Overview

Blepharitis must be differentiated from allergic contact dermatitis, conjunctivitis, trichiasis, dry eye syndrome, keratitis, hordeolum, chalazion, rosacea, and sebaceous carcinoma.

Differentiating Conjunctivitis from Other Diseases

Blepharitis must be differentiated from:

• Allergic contact dermatitis
• Allergic conjunctivitis (Atopic Keratoconjunctivitis)
• Bacterial conjunctivitis
• Viral conjunctivitis
• Trichiasis
• Dry eye syndrome
• Keratitis
• Hordeolum
• Chalazion
• Rosacea
• Superior limbic keratoconjunctivitis
• Contact Lens Complications
• Sebaceous carcinoma (should be suspected in a patient with persistent unilateral eyelid inflammation)
