Historical Significance: Pleoptics is an alternative system of methods for the treatment of amblyopia and eccentric fixation. It was devised in 1947 by Alfred Bangeter (1909-2002), a Swiss ophthalmologist who was head of the Eye Department in St-Gallen from 1946 to 1983. He actively promoted his methods at conferences, in publications and through a School of Pleoptics and Orthoptics that he created. The method used bright light to desensitise the region of the retina used for eccentric fixation and the stimulation of the true fovea with flashing lights. and other methods. Bangeter devised some 20 instruments for providing pleoptic treatment. His contemporary, Curt Cuppers, (1910-1995), a German ophthalmologist, was equally inventive in producing instruments, of which this item is one example. However, pleoptics did not hold to its initial promise and interest in it declined during the 1960s. See Priestley BS. Pleoptics instruments and methods. Int Opthal Clinics 1961; 1: 787-827 for a detailed account of pleoptic instruments.
