Visual Field Enlarged View

A nice picture of a patient’s visual field is obtained by assigning a lighter shade of gray to spots on the visual field in which a patient could see relatively weak flashes (the higher numbers in "D"), and a darker shade of gray to spots in which a patient could see only relatively strong flashes. Here it is appropriate to point out that all eyes have a blind spot (scotoma) where the optic nerve connects with the retina. It is "blind" because there are no light receptors at this point. The blind spot in the eye shown is indicated by the dark area in the lower left half in this print-out.
