Blind spotPerimetryPupillometryVisual fieldThe pupil can be used as an objective measure for testing sensitivities across the visual field (pupil perimetry; PP). The recently developed gaze-contingent flicker PP (gcFPP) is a promising novel form of PP, with improved sensitivity due to retino...
While I am not an advocate of electrically illuminated test objects in preference to the ordinary methods now used in mapping out the visual field and the blind spot, I believe such devices have their field of usefulness and can often be employed to advantage, for example, in office or dispe...

An arcuate visual field defect connecting to the blind spot indicates that the lesion results from the damage to the nerve fiber bundle extending from the optic disc. How can we determine whether this damage is the manifestation of the acute phase of ischemic optic neuropathy (ION) or normal ...
visual field, essentially a "blind spot." In contrast, a "field defect" is a broader term encompassing any loss of vision in a part of the visual field, which could include multiple scotomas or a larger area of reduced vision across the field; essentially, a scotoma is a specific type ...
