Abstract
Down syndrome (DS) is associated with certain structural and functional disorders in the whole visual system. The purpose was to compare retinal and choroidal thickness using swept-source optical coherence tomography (SS-OCT) in DS subjects with controls. This cross-sectional study included 100 eyes of 52 DS subjects and 78 eyes of 39 matching age and axial length controls. Our results showed that inner or outer retinal and ganglionar thickness showed no significant differences between DS and control group (p > 0.05). However, retinal foveal thickness (rFT), ganglion foveal thickness (gFT) were significantly higher in DS group than in controls, whereas choroidal foveal thickness (cFT) and some choroidal quadrants of inner and outer rings were significantly lower (p < 0.05). This the first pilot study to provide information about macular and choroidal thicknesses in SD using SS-OCT compared to controls. Further analyses with larger numbers of subjects are needed to confirm our results.
