Delphi Panel Consensus Regarding Current Clinical Practice Management Options for Demodex blepharitis

Area of Science:

• Ophthalmology
• Dermatology
• Parasitology

Background:

• Demodex blepharitis (DB) is a common eyelid condition.
• Gaps in knowledge regarding effective DB treatment exist.
• Ocular surface disease experts convened to address these gaps.

Purpose of the Study:

• To achieve expert consensus on the optimal treatment strategies for Demodex blepharitis (DB).
• To establish clear guidelines for diagnosing and managing DB based on expert opinion.

Main Methods:

• A modified Delphi panel process was employed, involving 12 ocular surface disease experts.
• Methods included a live roundtable discussion and three rounds of surveys.
• Consensus was defined by specific Likert scale medians or agreement among 8 out of 12 panelists.

Main Results:

• Experts agreed that effective treatment should reduce the need for mechanical interventions like lid scrubs.
• Collarettes were identified as a surrogate for Demodex mites, with their reduction being the primary treatment goal.
• Treatment should be initiated for patients with at least 10 collarettes, irrespective of other symptoms, and DB can be cured with potential for reinfestation.

Conclusions:

• Consensus was achieved on key aspects of DB management, including the pathognomonic nature of collarettes.
• Treatment efficacy can be monitored by observing the resolution of collarettes.
• Increased awareness and standardized treatment monitoring will lead to improved patient care and clinical outcomes for DB.
