Hippocrates (5th century BC) was the first to emphasize body hygiene and described how the condition of the nose and skin affects the eyes (\u201cnasal disorders\u201d).\nLater, Galen (2nd century AD) referred to \u201ctiny creatures\u201d of the skin, which today we recognize as microorganisms such as Demodex.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The knowledge existed\u2014but lacked a unified scientific framework.\nIn the 19th century, microscopy confirmed the presence of Demodex on eyelashes and skin.\nToday, Dermophthalmology brings this knowledge back into focus, giving it new scientific significance.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The presence of Demodex is remarkably common:<\/p>

  • 50\u201380% of the adult population hosts Demodex<\/li>
  • Higher prevalence after the age of 40<\/li>
  • Found in up to 91% of chalazia<\/li>
  • Associated with dry eye, blepharitis, chronic inflammation, and dark circles<\/li><\/ul>

    Although often unnoticed, its presence can be clinically significant\u2014especially when the eyelid\u2013skin ecosystem is disrupted.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
