Comparison of Nondiabetic Retinal Findings Identified With Nonmydriatic Fundus Photography vs Ultrawide Field Imaging in an Ocular Telehealth Program [PDF]

JAMA Ophthalmology, 2016
Ultrawide field imaging (UWFI) is increasingly being used in teleophthalmology settings. Given the greater area of the retina imaged, we evaluated the ability of UWFI vs nonmydriatic fundus photography (NMFP) to detect nondiabetic retinal findings in a teleophthalmology program.We conducted a retrospective single-center comparative cohort study from ...

Assessment of Correlation Between Diabetic Retinopathy and Metabolic Biomarkers Using Artificial Intelligence. [PDF]

J Diabetes Res
Background One of the main causes of blindness in the world, diabetic retinopathy (DR) is a dangerous condition that impairs vision in diabetics. Preventing visual loss requires early recognition of DR and prompt treatments. Artificial intelligence (AI) software combined with nonmydriatic fundus cameras has demonstrated encouraging gains in DR ...

Comparison of Widefield Laser Ophthalmoscopy and ETDRS Retinal Area for Diabetic Retinopathy

Ophthalmology Science, 2022
Purpose: To evaluate agreement of nonmydriatic confocal scanning laser ophthalmoscopy (SLO; EIDON [CenterVue]) and the 7-standard field ETDRS area on ultrawide-field (UWF) SLO imaging for identification of diabetic retinopathy (DR) severity.

Nonmydriatic fluorescence-based quantitative imaging of human macular pigment distributions [PDF]

Journal of the Optical Society of America A, 2006
We have developed a CCD-camera-based nonmydriatic instrument that detects fluorescence from retinal lipofuscin chromophores ("autofluorescence") as a means to indirectly quantify and spatially image the distribution of macular pigment (MP). The lipofuscin fluorescence intensity is reduced at all retinal locations containing MP, since MP has a competing

The Sensitivity and Specificity of Nonmydriatic Digital Stereoscopic Retinal Imaging in Detecting Diabetic Retinopathy [PDF]

Diabetes Care, 2006
OBJECTIVE—The objective of this study was to determine the sensitivity and specificity of Joslin Vision Network nonmydriatic digital stereoscopic retinal imaging (NMDSRI) as a screening tool in detecting diabetic retinopathy. RESEARCH DESIGN AND METHODS—We reviewed the records of 244 patients with diabetes who had a dilated funduscopic ...

The Association Between Vitamin D Deficiency and Nondiabetic Retinopathy in the American Population: National Health and Nutrition Examination Survey 2005-2008. [PDF]

Biomed Res Int
Objectives: Retinopathy is a vascular endothelial injury disease that can occur in individuals without diabetes. The prevalence rates of nondiabetic retinopathy (NDR) vary from 6% to 13.6% among individuals. Vitamin D deficiency (VDD) is common worldwide, and studies indicate that the overall prevalence rate of VDD in US adults is 41.6%. Ample evidence

Diabetic Retinopathy Screening Ratio Is Improved When Using a Digital, Nonmydriatic Fundus Camera Onsite in a Diabetes Outpatient Clinic

Journal of Diabetes Research, 2016
Objective. To evaluate the effect of onsite screening with a nonmydriatic, digital fundus camera for diabetic retinopathy (DR) at a diabetes outpatient clinic. Research Design and Methods. This cross-sectional study included 502 patients, 112 with type 1
