The expected findings for a near point of convergence (NPC) test are a break value of 5 cm and a recovery value of 7 cm. Which option matches this?

• A. 5 cm break, 7 cm recovery
• B. 7 cm break, 5 cm recovery
• C. 4 cm break, 6 cm recovery
• D. 6 cm break, 8 cm recovery

Answer: (A)

Near point of convergence tests assess how closely the eyes can converge to maintain binocular single vision as a target moves toward and then away from the nose. The break value is where single vision is lost (diplopia) as the target approaches, and the recovery value is where single vision returns as the target moves outward. In typical measurements, the recovery distance is farther out than the break distance, meaning you see break at a closer point and recovery a bit farther away. The stated expectation of a break at 5 cm and a recovery at 7 cm fits this pattern, so the option listing 5 cm break and 7 cm recovery is the correct match. Other options assign different break/recovery distances or reverse the relationship, which does not align with the given expectation.
