The document discusses messages from the Glaucoma Hemifield Test (GHT) performed on the Humphrey Field Analyzer. The GHT compares sensitivities between the upper and lower halves of the visual field. An "Outside Normal Limits" message indicates significant differences, while a "Borderline" message means differences are greater than normal but not significant. Other possible messages include "General Depression of Sensitivity" if points are abnormally low or "Abnormally High Sensitivity" if points are abnormally high. A "Within Normal Limits" message means no significance limits were reached.
