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.

The paper investigates visual cortex plasticity in a rare case of optic chiasm hypoplasia, finding three hemifield maps in one hemisphere and suggesting developmental re-wiring supports their function.

The paper tests simultaneous IOP and PERG measurements during LDP and finds IOP changes affect PERG amplitudes in lower eyes.

This paper introduces micro-probing (MP), a method to map neuronal subpopulation receptive fields in humans using fMRI without prior assumptions, revealing subpopulations in both healthy and diseased states.

The paper investigates visual cortex structure and connectivity in albinism using fMRI and pRF mapping, finding equivalent hemifield representations and altered cortico-cortical connections in V3.

This paper uses diffusion MRI to detect and quantify crossing fiber abnormalities in the optic chiasm of individuals with albinism, showing improved detection with optimized streamline filtering methods.
