Practical orthopics in the treatment of squint

Historical Significance: This is a second edition of one of the classic text books in orthoptics. The 'greats' in orthoptics were Claude Worth (1869-1936) who wrote 'Squint, its causes, pathology and treatment' (First edition 1903, 6 later editions) and Francis Bernard Chavasse (1888-1941). Chavasse wrote a 7th edition (1939) of Worth's book, which became 'Worth and Chavass's Squint: the binocular reflexes and the treatment of strabismus' in later editions. Keith Lyle wrote the 8th edition of this book (1950) and a 9th, with GJO Bridgman, published in 1959. Worth founded the orthoptic clinic at Moorfields Eye Hospital and invented the amblyoscope (synoptophore). T Keith Lyle CBE MA MD MChir FRCP FRCS (1905-1987) was an international figure in ocular motility who in addition to wirting this book edited Chavasse's edition of Worth's squint and the 13th Ed of May and Worth's diseases of the eye.
