Mapping the Blind Spots of Vision

Harry Moss Traquair transformed how we detect disease by perfecting the science of perimetry. He realized that a patient’s peripheral vision often holds the key to diagnosing serious neurological and eye conditions.

Before his work, testing vision was often imprecise and lacked a standard clinical approach. Traquair developed a systematic way to map visual fields, which allowed doctors to pinpoint tumors and nerve damage by seeing where a patient could no longer see. His meticulous techniques became a cornerstone of modern ophthalmology worldwide. Even today, eye doctors continue to rely on the fundamental methods he pioneered to protect our sight.
