OBJECTIVE: Women who have gestational diabetes mellitus (GDM) have elevated lifetime risks for the development of type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD), compared with their peers. However, it is not known whether their risk of CVD is dependent upon the development of T2DM. Thus, we sought to evaluate the role of T2DM in determining vascular outcomes in women with previous GDM. RESEARCH DESIGN AND METHODS: All women in Ontario, Canada, with a live-birth pregnancy between April 1994 and March 2014 (n = 1,515,079) were stratified into the following four groups: women with GDM in whom T2DM subsequently developed (n = 15,585, median age 32 years); those with GDM in whom T2DM did not develop (n = 41,299; median age 32 years); women who did not have GDM but in whom T2DM developed (n = 49,397; median age 31 years); and those with neither GDM nor T2DM (n = 1,408,798; median age 30 years)...

We were challenged and delighted when Dr. Sharon Solomon, guest editor of this Retina Supplement, invited us to reminisce about caring for patients with common retinal disorders before there was access to the diagnostic and therapeutic tools that are readily available today. We agreed to confine our remarks to 3 common, but serious, conditions: age-related macular degeneration (Dr. Fine), diabetic retinopathy (Dr. Goldberg), and retinal detachment (Dr. Tasman). Each of us completed our ophthalmology training about half a century ago...
