Fig A: Optose Daytona
Fig B: Wide Field Image from the Optose Daytona
The Optos Daytona was designed to assist eye care professionals to diagnose and manage diseases of the retina. It produces a 200 degree image of the retina, wide enough to image almost all of the retina, without the need for dilation.
The regular fundus camera produces an image of about 45 degrees, covering the important central area of the retina. Within this central area, the optic nerve, macular, arteries and veins can be observed carefully, helping to detect glaucoma, macular degeneration, hypertensive retinopathy, etc.
A wide area is however missed, notably, the peripheral retina where it is more likely to find retinal holes, retinal tears, retinal detachment, cancer, hemorrhages, other forms of degeneration, etc. Figure C shows the difference in retinal coverage between the two technologies. (the inner circle is taken with the regular fundus camera.)

For a small fee, this technology increases the chances of detecting retinal pathology early before symptoms occur. Early treatment means shorter, less expensive treatment, with a better visual outcome.
Eye care practitioners invest in new, state of the art technology so as to offer patients the best care possible.
Let your practitioner know if you would like this to be part of your next eye health exam.
