Altitudinal visual field defects

This term describes a visual field defect in which either the upper or lower half of the visual field is selectively affected. The selective abnormality often creates a horizontal line across the visual field (known as “respecting the horizontal meridian”). Altitudinal defects occur in retinal vascular disease, glaucoma, and other disorders that affect the eye itself.
