regular astigmatismPURPOSE. To investigate the changes in irregular and regular corneal astigmatism with age in eyes that underwent cataract surgery (surgery group) and in eyes that did not undergo surgery (nonsurgery group).Hayashi, KenKawahara, SumieManabe, Shin-ichiHirata, AkiraInvestigative ...
• Peripheral vision –As we age we lose between one and three degrees of vision, off the edges of our sight, for every 10 years we live. Peripheral vision allows us to catch movement out of the corner of our eyes, which can be a key factor in playing sports or driving safely. ...
The contrast sensitivity was also reduced in proportion to the age. The amplitude of apparent accommodation in eyes with a monofocal IOL decreases significantly in proportion to age, resulting in worsening of best-corrected intermediate and near visual acuities. 展开 ...
EEG coherence changes during finger tapping in acallosal and normal children: a study of inter- and intrahemispheric connectivity The EEG inter- and intrahemispheric coherences (ICoh and HCoh) in the θ , α and β bands were studied in an acallosal group (ACCG) of five children and.....
It’s a fact: With age, your body will change. “There is a decline in muscle mass and there is a decline in muscle strength and there is a decline in bone density,” Ferrucci says. But you have the power to affect some of these changes. ...
The proportion of patients with corneal curvature < 40 D was 4.18% in 1970s, 5.73% in 1980s, and 3.38% in 1990s, which were significantly higher than those of other age groups. The average axial length of the eyes among primary school students was 23.96mm, and among college students, ...
Drusen are seen in a majority of eyes with AMD in both the mid and far periphery, whereas pigment changes and features of advanced AMD are less frequent. Age-related macular degeneration may be more than a "macular" condition but one that involves the entire retina. Future longitudinal ...
Radii of curvature of the major lens refractive surfaces--the external and nuclear boundaries--decrease linearly with increasing accommodation in all eyes that are capable of accommodation. The rates at which they change with accommodation are age dependent, decreasing steadily toward zero with ...
From an investigation of measurements of pupil size made on 222 subjects from 20 to 89 years of age it was concluded that there was a marked reduction in the size of the pupil with age in both light and dark conditions. The older pupil in proportion to initial size constricted as much as...
Combining multisensory sources is crucial to interact with our environment, especially for older people who are facing sensory declines. Here, we examined the influence of textured sounds on haptic exploration of artificial textures in healthy younger and older adults by combining a tactile device (ul...
