Is Dilation Necessary?
Ultra-widefield imaging devices have the capacisty to document peripheral retinal pathology, providing up to a 200-degree temporal and nasal imaging field and the ability to image up to 82% of the retina. However, retinal lesions located anterior to the equator are likely to be missed by doctors using UWFI alone. Researchers have determined this technology to have reduced sensitivity (36%) for the detection of the lesions compared with binocular indirect ophthalmoscopy using scleral indentation (76%). It was concluded that ultra-widefield imaging alone is not sufficient for making a clinical diagnosis.
Imaging devices such as OPTOS mapping are unable to allow examination of 20% of the surface of your retina. Of importance is the limited view of superior and inferior aspect which are where most detachments occur. Retinal detachments can cause vision loss if not treated right away.
Some offices are offering views of up to 200 degrees of your retina with ultra-widefield imaging, but that’s misleading and often more expensive for the patients.
Take the best care of your precious eyesight. Do not take the risk of undiagnosed disease to avoid a few hours of post eye dilation blurring.
