PURPOSE To evaluate the age-related change in contrast sensitivity seen in a middle-aged to elderly Japanese population. METHODS Contrast sensitivity and visual acuity were measured in subjects aged 40 to 79 years randomly recruited from a community in Aichi prefecture near Nagoya, Japan. Contrast sensitivity tests were performed using the Vistech contrast sensitivity test chart (VCTS 6500). The results were statistically analyzed relative to age. RESULTS A statistically significant… Expand
Effects of Ocular Dominance on Contrast Sensitivity in Middle-Aged People
The photopic and mesopic contrast sensitivity values of dominant and nondominant eyes of healthy middle-aged people were similar at all spatial frequencies, except at mesopic 18 cpd spatial frequency. Expand
Impaired contrast sensitivity among leprosy patients with normal visual acuity.
Among leprosy patients, contrast sensitivity falling outside the normative range was associated with increasing age, being female and having a grade 2 deformity, and contrast sensitivity was impaired in leproSy patients in all five spatial frequencies investigated. Expand
Normal Range of Cambridge Low Contrast Test; a Population Based Study
The normal range of Cambridge low-contrast grating test reported herein may serve as a reference for the general population in Iran and can be used for both research and clinical applications, particularly for evaluations of the outcomes of refractive surgery. Expand
Contrast sensitivity evaluation in a population-based study in Shahroud, Iran.
The present findings can be used as a reference guide for contrast sensitivity in a general population and for comparison in future studies because of the wide range variability among people with normal vision that increased at higher spatial frequencies. Expand
Measuring contrast sensitivity in normal subjects with OPTEC® 6500: influence of age and glare
The results provide baseline values for the examination of patients with different diseases in which contrast sensitivity is impaired and might be useful in studies of roadworthiness or in investigation of the impact of intraocular lenses. Expand
Relationships Between Spatial Contrast Sensitivity and Parafoveal Cone Density in Normal Subjects and Patients With Retinal Degeneration.
PCD can predict the spatial contrast sensitivity in normal subjects or patients with retinal degeneration without media opacities, and was significantly and positively correlated with the PCD in the control and retina degeneration groups. Expand
Age- and sex-related differences in contrast sensitivity in C57BL/6 mice.
Female mice have lower OKR gains than male mice, making the OKR a powerful tool to quantify contrast sensitivity, and a mutant in which plasticity in the cerebellum is impaired by expressing a protein kinase C inhibitor was tested. Expand
Does a yellow filter improve visual object categorization in normal aging?
The yellow filter globally improved the speed of categorization for the elderly participants, and the decrease in response time in the yellow filter condition was larger when the stimuli were displayed peripherally in both groups. Expand
Characterising adaptational dysfunction in age-related macular degeneration
Age-related macular degeneration (AMD) is the leading cause of visual impairment in the developed world. The prevalence of this disease will continue to increase over the coming decades as theExpand
Contrast sensitivity function and ocular higher-order wavefront aberrations in normal human eyes.
In normal human eyes, comalike aberration of the eye significantly influences contrast sensitivity function. Expand


Screening for ophthalmic disease in older subjects using visual acuity and contrast sensitivity.
In the primary care setting, a person older than 50 years of age with reduced contrast sensitivity, as determined by Arden plate 7, requires extra care in subsequent examinations because this person is likely to have an ophthalmic disease. Expand
Contrast sensitivity in different types of early lens opacities.
There was a weak, but statistically significant correlation between Contrast sensitivity reduction and cortical opacities at high spatial frequencies, and between contrast sensitivity and posterior subcapsular opacITIES at low and medium spatial frequencies. Expand

It was concluded that Vistech charts are unlikely to be of use for clinical measurements or for research studies because of low reliability. Expand
Aging and low-contrast vision: face perception.
It is reported that a daily perceptual activity, which relies on lower spatial frequency information, is also adversely affected: as compared to young individuals, many older individuals require more contrast to detect a face and to discriminate between two faces. Expand
A new comprehensive study on aging--the National Institute for Longevity Sciences, Longitudinal Study of Aging (NILS-LSA).
A new comprehensive longitudinal study of aging, the National Institute for Longevity Sciences, Longitudinal Study of Aging (NILS-LSA) started in November 1997 and by the end of September 1999, 1,643 men and women had completed their first wave examinations. Expand
