Special attention is given to quantitative techniques for analysis of fundus photographs with a focus on clinically relevant assessment of retinal vasculature, identification of retinal lesions, assessment of optic nerve head (ONH) shape, building retinal atlases, and to automated methods for population screening for retinal diseases. Methods for 2-D fundus imaging and techniques for 3-D optical coherence tomography (OCT) imaging are reviewed. Following a brief overview of the most prevalent causes of blindness in the industrialized world that includes age-related macular degeneration, diabetic retinopathy, and glaucoma, the review is devoted to retinal imaging and image analysis methods and their clinical implications. While a number of other anatomical structures contribute to the process of vision, this review focuses on retinal imaging and image analysis.

These drops also cause blurring of the vision for a few hours. The digital retinal imaging is a quick process as the retinal imaging machine takes only a few seconds to capture images of the retina.Īs the process only involves capturing a digital image of the eye, there is no pain or discomfort.ĭilation is a process where your eye doctor will place some eye drops to dilate your eyes so that he can visualize your retina with a magnifying glass and bright light. If you are wondering is retinal imaging necessary, here are some ways this eye exam can benefit you: This exam gives a clearer and precise digital image of the retina for your physician to examine. In a digital retinal imaging eye exam, a picture of the back of your eye is taken which helps to visualize the health of the retina, surrounding structures, and blood vessels. If you have any conditions like diabetes or you are passing your 50s and 60s, your eye doctor will recommend a digital retinal imaging eye exam.
