Cell therapy for retinal disease

Abstract

Purpose of review: This review presents an update on completed stem cell therapy trials aimed at retinal diseases.

Recent findings: In recent years, several clinical trials have been conducted examining the safety and role of cell therapy in diseases, including age-related macular degeneration, Stargardt's macular dystrophy, and retinitis pigmentosa. Studies have utilized a variety of cell lines, modes of delivery, and immunosuppressive regimens. The prevalence of fraudulent cell therapy clinics poses threats to patients.

Summary: Clinical trials have begun to characterize the safety of cell therapy in retinal disease. While studies have described the potential benefits of cell therapy, larger studies powered to evaluate this efficacy are required to continue progressing toward preventing retinal disease. Nonapproved cell therapy clinics require regulation and patient education to avoid patient complications.
