According to the new study that the number of Americans with major eye diseases is expected to increase drastically as more people are diagnosed with diabetes. The study suggests that vision loss is related to eye disease among people with diabetes which can lead to depression, reduced mobility and reduced quality of life. Among American adults, diabetic retinopathy is the leading cause of blindness. In 2004, more than $500 million was spent as medical costs for diabetic retinopathy. Diabetic patient are more likely to suffer from eye diseases such as cataracts and glaucoma than the general population. Researchers estimated that diabetic retinopathy cases from 2005 to 2050 will increase from 5.5 million to 16 million and vision-threatening diabetic retinopathy cases will rise from 1.2 million to 3.4 million. The researchers also said that cataract cases among whites and blacks aged 40 years and more with diabetes will likely rise 235 % and cataract cases among people with diabetes who are aged 75 years and more will increase 637% for black women and 677% for black men. The study suggests that efforts to prevent diabetes and to optimally manage diabetes and its complications are needed.
