Fundus photography can track changes in the eye over time in people who have diabetic retinopathy and especially in those who have been treated for it.Fundus photography produces accurate pictures of the back of the eye (the fundus).Even if you don't smoke, you might inhale secondhand smoke if you go where people are smoking or if you live with someone who smokes.
But survival rates are improving for many types of cancer, thanks to improvements in cancer screening and cancer treatment.
If cancer is common in your family, it's possible that mutations are being passed from one generation to the next.
You might be a candidate for genetic testing to see whether you have inherited mutations that might increase your risk of certain cancers.
An eye doctor can compare photographs taken at different times to watch the progression of the disease and find out how well treatment is working.
But the photos do not take the place of a full eye exam.(But women who develop gestational diabetes during pregnancy have a greater chance of developing type 2 diabetes later in life, which can put them at increased risk for retinopathy and other eye problems.) People who have diabetes are also at increased risk for other eye diseases, including glaucoma and cataracts.Regular dilated eye exams can help detect these diseases early and prevent or delay vision loss.Instead, you may need one or more other gene mutations to cause cancer.
