Three-year anatomic and visual outcomes after vitrectomy for stage 4B retinopathy of prematurity.
OBJECTIVE
To assess anatomic and visual outcome following vitrectomy for stage 4B retinopathy of prematurity (ROP) after 3 years follow-up.


METHODS
Retrospective analysis of 56 eyes (46 infants) with stage 4B ROP-related retinal detachment. Eyes underwent either lens-sparing vitrectomy (LSV) or combined lensectomy and vitrectomy (LV). Visual outcome after a minimum follow-up of 36 months was ascertained by using either Teller or Snellen acuities, or sweep visual evoked potential.


RESULTS
LSV was performed in 42.9% and LV in 57.1% of eyes. Retinal reattachment was achieved in 73.2% overall (LV 71.8% versus LSV 75%) (P = 0.96). Ambulatory vision (VA better than 20/1900) and near reading vision (better than 20/800) were attained in 97.4% and 42.8% of eyes respectively. Attached retina, LSV, and pretreatment with retinal ablation were associated with a higher incidence of near reading or better vision compared to detached (P < 0.001), undergoing LV (P < 0.001), and non pretreated eyes (P = 0.011).


CONCLUSIONS
After 3 years, more than 40% of eyes operated for ROP stage 4B in this series had a visual acuity compatible for near reading or better. Eyes undergoing LSV and with prior peripheral retinal ablation had better visual outcomes.
