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.

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, 2007ABSTRACT Purpose. Convergence insufficiency (CI) is the most prevalent of binocular dysfunctions. A prime finding in the diagnosis of CI is the near point of convergence (NPC). Methods.

Convergence near a point and the Arzela-Ascoli-type theorems
Ukrainian Mathematical Journal, 1993In this note necessary and sufficient conditions for the convergence of a sequence of continuous (differentiable) functions to a continuous (differentiable) function are proved. Concepts of convergence near a point and equipotential convergence near a point are introduced.

Near point of convergence in high school athletes
2018Context: Awareness of sport-related concussions (SRC) has increased significantly in recent years. The clinical diagnosis of SRC is typically performed with tools assessing postural stability, cognitive function, neurocognitive, vestibular, and ocular motor deficits.

Receded near point of convergence and gait are associated after concussion
British Journal of Sports Medicine, 2017ObjectiveTo examine post-concussion gait among patients with and without receded near point of convergence (NPC) and uninjured controls.DesignProspective observational study.SettingRegional sport-concussion clinic.ParticipantsThirty-one patients presented 10.1 [95% CI=8.1, 12.1] days post-concussion (57% female, age=16.5 [15.4, 17.7]); 38 controls were

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.

The vergences fulfill the second of the two tasks assigned to the motor system of the eyes. They align the eyes in such a way as to ensure and maintain binocular fixation and binocular vision. Since, by definition, they are movements of the two eyes in opposite directions, they are also known as disjunctive movements.

Creating stereograms for near point of convergence exercises.
Journal of ophthalmic nursing & technology, 2000Pencil push-ups, for near point of convergence exercises, are a basic treatment for symptoms related to near work. Utilizing the computer to generate training stereograms increases the patient's interest and compliance with NPC exercises and assures a better treatment result.
