Diabetes Mellitus Clinical Trial
Official title:
Comparison of Ultra-Widefield Scanning Laser Ophthalmoscopy and Two-Field Fundus Photography for Evaluating Diabetic Retinopathy
This study aims to compare the accuracy of evaluating diabetic retinopathy using ultra-widefield fundus images versus two-field fundus images. The hypothesis is that screening and grading diabetic retinopathy based on ultra-widefield fundus images may yield higher accuracy compared to the use of two-field fundus images.
As of 2030,9.7% (108.4 million) people in the China population have diabetes, and the total costs of diabetes in adults would reach $460.4 billion. Diabetic retinopathy (DR) and diabetic macular oedema (DME) are the principal causes of adult vision loss. Nevertheless,DR has few visual symptoms until DME occurs or the lessions located in the peripheral retina.Thus,it is crucial to early diagnosis and treatment of DR patients,which will prevent vision loss and reduce the societal buren of diabetes. The Early Treatment Diabetic Retinopathy Study (ETDRS) standard 7-field 30° color fundus photography is a time-consuming examination requiring pharmacological pupil dilation,experienced photographers and image montage.To simplify the operation process and improve patient compliance,2-field 45° retinal photographs (1 macular-centered field and 1 disc-centerde field) was proposed in the EURODIAB IDDM complications study and widely used in DR screening.Two-field 45° retinal photographs has been proven beneficial in reducing blindness resulting from DR,while may be neglected DR pathology in the peripheral retina.With the development of imaging technology, nonmydriatic ultra-widefield scanning laser opthoalmascopy (optomap) can obtain high-resolution,widefield images (180-200°) of the retina in only 0.25s. Optomap had good agreement with 7-field ETDRS in determining DR and DME severity and may be profitable in DR evaluation in research and clinical settings,espesially in predominantly peripheral lession(PPL). Patients with DM, with or without known DR, will be imaged using the optomap and 2-field 45° retinal photographs imaging device both for diagnosis and screening purposes at Ningbo Eye Hospital. Internal validation and continuous quality control will routinely be conducted. According to the International Clinical Diabetic Retinopathy Disease Severity Scale, the data for the ungradable image rate, distribution of DR severity levels, and PPL will be evaluated and compared. Statistics analysis will explore the agreement of DR severity levels between optomap images and 2-field photographs. ;
