Oooh. Pair 'em with glow-in-the-dark braces and you've got yourself a fun Halloween face.

Apparently this is not new... listed next to it on PubMed was a case report from 1981 involving autofluorescence from tetracycline and minocycline.

Minocycline can cause palpebral conjunctival greyish deposits in which autofluorescence can be readily demonstrated. We believe that this is a first report of the demonstration of in-vivo conjunctival autofluorescence of palpebral conjunctival minocycline deposit. In conclusion, minocycline deposit can be shown clinically without the need of an invasive biopsy procedure in patients with a history of blepharitis on long-term tetracycline group of medication presenting with palpebral conjunctival deposits.
