Coenzyme Q10 (CoQ10), a natural antioxidant produced by the human body, has strong anti-inflammatory properties, reduces oxidative stress, and improves mitochondrial function. It is also known for its strong neuroprotective effects. With age, endogenously produced CoQ10 levels decline, contributing to the development of chronic diseases, including eye disorders. Irreversible ocular diseases that result in blindness present a significant challenge in contemporary medicine, as no fully effective cure exists; current treatments primarily aim to decelerate disease progression, manage symptoms, and preserve residual vision. Our study reviews research on the use of CoQ10 in eye diseases like age-related macular degeneration (AMD), retinitis pigmentosa (RP), and glaucoma, which can cause permanent vision loss and are linked to oxidative stress and mitochondrial dysfunction. This article explores whether CoQ10 can be a safe and effective addition to treatment for these conditions. We also outline directions for future research and explain how CoQ10 functions in the studies discussed in this review.
