Retinal Structure Injury in MS
Mult Scler Rel Dis. ePub Feb 12. Seraji-Bozograd N.
African Americans with multiple sclerosis (AAMS) have greater retinal structure injury than Caucasians with multiple sclerosis (CAMS), irrespective of history of acute optic neuritis (AON). This according to a study of 234 patients with MS, including 149 CAMS and 85 AAMS, and 74 healthy controls, including 60 CA and 14 AA. Researchers found:
• Peripapillary retinal nerve fiber layer (pRNFL) was thicker in AA vs CA healthy controls (100.9 vs 97.00 mm).
• Compared to healthy controls, patients with MS had thinner pRFML, and lower total macular volume (TMV), macular RNFL, ganglion cell layer (GCL), and inner plexiform layer (IPL).
• AAMS had thinner pRNFL (87.2 vs 90.0 mm), and lower TMV (8.2 vs 8.4 mm3), RNFL (0.73 vs 0.79 mm3), and GCL (0.94 vs 0.98 mm3) vs CAMS.
• Sub-analysis of patients without history of AON showed thinner pRNFL (88.9 vs 93.1 mm) and TMV (8.2 vs 8.5 mm3) in AAMS vs CAMS.
