Research has shown that individuals with persistent amblyopia, commonly known as “lazy eye,” from childhood may have an increased risk of developing cardiometabolic disorders in adulthood. A recent observational cohort study conducted within the U.K. Biobank revealed that individuals over the age of 40 living with amblyopia were more likely to suffer from conditions such as obesity, hypertension, diabetes, myocardial infarction, and even premature death compared to their peers without amblyopia.
The study reported by Jugnoo Rahi, MBBS, PhD, MSc, and colleagues at the University College London’s Great Ormond Street Institute of Child Health emphasized the association between amblyopia and an increased risk of cardiometabolic disorders. The researchers found that individuals with amblyopia had higher odds of developing obesity, hypertension, diabetes, myocardial infarction, and experiencing premature death over an 11-year period. However, the study did not establish a causal relationship between amblyopia and these health outcomes or identify a specific underlying mechanism.
Despite the lack of definitive causation, healthcare professionals are advised to consider the long-term health implications of a childhood diagnosis of amblyopia. While not every individual with amblyopia will develop cardiometabolic disorders later in life, the study suggests an increased likelihood of such outcomes in adults who had amblyopia as children. This information underscores the importance of monitoring and addressing potential health risks associated with amblyopia early on.
Pediatrician Stephen Daniels, MD, PhD, expressed skepticism regarding the amblyopia-cardiometabolic link, citing the complexity of explaining such an association from a mechanistic standpoint. Speculation about a shared environmental or genetic factor influencing both amblyopia and cardiometabolic dysfunction was suggested, although further research is needed to explore this possibility. Common maternal and perinatal factors have been proposed as potential contributors to the observed association, pointing to the need for more in-depth investigations in this area.
The observational study conducted using data from the U.K. Biobank highlighted distinct retinal characteristics associated with amblyopic eyes, including increased venular caliber, tortuosity, and alterations in retinal fractal dimension and ganglion cell-inner plexiform layer thickness. Continued research involving larger cohorts and longitudinal studies is essential to confirm the observed association between amblyopia and cardiometabolic disorders and identify underlying factors contributing to this link. The findings from this study offer valuable insights into the potential health risks associated with amblyopia and underscore the importance of early intervention and monitoring in individuals with this visual condition.
The relationship between lazy eye and cardiovascular health represents a compelling area of study that warrants further exploration and investigation. By elucidating the connection between childhood amblyopia and adult-onset cardiometabolic disorders, researchers and healthcare professionals can work towards developing targeted interventions and preventive strategies to mitigate these risks and improve long-term health outcomes for affected individuals.
