ABSTRACT
PURPOSE: To identify the incidence, risk factors, demographics, and clinical profile of dupilumab-induced ocular surface disease (DIOSD) in patients with atopic dermatitis (AD), propose a standardised treatment protocol (STP) and evaluate the response. METHODS: Prospective case series of AD patients treated in the Dermatology Department, Royal Victoria Infirmary, Newcastle upon Tyne, UK developing ocular symptoms after commencing Dupilumab between September 2018 and February 2020. A standard history and examination protocol were used including subjective symptom severity grading and Ocular Surface Disease Index (OSDI) questionnaire on each visit. Standard treatment was prescribed, and response evaluated. RESULTS: 32 of 113 included patients (28.31%) developed DIOSD, of which 20 (62.5%) were referred to the Cornea Service. Median age was 38.0 years (IQR 26.8; range 19-74). Male to female ratio was 1:1. Average time to onset of ocular symptoms from starting dupilumab was 9.2 weeks (IQR 8.8; range 0.1-40). 90% patients had bilateral conjunctival inflammation and blepharitis at presentation. Significant improvement in the subjective severity scale and the median OSDI score (from 34.0 to 10.2) was noted in response to topical eye treatment. Dupilumab was discontinued in none. CONCLUSIONS: DIOSD is not uncommon although, with timely referral and appropriate topical treatment better clinical outcome and patient satisfaction can be achieved without the need to discontinue Dupilumab. Prior allergic conjunctivitis did not affect the incidence or severity of DIOSD. Further prospective studies with longer follow-up and more focus on possible disease mechanism such as goblet cell related changes and immune response are needed.
