Recognizing Demodex Blepharitis: Prevalence, Diagnosis, and Clinical Impact

Prof. Nanavaty defines Demodex blepharitis and explains how colorette counts are used to categorize severity. He shares findings from his UK study showing that nearly 60% of routine ophthalmology patients had at least one colorette and approximately 25% had moderate-to-severe disease. He discusses the case for making colorette assessment a routine part of slit-lamp exams, and addresses why the condition remains underdiagnosed and frequently misattributed to generic blepharitis.
