The phantom array materializes when one saccades in the dark across a point light source blinking 120 times per second. One sees a stationary array of flashes--the first materializes discretely near the intended endpoint of the saccade, and subsequent flashes materia...

متن کاملDifferential associations between retinal signs and CMBs by location
OBJECTIVE To test the hypothesis that age-related macular degeneration (AMD) and retinal microvascular signs are differentially associated with lobar and deep cerebral microbleeds (CMBs). METHODS CMBs in lobar regions indicate cerebral amyloid angiopathy (CAA). β-Amyloid deposits are implicated in both CAA and AMD. Deep CMBs are associated with hypertension, a major risk factor for retinal mi...
