Purpose: This study was designed to see if lens-sparing vitrectomy could be used in selective cases of persistent fetal vasculature syndrome. Methods: Four eyes of four children with persistent fetal vasculature syndrome, where the findings were primarily posterior with an anterior attachment of the stalk to the lens eccentric from the visual axis, underwent lens-sparing vitreous surgery. All four of these children presented at an older age than the usual persistent fetal vasculature syndrome child (7-9 months) and instead of presenting with leukocoria presented with strabismus. Results: With an average follow-up of 28 months, all the lenses have remained clear and resulted in visual improvement as expressed by straightening of eye position. The children were too young at the time of this report to undergo Snellen visual acuities, but did show fixing and following behaviors. Conclusion: Lens-sparing vitreous surgery can be useful in selective cases of persistent fetal vasculature syndrome. Specifically, those eyes where an eccentrically inserted anterior stalk spares the visual axis and this stalk exerts posterior traction on the retina leading to distortion of the retina or frank retinal detachment.
