Irish National Diabetic RetinaScreen Programme: report on five rounds of retinopathy screening and screen-positive referrals. (INDEAR study report no. 1)

Abstract

ObjectiveTo study the uptake of annual diabetic retinopathy screening and study the 5-year trends in the detection of screen-positive diabetic retinopathy and non-diabetes-related eye disease in a cohort of annually screened individuals.DesignRetrospective retinopathy screening attendance and retinopathy grading analysis.SettingCommunity-based retinopathy screening centres for the Diabetic RetinaScreen Programme.Participants171 557 were identified by the screening programme to be eligible for annual diabetic retinopathy screening. 120 048 individuals over the age of 12 consented to and attended at least one screening appointment between February 2013 to December 2018.Main Outcome MeasuresDetection rate per 100 000 of any retinopathy, screen-positive referrable retinopathy and nondiabetic eye disease.ResultsUptake of screening had reached 67.2% in the fifth round of screening. Detection rate of screen-positive retinopathy reduced from 13 229 to 4237 per 100 000 screened over five rounds. Detection of proliferative disease had reduced from 2898 to 713 per 100 000 screened. Non-diabetic eye disease detection and referral to treatment centres increased almost eightfold from 393 in round 1 to 3225 per 100 000 screened. The majority of individuals referred to treatment centres for ophthalmologist assessment are over the age of 50 years.ConclusionsScreening programme has seen a reduced detection rate both screen-positive retinopathy referral in Ireland over five rounds of screening. Management of nondiabetic eye diseases poses a significant challenge in improving visual outcomes of people living with diabetes in Ireland.

Automated multidimensional deep learning platform for referable diabetic retinopathy detection: a multicentre, retrospective study

“…The ICDRSS is based on the clinical fundus examination of each quadrant 22. However, only one or two 45° fields of retinal images were taken for DR grading during the DR screening programme 12 15 25 26. This would lead to inaccurate classification of DR or confuse the graders when the grading is based only on one or two fundus photos.…”

Diabetic retinopathy screening in the emerging era of artificial intelligence

“…Iceland was among the first, with a national programme established as far back as 1980 [37]. Since then, some other European countries, including Denmark, Finland, Ireland and Sweden, have introduced national programmes [25,38,39], and some have partially launched or are on the brink of implementing programmes [39]. In Asia, national guidelines on diabetic retinopathy screening are available for 11 of 50 countries, but less than half of the population is covered and full details of screening programmes have been presented for only two countries [40].…”

A micro costing analysis of the development of a primary care intervention to improve the uptake of diabetic retinopathy screening

“…DRS has also been shown to be costeffective [23]. However, the success of screening programmes depends on continued high levels of attendance and rates are suboptimal in many countries [24][25][26]; hence, there has been interest in developing and testing of interventions to improve attendance at diabetic retinopathy screening [27]. While IDEAs was a funded research study, the total value of the award was not based on FEC.…”
