I found this article because I was interested in the affect of Type II diabetes on vision, what it's caused by and how it can be treated. I didn't know much about the different types of eye complications such as glaucoma, cataracts and the different forms of retinopathy as stated in this article. I thought the different forms of retinopathy were interesting, because non proliferative doesn't require much treatment, but muscular edema requires successful treatment and proliferative retinopathy can be much more damaging. Proliferative takes many years to progress with a lot of damage to the blood vessels feeding the retina, which is why it's important to catch diabetic symptoms early on to prevent long term issues like this. My dad actually had a pre-diabetic episode which blurred his vision, but luckily enough it was caught so quickly that lifestyle changes were enough to reverse all the symptoms he acquired. However, although he is fine now, as are many other people, this may increase risk for future complications with not only eye sight, but other negative diabetic symptoms. Luckily we live in a world with great technology and medical treatments, but that's not enough to cure every diabetic issue. I thought the special laser used to burn the retina in order to seal newly formed blood vessels from growing was kind of scary, but really cool to see how damaging some things can help treat more important problems.
