The relationship between binocular vision symptoms and near point of convergence
...Due to the relatively high prevalence of binocular vision anomalies, a
regular examination including tests for assessment and determination of
these anomalies is necessary. .... The determination of NPC is helpful in the differentiation of symptomatic from asymptomatic subjects.....
Comments: The near point of convergence test (hopefully with a redlens and transiluminator light) should be routinely done on all of your patients. No ifs, buts, or any other excuses can suggest otherwise! DM
