2017, Canadian Journal of OphthalmologyExcerpt from the Canadian Ophthalmological Society evidence-based clinical practice guidelines for the management of diabetic retinopathy
2017, Canadian Journal of OphthalmologyCitation Excerpt :Distance evaluation uses a teleophthalmology platform that tries to simulate, as closely as possible, clinical evaluation. It includes taking a history, obtaining visual acuity and intraocular pressure (IOP) measurement, stereoscopic photographs of the anterior segment, stereoscopic photographs of the disc and macula, and peripheral fundus photos.139 These teleophthalmology platforms generally utilize American Telemedicine Association Category 3 or 4 teleophthalmology systems.123,140
Risk factors for progression of diabetic retinopathy in Alberta First Nations communities
2017, Canadian Journal of OphthalmologyCitation Excerpt :Before stereoscopic, mydriatic retinal photography, intraocular pressure and visual acuity measurements were obtained. A modified Early Treatment Diabetic Retinopathy Study (ETDRS) protocol for imaging was used (with stereoscopic photographs of fields 1 and 2 only).12,13 Retinal photographs were uploaded onto a password-protected, two-factor, authenticated, secure web site and graded by ophthalmologists using a modified ETDRS grading algorithm.12,37,38

2012, Canadian Journal of OphthalmologyCitation Excerpt :Additionally, for every 10 mm Hg increase in average systolic blood pressure, the hazard of progression increased by 1.24 (95% CI, 1.06, 1.45; p = 0.009). There have only been a few studies assessing the prevalence of diabetic retinopathy in First Nations Canadians; a study in a remote northern Alberta community consisting mainly of First Nations participants identified DR in 47.1% of individuals, whereas PDR was present in 4.5% of patients.13 Similarly, a study from Southern Alberta found the prevalence of diabetic retinopathy among First Nations people with diabetes to be 40%, with many having advanced disease.41
Preliminary results of this study were presented as a poster paper at the Canadian Ophthalmological Society meeting held in Whistler, BC, June 17–20, 2000.
