There appears to be a significant association between body weight, specifically preobesity and obesity, and changes in retinal thickness, according to a study that suggests individuals who are preobese, even without hyperglycemia, tend to have thicker central macular regions, while obese individuals exhibit thinner retinas.
The comparative cross-sectional study, which involved 131 participants, categorized individuals into 3 groups based on their BMI: normal (18.5-24.9 kg/m²), preobese (25-29.9 kg/m²), and obese (>30 kg/m²). All participants underwent comprehensive ophthalmological examinations, including optical coherence tomography (OCT) to assess retinal thickness.
There were significant differences in retinal thickness among the groups. Notably, the central foveal thickness was found to be higher in the preobese group compared to both normal and obese individuals. Conversely, obese participants exhibited thinner retinas compared to their counterparts.
