Use of immunomodulatory treatment for non-infectious uveitis: an International Ocular Inflammation Society report of real-world practice

Abstract

Background: Non-infectious uveitis is a diverse group of inflammatory conditions that collectively account for substantial blindness worldwide. Expert guidelines and results of clinical trials guide treatment, but real-world clinical care is impacted by additional factors. In 2023, an international group of uveitis-specialised ophthalmologists formed the International Study Group for Systemic Immunomodulatory Drug Treatment of Non-Infectious Uveitis to report current practice.

Methods: 221 study group members from 53 countries completed a 30-item questionnaire on their management of non-infectious uveitis including: indications for and investigations prior to initiating systemic immunomodulatory drugs, use of conventional and biological drugs, and follow-up of treated patients.

Results: Major indications to initiate systemic immunomodulatory drugs were: uveitis not controlled with oral prednis(ol)one (n=208, 94.1%), specific uveitis diagnosis (n=197, 89.1%), and patient intolerance of oral prednis(ol)one (n=186, 84.2%). All members (n=221, 100%) performed pretreatment screens including: blood chemistry (n=217, 98.2%), blood examination (n=207, 93.7%), and Quantiferon assay (n=196, 88.7%). Eight conventional and 14 biological drugs were prescribed: methotrexate was the preferred conventional drug overall (n=126, 57.0%) and for 9 of 11 uveitides, and adalimumab was the preferred biological drug overall (n=216, 97.7%) and for 11 of 11 uveitides. When drugs were combined, methotrexate plus adalimumab was most popular (n=158 of 188 members, 84.0%). Patients with inactive uveitis were typically evaluated and screened for drug toxicity every 6-12 weeks (n=161, 72.9%, and 165, 74.7%, respectively).

Conclusion: Our report describes practice patterns of a large international group of uveitis specialists treating non-infectious uveitis with systemic immunomodulatory drugs.
