Loss of Superior Half of Visual Field is rated by the U.S. Department of Veterans Affairs under DC 6080 of 38 CFR § 4.77, DC 6080 across 1 severity tier (10%). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303.
Loss of the upper half of the visual field in one or both eyes (superior altitudinal defect). Most commonly caused by branch retinal artery occlusion of inferior vessels or inferior occipital cortex injury. The schedule rates both bilateral and unilateral superior loss at 10% — functionally less disabling than inferior loss (which rates 30% bilateral), reflecting the asymmetric impact of upper vs. lower field on reading and ambulation.
