Age-related eye disease and cognitive function

摘要: Purpose: There is growing interest in the relationship between age-related vision loss and cognitive function. Our objective was to determine if two groups with age-related eye disease have worse cognitive function than a group with normal vision using cognitive tests that do not rely on vision.Methods: We are conducting a cross-sectional hospital-based study of older adults (n= 236) having either age-related macular degeneration (AMD)(n= 65), glaucoma (n= 65), or a control group with normal vision (n= 106) in Montreal, Canada. Those in the AMD group were diagnosed with late stage AMD in both eyes with a better eye visual acuity of 20/40 or worse. Those in the glaucoma group had primary open-angle glaucoma in both eyes with a visual field mean deviation worse or equal to-4dB in their better eye. Controls had no diagnosis of AMD or glaucoma, a visual acuity better than 20/30 in both eyes and a visual field …
