Procedure in ocular examination

Historical Significance: Arthur Marten Skeffington (1890 - 1976) was an American optometrist known to some as "the father of behavioral optometry". Skeffington has been credited as co-founding the Optometric Extension Program (OEP) with E.B. Alexander in 1928. In the mid-1950s, Skeffington first diagrammed his "four circles" model of describing visual processing. The OEP is a USA non-profit organization that began by providing elementary continuing education for optometrists in the 1920s when optometry was emerging from opticiancy. Later in the 1940s and 50s it embraced concepts, largely through Arthur M Skeffington, that that continue under the banners of behavioral optometry and vision therapy. The OEP had its origins in a continuing education program developed by the Oklahoma Optometric Association. E.B. Alexander was the secretary of the Oklahoma Extension Program.
