Harry Moss Traquair (1875-1954), Scottish ophthalmologist and perimetrist.

Harry Moss Traquair (1875-1954) was an Edinburgh Ophthalmologist, who was especially involved in the studies of perimetry and neuro-ophthalmology. In his monumental work, An Introduction to Clinical Perimetry, which for years was the standard textbook of perimetry, he included the description of the visual field as "an island of vision or hill of vision surrounded by a sea of blindness". His name continues to be recalled in the use of the term "Traquair Junctional Scotoma". In this history of Ophthalmology research, Traquair's life and work, including his major achievements, are discussed.
