Ocular Injuries in Patients with Old Blowout Fractures Following Blunt Trauma.
Article in Korean journal of ophthalmology : KJO, 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
purposeTo analyze the frequency and clinical characteristics of ocular injuries in patients with prior blowout fractures who experience new blunt trauma, and to assess whether old orbital fractures provide a protective effect against subsequent ocular trauma.
methodsThe medical records of 1,315 ocular trauma patients were reviewed. A total of 927 patients who had orbital or facial computed tomography scans and ophthalmologist evaluations were considered. After applying exclusion criteria, 568 patients with 581 affected eyes were included in the final analysis. The patients were divided into two groups based on the presence of old blowout fractures, identified on computed tomography scan. The clinical characteristics and the frequency of ocular injuries were compared between the two groups. The risk of ocular injury according to the presence of old blowout fracture ware studied using multiple logistic regression after controlling age and sex.
resultsAmong the 581 eyes examined, 140 (24.1%) had old blowout fractures. The incidence of intraocular complications was significantly higher in the no orbital fracture group compared to the old blowout fracture group (20.4% vs. 2.1%, p < 0.001). Specifically, the incidence of complications such as gross hyphema (p = 0.001), globe rupture (p = 0.006), and vitreous hemorrhage (p = 0.027) was significantly greater in the group without old blowout fractures than in those with them. Multiple logistic regression showed that the presence of old blowout fractures was significantly associated with reduced risk of ocular injury (p < 0.001).
conclusionsThe patients with old blowout fractures had a lower risk of ocular injuries following subsequent blunt trauma. The findings suggest that old fractures may provide protective effect. These results may have important implications for the clinical management of patients at risk of recurrent orbital trauma.
