Vitamin B12 for diabetic retinopathy.
Comment: This study suggests that diabetic retinopathy can be reversed (and presumably prevented) in a subset of patients with type 1 diabetes by administering daily injections of 100 [mu]g vitamin B12. While controlled trials are needed to confirm this report, vitamin B12 is safe and inexpensive, so it would be reasonable to administer it to children and teenagers with incipient hemorrhagic retinopathy whose disease started before age 10. In addition, it would be reasonable to administer vitamin B12 to patients with type 1 diabetes who do not have retinopathy, since vitamin B12 might prevent retinopathy from developing. This report was published more than a half-century ago, so a follow-up study is long overdue.
