Post-corneal tattooing trigeminal nerve-distributed hyperpigmentation: a case report.
Article in BMC 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
backgroundkeratopigmentation is a proven cosmetic and surgical intervention for corneal irregularities or opaqueness, notably in blind eye. postoperative skin hyperpigmentation localized to a trigeminal nerve distribution has not been documented in any previous research. CASE PRESENTATION: We present a rare case of trigeminal nerve-distributed hyperpigmentation following corneal tattooing in a patient with a history of multiple procedures. Over the years, he underwent multiple ocular and periocular reconstructive surgeries. The patient initially underwent corneal tattooing in December 2014 for cosmetic rehabilitation, which yielded satisfactory results with no complaints. However, following an augmentation of the corneal tattoo in 2023, he developed hyperpigmentation of the skin localized to the ophthalmic (V1) division of the trigeminal nerve.
conclusionThis case showcases an uncommon but noteworthy dermatologic reaction following ocular tattooing, raising questions about potential pigment migration, neural-mediated skin responses, or localized inflammatory sequelae.
