Visual Field Loss Due to Diffuse Defect |
Estimate of the portion of a patient's visual field loss that is diffuse (i.e., spread evenly across all portions of the visual field). |

|
Visual Field Loss Due to Local Defect |
Estimate of the portion of a patient's visual field loss that is local (i.e., not spread evenly across all portions of the visual field). |

Glaucoma Hemifield Test Analysis |
An analysis of asymmetry between zones of the superior and inferior visual field. It is designed to be specific for defects due to glaucoma. |

Optical Fixation Measurements |
The data output of an optical fixation monitoring process, consisting of a list of positive and negative numbers indicating the quality of patient fixation over the course of a visual field test. The value 0 represents the initial fixation. Negative numbers indicate a measuring error (i.e., the patient blinked). Positive numbers quantify the degree of eccentricity from initial fixation. |
