One-Year Follow-up of Retinal Nerve Fiber Layer Changes in Fibromyalgia Patients: A Retrospective Cohort Study
Öz
OBJECTIVE: To retrospectively evaluate retinal nerve fiber layer (RNFL) changes over one year in fibromyalgia (FM) patients compared to healthy controls, assess correlations between clinical parameters and RNFL measurements, and investigate potential treatment-related effects. MATERIALS and METHODS: This retrospective cohort study analyzed medical records of 44 female FM patients and 44 age-matched healthy controls who underwent serial optical coherence tomography (OCT) examinations. RNFL thickness measurements obtained using Canon-OCT HS100 at baseline and one-year follow-up were extracted from the database. Clinical data including Visual Analog Scale (VAS), Fibromyalgia Impact Questionnaire (FIQ), disease duration, and medication use were collected from patient records. Statistical analyses included Mann-Whitney U tests, Wilcoxon signed-rank tests, Kruskal- Wallis tests, and Spearman correlations.
RESULTS: No significant baseline differences in RNFL parameters were observed between groups. However, FM patients showed significantly greater RNFL thinning in nasal (Δ: -1.51±1.01 vs - 0.74±0.66 μm, p<0.001) and superior (Δ: -2.49±1.66 vs -1.09±1.08 μm, p<0.001) sectors compared to controls. Disease duration correlated positively with average (r=0.308, p=0.042) and temporal (r=0.342, p=0.023) RNFL change. Pregabalin users showed greater RNFL reduction in nasal (p=0.016) and inferior (p=0.031) sectors.
CONCLUSION: FM patients demonstrate accelerated RNFL thinning over one year, particularly in nasal and superior sectors. Disease duration influences this progression. These findings may be consistent with the hypothesis of ongoing neurodegenerative processes in FM, though the small effect sizes warrant cautious interpretation. The results highlight OCT as a potential monitoring tool.
