Fluctuating eye pressure associated with visual field deterioration in glaucoma patients
...n eye pressure may be associated with a decreasing peripheral
field of vision in patients with glaucoma, even if their eye pressure remains low overall, according to a report in the August issue of Archives of Ophthalmology, one of the JAMA/Archives journals. Prevention of further visual field deterioration i...
'Cars' imaging reveals clues to myelin damage
