Clinical characteristics, management and visual outcomes of traumatic optic neuropathy: a five-year retrospective study from a tertiary referral centre.
Observational study in BMC ophthalmology, 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
backgroundTraumatic optic neuropathy (TON) is a potentially blinding complication of craniofacial trauma with an uncertain prognosis and no established standard of care. Evidence on outcomes and prognostic factors remains limited, particularly in Southeast Asian populations.
methodsA retrospective observational study was conducted at a tertiary referral centre in Malaysia between September 2020 and August 2025. Patients diagnosed with TON were identified through medical record review. Visual acuity (VA) was categorised according to the World Health Organization (WHO) visual impairment classification. Visual outcomes at one-year follow-up were analysed using the Wilcoxon signed-rank test, and factors associated with visual improvement were evaluated using Fisher's exact test.
resultsFifty-eight patients were identified, of whom 54 had complete data for visual outcome analysis. The median age was 23.5 years, and most patients were male (82.8%). Road traffic accidents were the predominant aetiology, accounting for 86.2% of TON cases. TON occurred across all traumatic brain injury severities, with comparable distribution in mild and severe cases. At presentation, 53.8% had severe visual impairment, including 13.8% with no perception of light. There was a statistically significant overall improvement in visual acuity at one-year follow-up compared with baseline (p = 0.003). However, subgroup analysis showed no significant association between treatment modality and visual improvement. Visual improvement was also not significantly associated with age, baseline severity, timing of corticosteroid initiation, or the presence of orbital or skull fractures and intracranial haemorrhage (all p > 0.05).
conclusionVisual outcomes in TON are variable and unpredictable, highlighting the importance of early neuro-ophthalmic assessment, close visual monitoring, and appropriate counselling regarding the guarded visual prognosis. Due to the relatively small sample size of this cohort, these findings may not be generalisable to broader populations.
