Primary scleral buckling vs. vitrectomy for stage 4A retinopathy of prematurity: a systematic review and meta-analysis of surgical outcomes.
Synthesis in Eye (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
topicTo compare anatomic outcomes of primary scleral buckle (SB) vs. lens sparing pars plana vitrectomy (LSV) in treating retinopathy of prematurity (ROP) associated Stage 4A retinal detachment (RD). CLINICAL RELEVANCE: ROP is the leading cause of blindness in childhood in industrialized countries worldwide. ROP eyes with Type 1 disease can progress into tractional retinal detachment with or without a rhegmatogenous component despite early medical management with retinal ablation and/or intravitreal anti-VEGF injections, necessitating surgical management.
methodsThis systematic review and meta-analysis was registered with the Open Science Framework. A PubMed literature search was performed, and ROP-associated Stage 4A RD studies were selected based on preset inclusion criteria. Information on gestational age, age at surgery, type of surgery, and surgical outcomes were collected. Snellen visual acuity (VA) was collected when available. Postoperative anatomic success was defined as complete retinal reattachment, in which both the fovea and retinal periphery were attached. Overall, 231 eyes with confirmed ROP Stage 4A RD were collected from 24 studies. Cross-sectional analyses were used to study the rates of anatomic success and need for re-operation between eyes repaired with primary SB vs. primary LSV.
resultsThe mean gestational age was 26.0 weeks old (range 21 to 31). 152 eyes (66%) had primary LSV, 73 eyes (32%) had primary SB, and 6 eyes (8%) had combined SB & LSV. The rate of single surgery anatomic success was 84% for primary LSV, 62% for primary SB (p < 0.05), and 83% for SB & LSV. The final anatomic success rate was 91% for primary LSV, 66% for primary SB (p < 0.05), and 100% for SB & LSV. The mean logMAR VA for eyes with final anatomic success was 0.9 (Snellen equivalent of ~20/159) after primary LSV, and 1.1 (Snellen ~20/250) after primary SB.
conclusionOur study suggests that primary LSV for patients with ROP-associated Stage 4A RD offers superior anatomic results compared to primary SB. Our study provides important tools for counselling parents regarding anatomic success, and visual prognosis following surgery for ROP-associated RD.
