Given the increasing size of the older adult population in many countries, there is a pressing
need to identify the nature of aging-related vision impairments, their underlying …

Primates are apparently unique amongst the mammals in possessing trichromatic colour
vision. However, not all primates are trichromatic. Amongst the haplorhine (higher) primates …

The essential resource for readers needing to understand visual perception and for those
trying to produce, reproduce and measure color appearance in various applications such as …

This book describes the optical structure and optical properties of the human eye. For ease
of reference, the most commonly useful topics are at the beginning and topics with narrower …

PURPOSE: To characterize the intrinsic fluorescence (autofluorescence) of the human
ocular fundus with regard to its excitation and emission spectra, age relationship, retinal …

Melanopsin, a novel photopigment, has recently been localized to a population of retinal
ganglion cells that display inherent photosensitivity. During continuous light and following …

Using high-resolution adaptive-optics imaging combined with retinal densitometry, we
characterized the arrangement of short-(S), middle-(M), and long-(L) wavelength-sensitive …

purpose. To characterize the age-related accumulation of lipofuscin in a population of
normal subjects, resolve differences in estimated accumulation rates obtained in previous …

purpose. To evaluate the origin of the near-infrared autofluorescence (AF) of the fundus
detected by scanning laser ophthalmoscopy and compare the distribution of this AF with that …

Older adults have serious difficulty seeing under low illumination and at night, even in the
absence of ocular disease. Optical changes in the aged eye, such as pupillary miosis and …
