N6-methyladenosine (m6A) methylation/modification plays a critical role in various biological processes through post-transcriptional ribonucleic acid (RNA) modification, which involves RNA processing, nuclear export, translation and decay. Functionally, m6A modification may be involved in ocular cell growth and differentiation, stem cell identity, development, haemostasis and innate versus adaptive immunity. Aberrations in m6A methylation may mediate numerous pathological conditions in the eye, including microorganism infection, inflammation, autoimmune disease, senescence, degeneration, epithelial-mesenchymal transition, fibrosis, angiogenesis, tumorigenesis and complex eye diseases. In this review, we have discussed the relevance of m6A modification to precision medicine, stem cell directional differentiation, biomarkers of eye diseases and m6A methylation activators and inhibitors. In addition, we summarised the challenges and future research directions in the field related to visual function and eye diseases.
