Lens-sparing vitreous surgery for tractional stage 4A retinopathy of prematurity retinal detachments

Purpose. To assess the efficacy of lens-sparing vitrectomy in tractional 4A retinopathy of prematurity (ROP): retinal detachments in reducing progress ion, to stage 4B or 5 ROP. Design: Retrospective, noncomparative consecutive case series. Participants., Forty eyes (31 patients) with stage 4A ROP at 38 to 42 weeks post-conceptional age. Intervention., Lens-sparing vitrectomy. Main Outcome Measures. Retinal attachment status and presence/absence of fi xation behavior. Results. The range of follow-up was 6 to 22 months (mean, 12 months). Ninet y percent (36 of 40) of eyes showed retinal reattachment and fixation behav ior at their last follow-up visit. Conclusions: These results suggest that vitreous surgery can interrupt prog ression of ROR from stage 4A to stages 4B or 5.
