Robert Teeton, a 61-year old male, visited his ophthalmologist, Dr. Green, for his annual eye examination. Mr. Teeton’s chief complaint was decreased vision in the right eye for approximately 3 weeks. Upon examination by the physician, it was discovered that Mr. Teeton had a history of diabetic retinopathy. His medical history indicated that he has had insulin-dependent diabetes mellitus for 13 years, hypertension for 15 years, hypothyroidism, peptic ulcers, and cardiac arrhythmia. Dr. Green recommended a fluorescein angiogram to complete the diagnosis. The report from that procedure showed scattered microaneurysms in both eyes. Which of Mr. Teeton’s other conditions will increase the risk of diabetic retinopathy?
