- Normal central vision field extends in a circle approximately 25 to 30 degrees on all sides of central fixation and out 60 degrees superiorly (upward), 60 degrees medially (nasally), 75 degrees inferiorly (downward), and 90 degrees temporally (laterally). There is a normal physiological blind spot, 12° to 15° degrees temporal to the central fixation point and approximately 1.5 degrees below the horizontal meridian, which is approximately 7.5 degrees high and 5.5 degrees wide. The patient should be able to see the test object throughout the entire central vision field except within the physiological blind spot.
