	abstract = {BACKGROUND/AIMS: To compare risk factors for poor visual outcomes in patients undergoing primary rhegmatogenous retinal detachment (RRD) repair and to develop a scoring system. METHODS: Analysis of the Primary Retinal detachment Outcomes (PRO) study, a multicentre interventional cohort of consecutive primary RRD surgeries performed in 2015. The main outcome measure was a poor visual outcome (Snellen VA <=20/200). RESULTS: A total of 1178 cases were included. The mean preoperative and postoperative logMARs were 1.1{\textpm}1.1 (20/250) and 0.5{\textpm}0.7 (20/63), respectively. Multivariable logistic regression identified preoperative risk factors predictive of poor visual outcomes (<=20/200), including proliferative vitreoretinopathy (PVR) (OR 1.26; 95\% CI 1.13 to 1.40), history of antivascular endothelial growth factor (VEGF) injections (1.38; 1.11 to 1.71), \&gt;1-week vision loss (1.17; 1.08 to 1.27), ocular comorbidities (1.18; 1.00 to 1.38), poor presenting VA (1.06 per initial logMAR unit; 1.02 to 1.10) and age \&gt;70 (1.13; 1.04 to 1.23). The data were split into training (75\%) and validation (25\%) and a scoring system was developed and validated. The risk for poor visual outcomes was 8\% with a total score of 0, 17\% with 1, 29\% with 2, 47\% with 3, and 71\% with 4 or higher. CONCLUSIONS: Independent risk factors were compared for poor visual outcomes after RRD surgery, which included PVR, anti-VEGF injections, vision loss \&gt;1 week, ocular comorbidities, presenting VA and older age. The PRO score was developed to provide a scoring system that may be useful in clinical practice.},
