Historical Significance: A synoptophore is for the diagnosis and treatment of strabismus and other binocular vision disorders. This instrument represent the zenith of synoptophore development. The first instrument using the principles of the synoptophore was the Priesley-Smith amblyoscope of 1896 that was developed further by Claud Worth in 1902 (See Cat Nos. 1130 and 1796). Mary Maddox, the first orthoptist, developed the kinetic stereoscope for a similar purpose in the 1930s. (See Cat Nos. 1554, 1555). See Cat No. 2415 for a 1930s version of the synoptophore that was the precursor of this 1960s one. See Cat No. 1875 for a brochure describing the range of synoptophores made by Clement Clark Ltd in the 1960s. Elaborate synoptophores fell from favour in the 1980s when some of the treatments it could deliver were shown to be of limited value and simpler tests and treatment devices that could be used for home treatment took their place.
