In brief: Possibly

Floaters are usually a natural condition that occurs as the gel that fills the back of the eye forms cracks over time.
High blood sugar can lead to damage, abnormal blood vessel growth, and breaks in the small blood vessels in the back of the eye, which can in turn cause bleeding in the eye. You may experience this as floaters. An eye doctor can quickly determine the cause of your floaters.

In brief: Yes

Uncontrolled blood sugar over an extended period of time, particularly with high blood pressure, can lead to blood vessel damage and subsequent diabetic retinopathy.
In proliferative diabetic retinopathy new blood vessels grow in response. However, these new blood vessels are abnormal and can break and bleed easily. Such bleeding can result in floaters and decreased vision.
