• Retina/Vitreous

    This 25-year population-based study of individuals with type I diabetes taking insulin indicates that relatively high incidence rates (29 percent) of macular edema and clinically significant macular edema (17 percent) are related to glycemia, systolic and diastolic blood pressure, and nephropathy as manifest by gross proteinuria. The lower incident macular edema rate during the last period of follow-up may reflect recent improvement in care.
