Medial Canthal Discharge with Eyelid Eczema

Differential Diagnosis

The American Academy of Ophthalmology suggests that concurrent conjunctivitis or nasolacrimal duct obstruction are more common causes of medial canthal discharge, and should be evaluated when eyelid eczema is present 1
Eyelid eczema with discharge may indicate a secondary condition such as concurrent conjunctivitis (allergic, viral, or bacterial) 2, 3
Nasolacrimal duct obstruction can cause tear stasis and discharge, presenting with excessive tearing and minimal conjunctival redness 1

The American Academy of Ophthalmology recommends assessing discharge characteristics, such as watery, purulent, or mucoid, to determine the underlying cause of medial canthal discharge 2, 4, 6
Examination for associated findings, including conjunctival injection, follicular or papillary conjunctival reaction, and preauricular lymphadenopathy, can help diagnose conjunctivitis or other conditions 2, 3

The American Academy of Ophthalmology suggests treating both the eyelid eczema and the underlying cause of discharge, with topical antibiotics for bacterial conjunctivitis and supportive care for viral conjunctivitis 1, 2
Referral for evaluation of the lacrimal drainage system may be necessary for nasolacrimal duct obstruction 1

Mistaking discharge from nasolacrimal duct obstruction for infectious conjunctivitis can lead to inappropriate treatment, according to the American Academy of Ophthalmology 1
Failing to recognize that eyelid eczema and medial canthal discharge often represent two separate but concurrent conditions can result in inadequate treatment, as noted by the American Academy of Ophthalmology 1
