These functional changes have also been correlated with various age-associated structural changes. For example, aging causes loss of retinal neurons, including rod photoreceptors,27 RGCs28,29 and rod bipolar cells.30 Similarly, other non-neural cells, such as retinal pigment epithelium (RPE) cells...
Skin Aging AtlasMexican womenEye contourObjective: To evaluate the changes in certain ocular signs due to age, among Mexican women and to compare these with those previously obtained on women of other ethnicities. Material and methods: Photographs were taken of the faces of 203 Mexican women of ...
That causes changes or loss of your central vision over time. Wet: Abnormal blood vessels grow in your eye. They leak blood and fluid (shown here), which causes scars and further damages the macula. Both types leave you with a central blind spot. 14/32 Macular Degeneration: Test Cover ...
Compared with the other two types of age-related changes, posterior subcapsular changes are rather infrequent (Sasaki et al., 1987, 1989).TRUNCATED AT 250 WORDS) 展开 关键词:Aging Eye lens Human Electron microscopy DOI: 10.1016/0300-9629(95)00053-A ...

The method employs treating the eye with a long wave radiation beam in the UV-A range above the cornea absorption and/or in visible and/or close to the infrared wavelength range. This produces photoinduced, irreversible chemical changes ... HG Haensel 被引量: 18发表: 2001年 The eye lens:...
Changes in these schematic eyes with aging are increased anterior chamber depth, decreased lens thickness, increased vitreous chamber depth, increased axial length, and decreased lens equivalent power. Male schematic eyes have deeper anterior chamber depth, longer vitreous chamber depth, longer axial ...
The ability of sustained treatment of a single extraocular muscle with glial cell line-derived neurotrophic factor (GDNF) to produce a strabismus in infant non-human primates was tested. Six infant non-human primates received a pellet containing GDNF, re

In the higher animals, particularly the predatory species ofbirdsandmammals, binocular vision became more and more important. Structural changes in the placement of the eyes in the head permitted a larger overlap of ...
Secondary changes in the retina, probably resulting from a failure of optic axons to reach their central targets, were near total loss of ganglion cells and variable attenuation of the other nuclear and plexiform layers. Retinal rosettes were also commonly present. 展开 ...
