Macular degeneration, diabetic retinopathy, retinopathy of prematurity, and retinitis pigmentosa can all be helped with a new technique called Retinal Image Translocation. RIT therapy was not possible until the introduction of high resolution digital fundus photography. Once the picture is viewed, the direction and the amount of prism can be determined.
Initially a person may report that things look blurred or go in and out of focus, but after a brief period of up to six weeks, the human brain learns to use a new piece of retina instead of the macula and vision improves.
New Hope for Vision Loss describes how RIT therapy works and how it can help patients with macular degeneration, in addition to retinal detachment, retinitis pigmentosa, and diabetic retinopathy.
