The Study
Global trends in oxidative stress in the Retina: A bibliometric analysis of 2013–2023
This study didn't test any medicines or patients — it just counted how many science papers were written about oxidative stress and the eye. It tells us what topics scientists are talking about, not whether anything actually helps people's eyes.
Analysis score
Maximum 5 for a narrative review.
Where the score came from
Scientists have been studying how too much 'rust' (oxidative stress) in the eye causes blindness, and how antioxidants might help.

Systematic reviews and meta-analyses of cohort studies. They sit above a single cohort study but below a single randomized trial, because the underlying evidence is still observational.
Key takeaways
Summary
Based on the study abstract and findings.
- 1This shows where scientists are spending time and money — not whether antioxidants actually fix eye disease in people yet.
- 2Over 2,100 studies were published between 2013–2023; China published the most (38.6%), the U.S.
- 3had the most cited papers.
- 4Nrf2, autophagy, and mitochondria were top research topics.
- 5Sodium iodate was used in over 50 animal studies to mimic eye damage.

In retinal pigment epithelial cells, activation of the Nrf2 signaling pathway is associated with reduced oxidative damage in age-related macular degeneration and diabetic retinopathy, based on more than 100 published research studies.
From 2013 to 2023, China published the most research papers on oxidative stress in the retina, making up 38.6% of all such papers, while U.S. papers received the highest average number of citations per paper.
Between 2013 and 2023, more than 1,100 scientific papers were published on the use of antioxidants to treat retinal diseases, especially age-related macular degeneration and diabetic retinopathy.
Research on retinal oxidative stress in age-related macular degeneration consistently identifies mitochondrial dysfunction, autophagy, and inflammation as the most studied mechanisms associated with the death of retinal pigment epithelial cells.
Scientists use a chemical called sodium iodate to damage the retina in animal studies to investigate how oxidative stress causes retinal degeneration, and this method has been used in more than 50 published studies.
Higher levels of oxidative stress and lower antioxidant defenses in the retina are consistently found in people and animal models with age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa.
