Garcia GA, et al. - Herein, the researchers assessed the association between contrast sensitivity function (CSF), vitreous echodensity, posterior vitreous detachment (PVD), and ganglion cell complex (GCC) thickness as related to age in the same subjects. They noted PVD, vitreous echodensity, and age to be the determinants of CSF. Independent of age, PVD and increased vitreous echodensity were each related to diminished CSF. Therefore, vitreous changes could be a cause of decreased CSF with age in the absence of GCC thinning and cataracts.
