However, visual response times and visual acuity did not have a significant correlation (r = 0.273) or contrast sensitivity (r = 0.273). There were some limitations to this study. There was a ...

A 66-year-old man was seen in the glaucoma clinic at Tufts Medical Center due to visual field changes, referred to neurology and then to neuro-ophthalmology with gradual left-sided peripheral ...
