Contrast sensitivity function and ocular higher-order aberrations following overnight orthokeratology.
To evaluate relationships among contrast sensitivity function, ocular higher-order aberration, and myopic correction in eyes undergoing overnight orthokeratology for myopia. ⋯ Orthokeratology significantly increases ocular higher-order aberrations and compromises contrast sensitivity function, depending on the amount of myopic correction.

Retinotopic organization of primary visual cortex in glaucoma: a method for comparing cortical function with damage to the optic disk.
To demonstrate that the relationship between the functional organization of primary visual cortex (V1) and damage to the optic disc in humans with primary open-angle glaucoma (POAG) can be measured using a novel method for projecting scotomas onto the flattened cortical representation. ⋯ Cortical activity in human V1 was altered in these six POAG subjects in a manner consistent with damage to the optic disc. fMRI is a possible means for quantifying cortical neurodegeneration in POAG.
