Effect of Repetitive Sub-concussive Head Impacts on Ocular Near Point of Convergence
International Journal of Sports Medicine, 2016This study intended to examine effects of repetitive sub-concussive head impacts on ocular near point of convergence (NPC). 20 healthy young adult soccer players were assigned to either a heading or control group. Heading subjects completed 10 headers of soccer balls projected at a speed of 11.2 m/s. Control subjects did not perform heading.

Comparing Patient- and Clinician-Administered Near Point of Convergence After Concussion
Journal of Sport Rehabilitation, 2021Objective: (1) To compare patient- and clinician-administered measurements of near point of convergence (NPC) distance including the percentage of patients exceeding clinical cutoffs among concussed adolescents and (2) to assess the reliability of patient- and clinician-measured NPC distances. Methods: A total of 762 patients (mean = 15.51, SD = 3.09 y)

Near Point of Convergence Norms Measured in Elementary School Children
Optometry and Vision Science, 2007Convergence insufficiency (CI) is the most prevalent of binocular dysfunctions. A prime finding in the diagnosis of CI is the near point of convergence (NPC).The NPC was measured six different times on the same 539 children, once in the fall and once in the spring, over the course of 3 years.

Effect of 3-Dimensional Central Stimuli on Near Point of Convergence
Strabismus, 2015Since an interaction between binocular disparity and the vergence system takes place in order to reduce retinal disparity, it is likely that vergence control, as measured with the near point of convergence (NPC), will be better if the target used for measurement has 3-dimensional (3-D) features in its most central parts.

To Investigate the Near Point of Convergence (NPC) in Hyperopic Children
2022Purpose: This study was aimed to investigate the Near point of Convergence (NPC) in hyperopic children. Methods: The subjects comprised of school-going 76 children aged 5-14 years. The NPC was measured with the help of Royal Air Force (RAF) ruler. Refractive error is defined based on the spherical equivalent (SE) of cycloplegic refraction.

Acute Effect of Caffeine on Amplitude of Accommodation and Near Point of Convergence
West African Journal of Pharmacology and Drug Research, 2008Caffeine is widely consumed in kola nuts and in other products in Sub-Saharan Africa. We examined the acute effect of caffeine on the amplitude of accommodation and near point of convergence of healthy Nigerians. Forty volunteers between ages of 20 and 27 years with refractive power± 0.50 DS were employed.
