ABSTRACT

Aim

To evaluate the effect of repository corticotropin injection (RCI) on regulatory T cell population in patients with noninfectious retinal vasculitis.

Patients and Methods

Patients with active noninfectious retinal vasculitis were included in a prospective nonrandomized open-label study.

Results

Eighteen patients (33 eyes) were included in the study. Eleven (61.1%) patients [20 (60.6%) eyes] and 7 (38.9%) patients [13 (33.3%) eyes] were in the responsive and non-responsive groups, respectively. We did not find any statistically significant difference within the PPP-R group, within the PPP-NR group, or between these two groups in regard to regulatory T cell population. No significant systemic or ocular complications were found.

Conclusion

RCI may be a complementary treatment in patients with non-infectious retinal vasculitis with or without uveitis. This study did not demonstrate an increase in regulatory T cell population in patients with noninfectious retinal vasculitis.

Highlights

Repository corticotropin injection (RCI) may be a complementary treatment for patients with non-infectious retinal vasculitis with or without uveitis. This study did not demonstrate a significant change in T regulatory cells population with RCI treatment.
