1 Diabetes may be first diagnosed when there are large changes in spectacle correction causing blurriness. It is due to the effect of blood sugar changes on the lens of the eye.

2 Diabetes is one of the common causes of III, IV, and VI cranial nerve paralysis. It is due to the closure of brainstem vessels. The resulting diplopia may be the first symptom of diabetes and often resolves by 10 weeks.

3 Retinopathy due to microvascular disease (see front and back cover) may result in macular edema. It is the primary reason for blindness before age 65. Patients with diabetes should have annual eye exams, because early treatment is critical. Retinopathy is rare in children before age 15.
