BACKGROUND The impact of bariatric surgery on diabetic retinopathy (DR) is unclear. DR might improve after surgery because of improvement in DR risk factors, but the rapid improvement in hyperglycemia after surgery could worsen DR. OBJECTIVES To assess the impact of bariatric surgery on the progression to sight-threatening DR (STDR) in patients with type(More)
RATIONALE Obstructive sleep apnea (OSA) is associated with several pathophysiological deficits found in diabetic retinopathy (DR). Hence, it's plausible that OSA could play a role in the pathogenesis of sight-threatening DR (STDR). OBJECTIVES To assess the relationship between OSA and DR in patients with type 2 diabetes and to assess whether OSA is(More)
PurposeTo evaluate the effectiveness of digital diabetic retinopathy screening in patients aged 90 years and over.MethodsThis is a retrospective analysis of 200 randomly selected patients eligible for diabetic retinopathy screening aged 90 years and over within the Birmingham, Solihull, and Black Country Screening Programme.ResultsOne hundred and(More)
OBJECTIVES To determine the best photographic surrogate markers for detecting sight-threatening macular oedema (MO) in people with diabetes attending UK national screening programmes. DESIGN A multicentre, prospective, observational cohort study of 3170 patients with photographic signs of diabetic retinopathy visible within the macular region [exudates(More)
AIMS To assess the efficacy and value of the National Institute for Health and Clinical Excellence guidelines for digital photographic screening for diabetic retinopathy in pregnancy using photographic review clinics. METHODS Pregnant patients (n = 186) with known diabetes were screened at first antenatal visit and at 28 weeks' gestation, if no(More)
AimTo assess whether the current starting age of 12 is suitable for diabetic retinopathy (DR) screening and whether diabetes duration should be taken into account when deciding at what age to start screening patients.Materials and methodsA retrospective analysis of 143 patients aged 12 years or younger who attended diabetic eye screening for the first time(More)
BACKGROUND/AIMS Retinal screening programmes in England and Scotland have similar photographic grading schemes for background (non-proliferative) and proliferative diabetic retinopathy, but diverge over maculopathy. We looked for the most cost-effective method of identifying diabetic macular oedema from retinal photographs including the role of automated(More)
