Whether individuals who had toxic shock syndrome (TSS) in childhood have differences in macro- and retinal microvascular parameters indicative of increased cardiovascular risk is unknown. We found no evidence of adverse macrovascular changes in 22 TSS participants compared to 60 control participants. Microvascular comparisons showed a reduction in retinal total fractal dimension which has been associated with cardiovascular risk factors in children.
