The indoleamine hormone, melatonin, is produced in the pineal gland and has an essential role in many physiological functions. The pineal gland is considered to be the most important organ for producing melatonin. Nevertheless, it is important to point out that the eye is also capable of producing melatonin, and has its own circadian rhythm in producing this hormone. Melatonin is mainly produced by a subpopulation of photoreceptors in a diurnal rhythm. Numerous in vitro and in vivo studies have shown the beneficial effects of melatonin in eye-related disorders. These diseases primarily affect retinal cells, highlighting the therapeutic potential of melatonin, especially in the retina. Melatonin's ability to regulate oxidative stress response pathways and modulate the expression of antioxidant genes makes it a promising candidate for mitigating retinal cell damage. Moreover, melatonin can modulate inflammatory pathways such as NF-кB and further reduce retinal damage, as well as affecting programmed cell death such as apoptosis and autophagy in retinal cells. Therefore, the goal of this review is to explore the ways in which melatonin protects retinal cells from damage and ischemia. We discuss the mechanisms involved in order to gain valuable understanding of the possible therapeutic applications of melatonin in protection of retinal cells and treatment of retinal disorders.
