From: Perimetric and retinal nerve fiber layer findings in patients with Parkinson’s disease
A and B: Humphrey visual field (A) and peripapillary retinal nerve fiber layer (RNFL) thickness profile (B) of the left eye of a 67 years-old man with Parkinson’s disease. The visual field print-out shows decreased mean deviation (MD), pathological pattern standard deviation (PSD), glaucoma hemifield test (GHT) outside normal limits, and deep superior arcuate scotoma. The optical coherence tomography printout shows that the RNFL thickness is within normal limits. The marginal decrease of RNFL thickness at the superior-temporal area does not correspond to the visual field scotomas.
