In the typical human visual system, the macula allows for high visual resolution. Damage to this area from diseases, such as age-related macular degeneration (AMD), causes the loss of central vision in the form of a central scotoma.

A new test designed to detect an hereditary eye disease called retinitis pigmentosa (RP) is described.

In many cases…

A review of the ophthalmologic, optometric, and psychological literature relating to the assumption that a relationship exists between reading failure and perceptual ability has found no evidence to support this assumption. (CL)

Studies demonstrate increasing glucose metabolic rates in human primary (PVC) and association (AVC) visual cortex as complexity of visual scenes increase. AVC increased more rapidly with scene complexity than PVC and increased local metabolic activities above control subject with eyes closed; indicates wide range and metabolic reserve of visual…
