Garcia-Martin et al., from the University of Zaragoza, reported that fibromyalgia causes thinning of the retinal nerve fiber layer. In an observational, prospective study performed on 116 fibromyalgia patients and 144 controls, retinal nerve fiber thickness was evaluated by OCT. Retinal nerve fiber thickness was found to be significantly thinner in fibromyalgia patients. It has been emphasized that neurodegenerative mechanisms may play a role in the pathogenesis of the disease.
