In Vivo Confocal Microscopy: A Standard Operating Procedure for the Detection of Demodex Mites at the Eyelid Margin
Published on: July 3, 2025
Abstract:
We present a case of blepharitis with symptoms lasting two years in duration and refractory to a host of prior medical treatments, including antibiotics, corticosteroids, cyclosporine, and baby shampoo. We recognized the clinical presentation as pathogomonic for demodicosis caused by the parasitic mite, demodex folliculorum, confirmed with light microscopy, and treated appropriately with tea tree oil and hygiene measures--achieving full resolution of symptoms. We highlight the presentation, treatment, and underscore demodicosis as an important, under recognized cause of blepharitis.
