WebAbstract. The pathogenesis of cataract has been found to be influenced by number of factors including protein glycation. Cataract is the clouding or opacity that develops in the lens of eye. It forms when bounding or folding of protein changes and clump together; eventually these clumps cloud the lens and block the light. WebAbstract. At first sight, the lens of the eye would appear to be an ideal environment for amyloid fibril formation. The protein concentration is the highest of any tissue in the body, the proteins are very long-lived, present in slightly acidic conditions and subjected over time to extensive truncation and post-translational modification.
