Abstract EN
Purpose.
To report a reduction in macular ganglion cell layer and inner plexiform layer (GCL+IPL) thickness and circumpapillary retinal nerve fiber layer (cpRNFL) thickness using spectral-domain optical coherence tomography in patients with homonymous hemianopia due to posterior cerebral artery (PCA) stroke.
Methods.
Seven patients with PCA stroke were examined using Cirrus high-definition-OCT.
The GCL+IPL thicknesses were divided into the hemianopic and unaffected sides.
The relationship between the time after stroke and the GCL+IPL thicknesses in the hemianopic side was evaluated.
Results.
The average thicknesses of the GCL+IPL were 64.6 and 82.0 μm on the hemianopic and unaffected sides, respectively, and the measurement was significantly thinner on the former side ( p = 0.018 ).
A regression analysis revealed a negative linear relationship ( R 2 = 0.574 , p = 0.049 ) between the time after stoke and the GCL+IPL thicknesses on the hemianopic side.
The supratemporal and inferotemporal cpRNFL thicknesses in the eyes ipsilateral to the stroke showed a significant reduction.
Conclusion.
Our findings confirmed our previous observations that the degeneration of retinal ganglion cells can occur after PCA stroke.
GCL+IPL thinning was demonstrated in the hemiretinae corresponding to the affected hemifields.
Also, it is suggested that the retinal changes observed are progressive.
