Persistent fetal vasculature (PFV), or persistent hyperplastic primary vitreous (PHPV), is a congenital developmental disorder characterized by a failure of resorption of the hyaloid system. It typically presents unilaterally and has three forms: anterior, posterior, and mixed. In this case report, a seven-year-old patient, without specific personal or family medical history, was referred from the pediatric department for bilateral papilledema. The patient had a best-corrected visual acuity of 20/20 (Logarithmic Measure of Angle of Resolution (LogMAR): 0) in both eyes. Fundus examination of both eyes revealed congested pseudopapilledema with a short, mobile, brownish band extending from the optic disc towards the vitreous cavity. Ocular ultrasound of both eyes showed a fine hyperechoic line pulling on the optic nerve head, and papillary optical coherence tomography (OCT) showed a papillary traction syndrome. The diagnosis of a posterior and bilateral form of persistent fetal vasculature with papillary traction was established.
