Abstract

Purpose: To evaluate the effect of rheumatoid arthritis (RA) on choroid, retinal nerve fiber layer (RNFL), and foveal thickness using spectral domain optical coherence tomography (OCT).

Methods: Fifty patients with RA and forty-one healthy volunteers were enrolled in this study. The subfoveal, perifoveal choroidal, RNFL, and foveal thicknesses were measured by spectral domain OCT.

Results: The mean subfoveal, nasal, and temporal choroidal thicknesses in RA individuals were significantly higher than those in the control group (p ˂ 0.05). However, there was no significant difference between the RA and healthy group regarding RNFL and foveal thickness (p ˃ 0.05). A significant correlation was found between rheumatoid factor (RF) and the subfoveal temporal choroidal thickness.

Conclusion: Choroidal thickness in RA patients was higher than that in healthy participants. Choroidal thickening showed a positive correlation with RF, which may be an indicator for systemic vasculitis.

Keywords: Choroidal thickness; enhanced depth imaging optical coherence tomography; rheumatoid arthritis; vasculitis.
