Abstract:N6-methyladenosine(m6A), the most common, abundant, and conserved RNA modification in eukaryotic cells, regulates RNA splicing, stability, output, degradation and translation through m6A methyltransferase, m6A demethylase, and m6A methylated binding proteins. Recent studies have found that abnormal m6A methylation may mediate a variety of pathological processes in eyes and participate in the occurrence and development of metabolic, inflammatory, degenerative ocular diseases and ocular tumors, such as diabetic retinopathy, cataract, age-related macular degeneration and uveal melanoma. This review aims to summarize the roles of m6A methylation modification in ocular cells and ocular diseases, elucidate the potential molecular mechanisms of m6A methylation in ocular diseases, so as to encourage innovative approaches in the treatment of these ocular diseases.
