New observations and emerging ideas in diagnosis and management of non-infectious uveitis: A review

Background: Non-infectious uveitis (NIU) is an immune-mediated disease with clinical symptoms such as eye pain, redness, floaters, and light sensitivity. NIU is one of the leading causes of preventable blindness. Objective: This review describes current and emerging therapies for NIU. Methods: PubMed searches were conducted using the terms uveitis, therapy, corticosteroids, immunomodulators, biologics, intravitreal injections, intraocular implants, and adverse events deemed relevant if they presented data relating to prevalence, diagnosis, and treatment of uveitis. Results: Diagnosis and management of NIU may require collaboration among different healthcare providers, including ophthalmologists and rheumatologists. Although many patients with NIU respond to corticosteroid (CS) therapy, long-term CS use can be associated with potentially severe adverse events. Localized CS therapies have been developed to reduce adverse events; however, some intravitreal injections and intraocular implants were linked to elevated intraocular pressure and cataracts. CS-sparing therapies such as biologics have demonstrated efficacy and safety while reducing CS burden. Biologics targeting tumor necrosis factor provide CS-sparing options for patients with NIU. Additional studies are needed to address long-term efficacy and safety of biologics targeting IL-6 and inhibitors of JAK/STAT. Conclusion: Biologics, JAK/STAT inhibitors, and improved localized therapies may provide additional options for patients with NIU.
