Purpose: Few data are available regarding the optimal treatment of multiple sclerosis (MS)-related uveitis. The aim of this study was to describe clinical features of MS-associated uveitis and determine how MS treatment affects the course of uveitis.
Methods: Retrospective, multicenter study. Patients were divided into two groups according to the use (group 2) or not (group 1) of immunomodulatory drugs. Characteristics of uveitis and treatment were reviewed.
Results: A total of 68 eyes from 36 patients (17 in group 1 and 19 in group 2) were included. All patients were treated with topical and/or systemic steroids for uveitis. Uveitis occurred 1-17 years prior to neurologic symptoms in 78% of patients. Uveitis was more severe in group 2 (p<0.05), with a tendency toward a higher rate of chronic uveitis (p = 0.06).
Conclusions: MS-related uveitis has often a favorable evolution. Patients on interferon-beta have more severe and chronic uveitis. As far as we are concerned, interferon-beta given on the sole indication of uveitis is not recommended. If steroid-sparing agent is required for intraocular inflammation, immunosuppressive drugs should be considered.
