Patients with Type I diabetes, "juvenile diabetes," are often subject to retinal complications such as diabetic retinopathy. In an early study, about 1/2 of 15 patients with type I diabetic retinopathy who received vitamin B12 at the same time as they took their daily insulin shot experienced complete recovery from signs of retinal problems after 12 months.
