Review of OptometryGuarding the Keep: Managing Eyelid and Adnexal Inflammation

Eyelid and adnexal inflammation ranges from routine blepharitis to vision-threatening orbital cellulitis and sebaceous carcinoma. Recognizing the immunologic pattern behind each presentation allows clinicians to triage accurately, treat the driver, and avoid missing high-stakes masquerades.

🔬 Clinical Considerations

• Recurrent “chalazia” at the same site with madarosis or unilateral blepharitis are classic presentations of sebaceous carcinoma; biopsy is mandatory when suspicious features are present
• Demodex blepharitis drives inflammation via TLR-2 signaling; cylindrical collarettes at lash bases are the key diagnostic marker distinguishing it from anterior blepharitis
• Orbital cellulitis is a true emergency: proptosis, restricted motility, vision change, or pain with eye movement demand urgent CT/MRI and IV antibiotics; do not manage as preseptal disease
• Ocular rosacea presents differently in Fitzpatrick skin types III to VI, where hyperpigmentation and acne may obscure classic facial redness; lid telangiectasia remains a reliable lid margin clue

🎯 Practice Applications

• Biopsy any recurrent or same-site nodule with lash loss or atypical features
• Apply the R-N-R framework (Recognize, Neutralize, Remember) at every lid margin exam
• Prescribe lotilaner 0.25% (Xdemvy) or topical ivermectin for confirmed Demodex; tea tree oil derivatives are adjunctive
• Refer cicatricial or systemically driven disease (OCP, SJS/TEN) for immunosuppression before structural damage progresses
