BACKGROUND: Persistent fetal vasculature (PFV) is a spectrum of congenital anomalies caused by complete or partial failure of the ocular fetal vasculature to regress. We report the visual and anatomic outcomes in a large cohort of patients who underwent early surgery for PFV. METHODS: We retrospectively reviewed the medical records of patients who underwent lensectomy and anterior or core vitrectomy for unilateral PFV without primary intraocular lens implantation through limbal or pars plana/plicata approach. Inclusion criteria were surgery prior to 7 months of age, with at least 12 months of follow-up. Eyes with severe posterior segment involvement and retinal detachment deemed beyond repair were excluded. RESULTS: A total of 58 patients met inclusion criteria. Mean age at surgery was 2.1 ± 1.5 months. Mean follow-up was 6.7 ± 4.2 years. At final follow-up, 19 eyes (33%) had visual acuity better than 1.0 logMAR. Thirty-three eyes (57%) developed 1 or more postoperative adverse events: glaucoma in 21 (36%) and retinal detachment in 11 (19%), 8 of which occurred in eyes that had pars plana or pars plicata incisions (P = 0.002). In patients with limbal incisions, 17 of 40 (43%) achieved a visual acuity better than 1.0 logMAR, compared with 2 of 18 patients (11%) with a pars plana/pars plicata incision (P = 0.03). CONCLUSIONS: In our study cohort, early surgery for PFV achieved functional visual acuity in about one-third of patients. Limbal approach to surgery may result in better visual acuity and anatomic results.
