Dupilumab-associated blepharoconjunctivitis.

To report a case of dupilumab-associated blepharoconjunctivitis.A 48 year-old Caucasian male presented with bilateral blepharitis, multiple chalazia, dry eye disease and significant papillary conjunctivitis. The past medical history included fourteen years of severe atopic dermatitis. After failed attempts to treat atopic dermatitis with topical corticosteroids, the patient enrolled into a four-year clinical trial of biweekly dupilumab injections. Four to six weeks after initiation of dupilumab, the patient reported blurred vision, ocular irritation and redness. Slit lamp examination demonstrated bilateral meibomian gland dysfunction, edematous eyelids with multiple chalazia and significant papillary conjunctivitis. Meibography by Lipiscan revealed significant truncation, atrophy and bifurcation of meibomian glands bilaterally. The patient's multiple chalazia were excised and eyelid hygiene was closely followed. Cliradex wipes and Avenova were added to the patient's regime and one session of Lipiflow treatment was administered. The patient continued this eyelid hygiene regimen along with neomycin/polymyxin B/dexamethasone ophthalmic ointment after each dupilumab infusion.Five weeks after Lipiflow treatment with concomitant use of Cliradex and Avenova, visual acuity and ocular discomfort improved. Current treatment includes Cliradex eyelid wipes along with neomycin/polymyxin B/dexamethasone ophthalmic ointment for a week after each dupilumab infusion. Topical steroids and antibiotics with eyelid hygiene are effective ways to treat atopic dermatitis patients exhibiting dupilumab's ocular side effects. Lipiflow therapy may also help in treatment.
