Multiple system atrophy (MSA) is a rapidly progressive neurodegenerative disorder relegating patients to total dependency
within several years. We explored retinal thickness changes in multiple system atrophy (MSA) patients according to disease
severity and subtypes of MSA.A total of 36 MSA (27 MSA-P and 9 MSA-C) patients and 71 control subjects underwent general
ophthalmologic examination and optical coherence tomography (OCT) scans. Peripapillary retinal nerve fiber layer (RNFL)
thickness and perifoveal retinal thickness were analyzed separately. MSA patients showed significantly decreased superior,
inferior, superotemporal and inferotemporal RNFL thickness and showed significant perifoveal thinning in the superior and
inferior outer sectors compared to control. Both the RNFL and perifoveal thinning were more marked and widespread in
MSA-P than MSA-C patients. The UMSARS scores and the GDS showed a consistent and significant negative correlation with
perifoveal thickness. In conclusion, peripapillary RNFL and perifoveal retinal thinning is observed in MSA which may reflect
the degree and pattern of neurodegeneration occurring in MSA.
