Article Synopsis
- - The study aimed to assess the safety and effectiveness of the Eidon white light 60-degree field Scanning Confocal Ophthalmoscope (SCO) camera for diabetic eye screening using staged mydriasis, involving a large trial with 1015 patients.
- - Results showed high sensitivity (97.5%) and specificity (82.3%) for detecting any retinopathy, indicating the camera's reliability, although some images remained unassessable even after dilation.
- - The researchers concluded that while the Eidon camera demonstrates promising performance, further studies are needed for diverse populations and to evaluate its cost-effectiveness.
Objective: This project was to determine the performance of the Zeiss Clarus 700 (Clarus) and the Optos California (Optos) with staged mydriasis in a Diabetic Eye Screening Programme (DESP).
Methods: Trial participants were recruited from people attending appointments in DESP or Virtual Eye clinics for delayed hospital appointments. Non-mydriatic photographs from the Clarus and Optos cameras were compared to 2-field 45 degrees mydriatic digital photography (the reference standard) and mydriatic photographs compared if the non-mydriatic photos were unassessable (staged mydriasis).
Aims: To investigate variables at the demographic and primary care practice levels that influence the uptake of diabetic retinopathy screening.
Methods: Data were extracted from the management software of one screening programme for 21 797 people registered with 79 general practices. Uptake was examined by gender, age group, modality of screening (mobile unit at general practice versus high-street optometrist), and by general practice.
Objectives: Diabetic Retinopathy screening services aim to reduce the risk of sight loss amongst patients with diabetes. The rising incidence of diabetes in England and the operational need to ensure the accuracy and timeliness of screening lists led to a pilot study of electronic extraction of data from primary care. This study aimed to evaluate the effectiveness of updating the single collated list of patients eligible for diabetic eye screening using extracts from electronic patient records in primary care.

This study was designed to investigate progression of diabetic retinopathy in this programme of the English NHS Diabetic Eye Screening Programme.
Methods: Mydriatic digital retinal photographs of people with diabetes screened on at least 2 occasions between 2005 and 2010 were graded and included in this study if the classification at first screening was no DR (R0), background DR in one (R1a) or both eyes (R1b).
