Papilledema suspicion in ophthalmology practice: clinical profiles and structural-functional assessment of the optic nerve in referred cases.
Article in International ophthalmology, 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
purposeThis study aimed to determine the definitive diagnoses of patients referred to the neuro-ophthalmology unit with a preliminary diagnosis of papilledema, evaluate their clinical and demographic characteristics, and assess the structural and functional parameters of the optic nerve.
methodsThe medical records of 250 patients referred to the neuro-ophthalmology unit with suspected papilledema were retrospectively reviewed. Patients were classified as having either papilledema or pseudopapilledema. Demographic data, definitive diagnoses, symmetry and grading of papilledema, and optical coherence tomography findings (OCT), including retinal nerve fiber layer (RNFL) thickness, ganglion cell complex (GCC) values, were recorded. Visual field parameters, including mean deviation (MD), pattern standard deviation (PSD), and visual field index (VFI), were also evaluated.
resultsAmong 250 patients referred for suspected papilledema, 147 (58.8%) were diagnosed with papilledema and 103 (41.2%) with pseudopapilledema. Idiopathic intracranial hypertension was the leading cause (87.8%) in the papilledema group. RNFL thickness in all quadrants was significantly higher in papilledema cases compared to pseudopapilledema (p<0.001). Although average GCC thickness did not differ significantly, papilledema cases had lower values. Visual field analysis revealed significantly worse MD and VFI values in papilledema patients (p<0.01). Headache and transient visual obscurations were more frequent in papilledema, while pseudopapilledema was commonly asymptomatic and often associated with crowded discs or optic disc drusen.
conclusionsDifferentiating papilledema from pseudopapilledema remains a diagnostic challenge even for ophthalmologists. Accurate identification is essential to avoid unnecessary interventions and anxiety. Combining OCT and visual field analyses enhances diagnostic precision by integrating structural and functional data, supporting timely intervention to prevent irreversible visual loss in true papilledema cases.
