Central scotomas impair driving ability
Central scotomas impair driving ability

(January 23, 2013 - Insidermedicine)

From Boston - Individuals with central scotomas are less likely to identify hazards while driving, according to a report published in JAMA Ophthalmology. Researchers compared 11 patients with central field loss to 11 healthy controls. Participants had their retinal fixation loci examined while they drove in a simulator for 1.5 hours in 2 separate sessions. Results showed that those with CFL had more failures in detecting pedestrians who had appeared in areas of their visual field loss. As well, the CFL patients had a slower reaction time to pedestrians. Size of the scotoma and contrast sensitivity both predicted the outcomes, while visual acuity had no such connection.
