This study uses fMRI to show that in glaucoma, de-afferented visual cortex responses in V1, V2, and V3 shift from negative to positive during task-related conditions, similar to macular degeneration and retinitis pigmentosa.

The paper shows that foveal pRF properties in healthy controls change when peripheral visual field stimulation is restricted, suggesting caution in interpreting similar changes in patients with visual field defects.
