The burden of non-infectious intraocular inflammatory eye diseases: a systematic literature review

Current Medical Research and Opinion. 2018 Dec;34(12):2095-2103


Non-infectious inflammatory eye diseases (IEDs), although rare, are complex and varied and may result in detrimental effects. A systematic literature review was conducted on the clinical outcome and economic burden of IED.


The Ovid search platform (Wolters Kluwer) was used to access scientific literature databases, including MEDLINE, Embase, Cochrane libraries, Health Technology Assessment and the NHS Economic Evaluation database. The search strategy targeted clinical and economic outcomes research in 2009-2016. Titles and abstracts resulting from inclusion criteria were screened, and two reviewers independently extracted relevant information from the selected full-text articles.


Thirty-nine papers met the inclusion criteria - 21 clinical trials, 7 database analyses, 6 non-systematic literature reviews with expert commentary, 3 chart reviews, and 2 surveys - which assessed steroids, immunosuppressants, implants and biologics. Patients experienced considerable morbidity, much of which was associated with corticosteroid use. The average annual healthcare costs of patients with IED were $13,728 to $32,268 in 2009 US dollars, which amounted to 3.1 to 8.3 times that of patients without IED. Steroid-releasing intraocular implants were associated with higher up-front costs, close monitoring requirements, potential for implant removal and increased rates of adverse ocular events than systemic steroids.


IEDs are rare and complex conditions that threaten eyesight and impose considerable morbidity as well as a substantial economic burden. This review confirms that further research is needed to more fully explore the burden of IED and treatment-related adverse events, as well as appropriate means for clinicians to intensify treatment.
