In many cases, blindness due to diabetic retinopathy can be prevented provided treatment with laser photocoagulation is used at the correct time. Studies were excluded if they evaluated changes in risk factors or cost-effectiveness only. Time from registration with the screening programme to first screening episode is strongly related to age at registration. The average HbA1c value was calculated for each patient for the previous 8 years to estimate long-term glycaemic control. Outcomes measured were referral rates, alteration of Snellen visual acuity, and the need for macular photocoagulation treatment. We thank the Cambridge University Hospitals NHS Foundation Trust Department of Clinical Biochemistry and the NIHR Cambridge Biomedical Research Centre, Core Biochemical Assay Laboratory for carrying out the biochemical assays and the following groups within the MRC Epidemiology Unit: data management (Adam Dickinson), IT (Iain Morrison), technical (Matt Simms) and field epidemiology (Paul Roberts). He pointed to a recent UK study which showed that 50% of patients who presented to one hospital’s ophthalmology service because of visual loss due to retinopathy had not had any form of prior screening.
Median interval referral to ophthalmological review was 11.5 weeks with 73% reviewed in under the 13-week target. You details will not be passed on to any other organisation without your permission. Richard Morrice, 43, experienced the benefits of the camera during a routine eye check in May 2009. We conclude that effective district-wide screening for diabetic retinopathy by optometrists using slit-lamp and Volk lenses is possible; however, only 36% of identified people with diabetes in the district were screened over a 4-year period.
