PAC 2 is indicated when both the objective and subjective angles are exotropia with the subjective angle greater. Which option corresponds?

• A. PAC 2
• B. PAC 1
• C. HAC
• D. Unharmonious correspondence

Answer: (A)

Pattern of anomalous correspondence describes how the brain’s perceptual map lines up with the motor alignment measured during testing. Here, you’re looking at both objective and subjective angles in exotropia. The objective angle comes from the motor measurement (prism cover test), while the subjective angle comes from the patient’s perception of alignment during sensory testing. When both show exotropia, but the subjective angle is larger than the objective angle, that specific relationship is labeled as PAC 2. This indicates the sensory system has adapted to a greater misalignment than what the motor test reveals, reflecting a particular pattern of sensory-motor adaptation. The scenario described matches PAC 2.
