![]() A key advantage of iris recognition, besides its speed of matching and its extreme resistance to False Matches, is the stability of the iris as an internal, protected, yet externally visible organ of the eye. Hundreds of millions of persons in countries around the world have been enrolled in iris recognition systems, for convenience purposes such as passport-free automated border-crossings, and some national ID systems based on this technology are being deployed. Databases of enrolled templates are searched by matcher engines at speeds measured in the millions of templates per second per (single-core) CPU, and with infinitesimally small False Match rates. Digital templates encoded from these iris scan patterns by mathematical and statistical algorithms allow unambiguous positive identification of an individual. Together you can determine what procedure or combination of procedures is best for you. Ask your ophthalmologist about the risks and benefits of your treatment options. Unlike retina scanning, and iris scan uses camera technology with subtle infrared illumination to acquire images of the detail-rich, intricate structures of the iris. Ultrasound Treatment Surgery is almost always used to repair a retinal tear, hole or detachment. Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of the irides of an individual’s eyes, whose complex random patterns are unique and can be seen from some distance. ![]() The larger the pupil, the more light can enter. In response to the amount of light entering the eye, muscles attached to the iris expand or contract the aperture at the center of the iris, known as the pupil. In some cases it can be hazel (a combination of light brown, green and gold), grey, violet, or even pink. ![]() “Eye color” is the color of the iris, which can be green, blue, or brown. The iris (plural: irides or irises) is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupils and thus the amount of light reaching the retina. Likewise, indications of chronic health conditions such as congestive heart failure, atherosclerosis, and cholesterol issues first appear in the eyes. Communicable illnesses such as AIDS, syphilis, malaria, chicken pox well as hereditary diseases like leukemia, lymphoma, and sickle cell anemia impact the eyes. It works by casting an unperceived beam of low-energy. Retinal scanning also has medical applications. Retinal scanning is based on the fine capillary network that provides oxygen and nutrients to the retina. The pattern of variations is converted to computer code and stored in a database. Because retinal blood vessels are more absorbent of this light than the rest of the eye, the amount of reflection varies during the scan. This beam of light traces a standardized path on the retina. A retinal scan is performed by casting an unperceived beam of low-energy infrared light into a person’s eye as they look through the scanner’s eyepiece. The blood vessels within the retina absorb light more readily than the surrounding tissue and are easily identified with appropriate lighting. The network of bloodvessels in the retina is so complex that even identical twins do not share a similar pattern.Īlthough retinal patterns may be altered in cases of diabetes, glaucoma or retinal degenerative disorders, the retina typically remains unchanged from birth until death.Ī biometric identifier known as a retinal scan is used to map the unique patterns of a person’s retina. Because of the complex structure of the capillaries that supply the retina with blood, each person’s retina is unique. ![]() Feel free to contact our office to inquire about an OCT at your next appointment.The human retina is a thin tissue composed of neuralcells that is located in the posterior portion of the eye. It is performed in about 10 minutes right in our office. These detailed images are revolutionizing early detection and treatment of eye conditions such as wet and dry age-related macular degeneration, Glaucoma, Retinal Detachment and Diabetic Retinopathy.Īn OCT scan is a noninvasive, painless test. With an OCT scan, doctors are provided with color-coded, cross-sectional images of the retina. It works using light without radiation, and is essential for early diagnosis of glaucoma, macular degeneration and diabetic retinal disease. Similar to ultrasound, this diagnostic technique employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye.Ī scanning laser used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to an CT scan of the eye.
