The management of OGIs involves initial wound closure within 24 hours, followed by vitrectomy as a secondary surgery. However, there is a lack of consensus regarding the optimal timing of vitrectomy for maximizing visual outcomes. This meta-analysis aimed to investigate whether early or delayed vitrectomy leads to better outcomes in patients with OGIs.Methods: This review was conducted based on PRISMA guidelines. The Medline, Embase, Scopus, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases were searched (October 23, 2023). Clinical studies that used vitrectomy to manage OGIs as early (within 7 days) or delayed (8– 14 days) interventions were included. Randomized controlled trials (RCTs) and non-RCTs were appraised using the Cochrane risk of bias and JBI tools, respectively.Results: Eleven studies met the inclusion criteria and were included in the quantitative analyses. There were 235 patients with OGIs who received early intervention and 211 patients who received delayed intervention. The retina was reattached in 91% and 76% of the patients after early and delayed intervention, respectively. Traumatic PVR was present in 9% and 41% of the patients in the early and delayed groups, respectively. The odds of retinal reattachment after vitrectomy were greater in the early group (OR = 3.42, p = 0.010, 95% CI=1.34– 8.72), and the odds of visual acuity ≥ 5/200 were 2.4 times greater in the early group. The incidence of PVR was significantly greater in the delayed surgery group (OR = 0.16, p < 0.0001; 95% CI=0.06– 0.39), which also required more than one vitrectomy surgery.Conclusion: Early vitrectomy results in better postoperative visual acuity, a greater proportion of retinal reattachment, and a decreased incidence of PVR.Keywords: open globe injury, early vitrectomy, delayed vitrectomy, wound repair, traumatic proliferative vitreoretinopathy, vitrectomy timing |
