Risk in cataract surgery by palpebral infestation of Demodex folliculorum and its prevalence, review of the diagnostic technique

Abstract:

Introduction Cataract is a disease commonly observed in patients older than 60 years. Demodex folliculorum is the main microscopic ectoparasite founded in the human skin. Its infestation rate increases with age reaching 68 to 100% in the population over 70 years. Demodex folliculorum is associated with blepharitis and also considered a vector for germs. Aim To analyze the prevalence of Demodex folliculorum palpebral infestation in patients scheduled for cataract surgery and possible consequences. Methodology Eighty seven consecutive patients scheduled for cataract surgery with implantation of intraocular lens were considered for the research. An eyelash was epilated and observed under the light microscope to determine the presence of Demodex folliculorum. Results Seventy two patients (82.7%) resulted infested with the ectoparasite. A single patient coursed with the formation of an inflammatory pupillary membrane in the immediate postoperative period that resolved with topical steroids. Conclusions There was no association between palpebral infestation with Demodex folliculorum and serious postoperative complications following cataract surgery, but this does not mean that these patients would not present other implications related to the infestation.
