[Demodex folliculorum a hidden cause of blepharitis].

UNLABELLED: Meibomian gland dysfunction (MGD) is a common cause of dry eye disease. Demodex mites can cause MGD with symptoms like itching, dryness and general ocular discomfort. It is important to consider infestation with Demodex mites in individuals who are non responsive to traditional MGD treatment but also equally important when cylindrical dandruff is seen at the base of the eye lashes.. We report two individuals who had not responded to ocular and systemic treatment for MGD and were then diagnosed with Demodex mites. Treatment with BlephEx and Tea tree oil was successful. This is the first report on Demodex folliculorum in Iceland where a genetic analysis was done.

KEY WORDS: Demodex, blepharitis, debris, tea tree oil, dry eye. Correspondence: Sigurlaug Guðrún Gunnarsdóttir [email protected].
