Giffard P, et al. – The physicians conducted this work to determine repeatability and reliability of near point convergence (NPC) in neutral and torsion and compare between idiopathic neck pain (NP) and controls along with correlation to the Convergence Insufficiency Symptom Survey (CISS). It was noted that NPC is impaired in neck torsion compared to neutral in NP supporting a cervical afferent cause. NPC, measured applying the RAF Rule, is a reliable and repeatable measure and can be applied to evaluate NPC and CI in those with NP. Objective rather than self–reported measures should be applied to examine CI in NP.
