title: Bilateral persistent fetal vasculature in an adult: Clinical manifestations and surgical outcomes.
abstract: A 23-year-old man presented with bilateral persistent fetal vasculature (PFV). Examination revealed bilateral cataracts, lens subluxation, elongated ciliary processes, and persistent hyaloid vessel remnants with mild posterior segment involvement. Extracapsular cataract extraction combined with posterior capsulectomy and anterior vitrectomy was performed in the right eye; lensectomy, posterior capsulectomy, anterior vitrectomy, superior peripheral iridectomy, and anterior chamber intraocular lens implantation were performed in the left eye. Postoperatively, the corrected distance visual acuity improved (20/100 in the right eye and 20/40 in the left eye) and the cosmetic appearance was satisfactory. This case shows that in rare cases of bilateral PFV, the natural course can be benign, with functional, although amblyopic, vision. In selected cases, late surgical intervention can improve vision and cosmetic appearance.
