Is pre-operative computed tomography mandatory in the workup of open globe injuries?
Article in Emergency radiology, 2026. 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
purposeTo evaluate the necessity of computed tomography (CT) in open globe injuries after ophthalmological assessment in the emergency department (ED) prior to primary repair.
methodsA review of the medical records of patients diagnosed with open globe injuries over a 1-year period (2023-2024) was conducted. Main outcome measures were clinically relevant CT findings. Demographics and clinical characteristics of trauma were also analyzed.
results166 eyes were included. Mean age was 25 ± 16.9 years and logMAR vision 1.99 ± 0.678. 60.2% had penetrating and 5.4% perforating injuries. 60.2% of eyes had zone I injuries. OTS raw score was 50.6 ± 10.7. 34.3% of injuries were caused by metal objects and 9% were secondary to firearm injuries. 38 eyes had evidence of IOFB on pre-operative CT scan, 18 of which were metal fragments and 9 were gunshot injuries. The nature of object and type of injury were associated with IOFB presence (p<0.001 and 0.02). Iris, AC, lens and vitreous findings were all associated with the presence of IOFB (p=0.02, <0.001, 0.005 and 0.049). Intraoperatively, FBs were clinically detectable and surgically removed during primary repair in 10 patients with IOFB. In the remaining 28 eyes primary repair was performed and FB was removed after 2 weeks via pars plana vitrectomy. US done following primary repair detected 5 eyes with IOFB which had pre-operative normal CT scans. CT findings did not alter plan for initial surgical intervention in any case.
conclusionCT scan is an invaluable tool in the ED but not mandatory pre-operatively in all cases of open globe injuries following clinical examination.
