Answer:
Cataract
Explanation:
Cataract is a clouding of the eye’s lens and is the leading cause of blindness worldwide, and the leading cause of vision loss in the United States. Cataracts can occur at any age because of a variety of causes, and can be present at birth. Although treatment for the removal of cataract is widely available, access barriers such as insurance coverage, treatment costs, patient choice, or lack of awareness prevent many people from receiving the proper treatment.
An estimated 20.5 million (17.2%) Americans aged 40 years and older have cataract in one or both eyes, and 6.1 million (5.1%) have had their lens removed operatively. The total number of people who have cataracts is estimated to increase to 30.1 million by 2020.
Early treatment can potentially lead to better outcomes for these patients, which is why early testing is critical.3 If you or your child is experiencing early cataracts in both eyes, it is possible that the cause may actually be a rare, but treatable, genetic disorder. These cataracts may be the earliest and most common symptom of Cerebrotendinous Xanthomatosis (CTX), a lipid storage and metabolic disease.
In people with CTX, cholesterol doesn’t break down properly, causing cholestanols – toxins and bile alcohols – to build up in blood and tissues throughout the body.
When cholestanols build up in the tissue near the lens of the eye, they may lead to these cataracts. The cataracts may cause blurry vision and look like snowflakes or flecks in the eyes.
While these cataracts can and should be surgically removed, that will only resolve this one symptom of CTX. However, this disorder causes different symptoms in different people at different ages and can lead to serious health problems over time.
