Do you believe the physical benefits of anabolic steroids outweigh potential long-term vascular health risks?
A cross-sectional study of 151 recreational athletes found that current anabolic steroid use is linked to changes in the structure of retinal blood vessels. These vascular differences were not observed in former steroid users, suggesting potential for recovery.
Why it matters
Researchers analyze retinal microvascular structure as a proxy for systemic vascular health to understand how performance-enhancing drugs may impact long-term cardiovascular outcomes. This study highlights a clear distinction in vascular measurements between active users and nonusers.
This cross-sectional study of 151 adult recreational athletes compared 74 active anabolic steroid users, 26 former users, and 51 nonusers. Researchers observed reduced arteriolar branching complexity and lower artery-to-vein ratios in the active user group compared to nonusers.
The players
Ophthalmology and Therapy
A peer-reviewed medical journal that publishes research on clinical developments in ocular health and vision science.
The details
Researchers used digital retinal photographs of the right eye to assess vascular health by measuring vessel width, branching, and curvature. These structural changes were identified after adjusting statistical models for factors including age, sex, and body fat percentage. While active users showed significant deviations in vessel metrics, former users showed no significant differences when compared to nonusers, indicating the potential for vascular normalization following cessation.

Health Landscape
The study contributes to the growing body of research investigating the use of retinal microvascular imaging as a biomarker for systemic cardiovascular risk. It follows the established pattern of using ocular health indicators to assess broader physiological impacts caused by performance-enhancing drugs.
If you are currently using or considering anabolic steroids, it is worth discussing the potential systemic cardiovascular implications with your physician. This research highlights the importance of routine health screenings, particularly those that evaluate vascular function, for athletes using these substances.
The takeaway
Current evidence suggests a measurable impact of anabolic steroids on retinal vascular architecture that appears to diminish after use stops. Maintaining regular checkups with a healthcare provider can help monitor cardiovascular health markers that might be influenced by supplement use.
