www.aaojournal.org).
