A study was conducted to assess retinal and choroidal characteristics in fibromyalgia (FM) patients, comparing them to healthy controls, using advanced imaging techniques called spectral-domain optical coherence tomography (SD-OCT).
The study involved 39 FM patients and 44 healthy subjects, measuring key retinal metrics like retinal nerve fiber layer (RNFL) and choroidal thickness (CT), and found that FM patients had notably thinner RNFL and CT, along with a higher choroidal vascular index (CVI).
Results indicated a relationship between severity of ocular and body pain in FM patients and SD-OCT measurements, although the use of pregabalin did not appear to influence these ocular characteristics.
