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

MRI study of the changes in crystalline lens shape with accommodation and ageing in humans [PDF]
, 2011 Magnetic Resonance Imaging was used to study changes in the crystalline lens and ciliary body with accommodation and aging. Monocular images were obtained in 15 young (19-29 years) and 15 older (60-70 years) emmetropes when viewing at far (6m) and at ...
