Binocular vision and the modern treatment of squint

Historical Significance: The book discusses binocular vision, binocular balance, the suspension of vision, amblyopia, the refractor and the dynamic retinoscope, the use of the dynamic retinoscope in cases of squint, and orthoptic training. Margaret Dobson was medically qualified but an early proponent of non-surgical treatment of squint. See for example Margaret Dobson 'Notes on the non-operative treatment of squint 'Trans. Opt. Soc. 1923 ; 24: 101-102; her book 'Binocular imbalance' Lond OUP 1943; 'The amblyopia reader : a system of eye-sight development' 1935; 'Simple aids for the cure of very young squinters'1950; 'Dynamic retinoscopy' 1931; 'Anaglyphs : (their use in orthoptic training)' 1937. She is described on the title page as 'Ophthalmic surgeon to the Sussex Hospitial for Women and Children Brighton and Oculist in Charge of the Kilburn LCC Eye Clinic. See also cat No 548.
