The major blinding eye diseases, such as keratitis, cataract, glaucoma, diabetic retinopathy, seriously threaten human health and affect the quality of patients' life. Connexin 43(Cx43), as the most common connexin in vertebrates, is widely distributed in eye tissues and is involved in physiological processes such as embryonic development, metabolic regulation, tissue homeostasis, as well as pathological processes such as inflammation, oxidative stress, epithelial-mesenchymal transition, vascular leakage, and angiogenesis. Cx43 plays an important role in the occurrence and development of various blinding eye diseases. This article will review its role in the pathogenesis of the above-mentioned blinding eye diseases and the advances in targeting Cx43 therapy.
