Term Description

Two 45 digital retinal images (Field 1 and 2) will be taken of each eye of the participant using the Canon Non-Mydriatic Retinal CR6-45NM camera with a digital Canon D60 camera back (6.3 megapixels per image). Field 1 is centered on the optic disc and Field 2 is centered on the macula, providing photographic documentation of the optic disc, macula, and substantial portions of the temporal arcades. These photographs may be graded for retinal microvascular characteristics, including focal arteriolar narrowing, arterio-venous nicking, retinopathy (e.g., microaneurysms, retinal hemorrhages) and other conditions. In addition, generalized arteriolar narrowing is quantified using a computer assisted measure of retinal vascular caliber. Training to take consistent gradable images is required although training is not extensive and quality of photography should be monitored throughout the entire study. Systematic grading of the images with adequate quality control procedures is imperative to minimize grader variability and to minimize misclassification leading to spurious or erroneous null findings. This protocol uses the Canon Non-Mydriatic Retinal CR6-45NM camera with a digital Canon D60 camera back (6.3 megapixels per image). Other ophthalmic imaging cameras can be used. If other instruments are used, the reproducibility of the measurements should be comparable to those acquired with this protocol. The Ocular Working Group recommends cameras that capture images that are 5 mega-pixels or larger for use in grading and vessel measurement protocols. When other instruments are used to capture digital retinal images, the manufacturer and model of equipment should be recorded. These other cameras may require some different steps than are described in this protocol. Investigators should follow the equipment manufacturer's instructions to ensure quality control. In addition, this protocol uses EyeQSL,software which is commercially available through Digital Healthcare Inc. The Ocular Working Group notes that other ophthalmic imaging packages are available through other vendors that are similar in nature. These other software packages may require some different steps than are described in this protocol. Investigators should follow the manufacture's instructions to ensure quality control. Please be sure to record the manufacturer and model and version of the software used.
