Comparative Study
Visual acuity outcomes with and without surgery in patients with persistent fetal vasculature.
To investigate visual acuity outcomes in patients with persistent fetal vasculature (PFV) left untreated or treated with vitreoretinal surgical techniques and to investigate clinical features associated with prognosis. ⋯ The current study indicates that approximately 50% of patients undergoing surgery for PFV will achieve useful vision. Visual acuity outcomes in patients with PFV are correlated with the nature and extent of ocular risk factors. Some patients may not be candidates for surgery because of either minimal changes or advanced disease that limit the potential of visual improvement.
