Clinical Presentations, Management, and Factors Affecting Outcomes in Posterior Segment Open Globe Injuries: An Analysis of 2,360 Eyes.

Introduction: The aim of the study was to report the clinical presentations, management, and factors affecting the outcomes of posterior segment open globe injuries in 2,360 consecutive eyes.

Methods: This was a retrospective, consecutive, non-comparative interventional case series. All cases with scleral and corneoscleral wounds presenting to these centers from January 2014 to January 2021 were included. The cases were defined according to the Birmingham Eye Traumatology Terminology system (BETTs) classification. The Ocular Trauma Score (OTS) was applied to the dataset.

Results: Mean age of presentation was 36.63 ± 19.92 years (median 35 years). Penetrating trauma accounted for 70.92%, rupture for 18.6%, perforation for 4.60%, and IOFB in 5.88% eyes. In 76.60%, the location of injury involved zone 1 extending till zone 2, while in 23.40% it involved zone 2 and/or zone 3. Vision at presentation was logMAR 3.03 ± 0.99 and at the last visit was logMAR 2.47 ± 1.42 (p < 0.0001). Time interval between presentation to the treatment center and globe repair was 13.93 ± 19.56 h (median 7.60 h). Favorable functional outcomes were seen in 29.20% eyes and favorable anatomic outcomes in 66.90%. Decreasing age at presentation, penetrating injury instead of rupture or perforating injury, a higher OTS, absence of corneal involvement, absence of retinal detachment at presentation, and absence of concurrent orbital fracture were associated with a favorable functional outcome (>20/200). Final visual acuity in logMAR correlated with the OTS value calculated at presentation.

Conclusions: In the absence of retinal detachment and orbital fracture, posterior open globe injuries typically have a favorable functional outcome. OTS correlated with the final visual acuity.
