The Zhang Ring Test™ was designed by Dr. Fuxiang Zhang, MD in conjunction with the Henry Ford Health System as very effective tool for patient self-detection and emergency medicine providers for a screening test to promote early diagnosis of retinal detachment.
Retinal detachment (RD) is a potentially devastating blinding disease and the prognosis is mainly determined by how soon it is diagnosed and managed surgically. There is a need to have surveillance in high-risk patients. A home used device to monitor retinal detachment is helpful as Ocular emergency cases are quite common with floaters, flashes of light, with or without peripheral vision or central vision decrease, however The Zhang Ring Test™ provides an easy to use screening test in emergency medicine, urgent care, patient home and other settings in this regard. Each SKU 9103 consists of a Pad of 50 tests with instructions printed directly on the test.
