Lens aging: Effects of crystallins [PDF]

Biochimica et Biophysica Acta (BBA) - General Subjects, 2009
The primary function of the eye lens is to focus light on the retina. The major proteins in the lens--alpha, beta, and gamma-crystallins--are constantly subjected to age-related changes such as oxidation, deamidation, truncation, glycation, and methylation. Such age-related modifications are cumulative and affect crystallin structure and function. With

THE DISAPPEARANCE OF OPACITIES OF THE CRYSTALLINE LENS. [PDF]

JAMA: The Journal of the American Medical Association, 1902
SPONTANEOUS DISAPPEARANCE OF SENILE CATARACT. In 1900 I reported13an interesting case of this nature in a man of 73, who had marked senile changes in his circulatory system as well as prominent muscular and nervous symptoms. Several months before his first visit to me he had an attack, which was at first diagnosed as apoplexy, but later was judged ...

Age-related changes of the human ciliary muscle. A quantitative morphometric study [PDF]

, 1992
The age-related changes of the ciliary muscle of human eyes (33-87 years) were studied on histological meridional sections. Eighty-five melanoma eyes and 10 eyes of normal donors were investigated. The total area and the length of the muscle, the area of
