UD researchers identify genes linked to cataract formation
(June18, 2015) When
cataracts encroach on the eyes, the only effective remedy is to surgically
replace the eyes' lenses with synthetic substitutes.
But what if scientists found a way to delay or prevent
cataracts from forming in the first place?
Researchers at the University of Delaware may have found
such an opportunity by identifying the prime suspects in the formation of
cataracts – deficiency of two genes that encode regulatory proteins.
When those two genes are unable to do their work, the lenses
of the eyes become cloudy and develop cataracts, no aging process or damaging
exposure to radiation required.
Cataracts, the leading cause of blindness, can have a
genetic basis.
