Common Clinical Configuration of Zone of Zero‐Associated Phoria

Key Points

• To present common configurations of the zone of zero-associated phoria and their frequencies among asymptomatic patients.
• Clinical study involving 156 asymptomatic individuals.
• Identification of four common configurations of zone of zero-associated phoria.
• Collection of relative frequency data for each configuration.
• Four configurations identified as common in the studied population.
• Normative data established against which other patient populations can be compared.
• Relative frequencies of each configuration determined.
