A Retinal Camera, or Wide-Field Imaging System, is used to capture detailed images of the retina, optic nerve, and blood vessels at the back of the eye. Compared to standard retinal cameras, wide-field systems provide a larger view of the retina in a single image. This helps detect conditions such as diabetic retinopathy, retinal detachment, glaucoma, and macular degeneration. The images can also be stored and compared over time to monitor disease progression. The system usually includes a digital camera, optical imaging lenses, illumination system, and computer software for image analysis.
