Ultrasonographic assessment of optic nerve: does it help in lupus-induced optic neuropathy?
Observational study in Lupus science & medicine, 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
objectiveEvaluating the potential role of neuromuscular ultrasonography (NMUS) in assessing optic nerve affection in patients with systemic lupus erythematosus (SLE), compared with healthy controls and other conventional strategies in diagnosing optic neuropathy.
methodsWe conducted an observational cross-sectional study comparing patients with SLE and a healthy group. We measured the optic nerve diameter (OND) and optic nerve sheath diameter (ONSD) and calculated the OND/ONSD ratio and side-to-side difference. An ophthalmologist examined all lupus patients and visual evoked potential (VEP) was performed to help evaluate the rule of NMUS in lupus-induced optic neuropathy.
resultsIn this study, we include 140 subjects, 65 lupus patients and 75 controls. Significant enlargement was present among lupus patients OND and ONSD (p= 0.017, 0.004, respectively) in comparison to controls; ultrasonographic evaluation had a high specificity when compared to ophthalmological evaluation and VEP reaching 89.6% and 88.1%, respectively, but with very low sensitivity.
conclusionUltrasonographic evaluation of the optic nerve may add significant value to the diagnosis of optic neuropathy in patients with SLE and should be considered a complementary tool to other conventional methods.
