简要总结

This study involves the collection ocular lens tissue from individuals with Down syndrome and age-matched controls at the time of cataract surgery.

详细描述

Individuals with Down syndrome have an increased rate of cataract. The reason for this increase is unclear. Normally, once cataracts become a significant impairment, an ophthalmologist will determine when cataract surgery should be performed. When this surgery is performed, cataractous tissues are cut out and discarded with medical waste. In this study, these tissue will be collected and protein analysis performed to determine what changes in different proteins are found in Down syndrome lenses as compared to normal cataractous lenses.
