Optic Neuritis in Temporal Association With Cosmetic Hyaluronic Acid Injection: A Case Requiring Differentiation From Ischemic Optic Neuropathy.

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
Visual impairment following cosmetic facial hyaluronic acid injection is frequently attributed to ischemic etiologies, but non-ischemic causes can make the diagnosis challenging. We report a case of optic neuritis that developed after hyaluronic acid injection. A 27-year-old woman developed painless visual loss and a visual field defect in the left eye several days after cosmetic hyaluronic acid injection in both cheeks. The symptoms progressed over approximately two weeks, and she was referred to our hospital. Visual acuity was 1.2 in the right eye and 0.15 in the left eye. A left relative afferent pupillary defect was present. Goldmann perimetry (GP) demonstrated a central scotoma and peripheral visual field constriction in the left eye. Fundus examination showed no abnormalities. Contrast-enhanced magnetic resonance imaging (MRI) of the left optic nerve showed hyperintensity on short tau inversion recovery (STIR) and enhancement on gadolinium (Gd)-enhanced fat-suppressed T1-weighted images. Blood tests showed no systemic inflammation, and both anti-aquaporin-4 (AQP4) and anti-myelin oligodendrocyte glycoprotein (MOG) antibodies were negative. The patient was diagnosed with left optic neuritis. She received three courses of intravenous methylprednisolone pulse therapy, followed by intravenous immunoglobulin therapy. Best-corrected visual acuity in the left eye improved to 0.7 at two months and 0.9 at four months after onset. In this case, a direct relationship between hyaluronic acid injection and optic neuropathy could not be established. However, when visual loss develops after cosmetic procedures, the differential diagnosis should include not only the commonly reported ischemic disorders but also inflammatory optic neuropathy.
