Purpose: To examine whether lens-sparing vitrectomy (LSV) is an effective surgery to treat progressive stage 4A Retinopathy of Prematurity (ROP). Methods: This was a retrospective, consecutive series of 32 eyes in 29 patients with progressive stage 4A ROP retinal detachments. Outcome measurements were retinal reattachment, foveal dragging, and cataract formation. Lowest zone of involvement, ROP staging, prior retinal surgery, and length of follow-up were also recorded. Results: Thirty of 32 eyes (94%) were reattached after one LSV. Five eyes had zone 1 disease and 27 eyes had zone 2 disease. All eyes had stage 4a disease (two had undergone a prior scleral buckling procedure). All eyes received prior laser ablation. Mean length of follow-up was one year. Two eyes had progression of retinal traction that was successfully treated with subsequent surgery. Two eyes developed cortical cataracts, one of which developed over a year after the LSV. These were treated successfully. Conclusions: LSV is a safe and effective treatment for progressive stage 4A ROP retinal detachments.
