The relationship between binocular vision symptoms and near point of convergence

The relationship between binocular vision symptoms and near point of convergence

.....a cutoff point of 9.5 cm correlated with the presence of symptoms with the testing procedures used in this study. ...The determination of NPC is helpful in the differentiation of symptomatic from asymptomatic subjects......

Comments: It is interesting that it has become harder and harder to get my primary colleagues to do a NPC on all there patients during a primary care evaluation. Time and again the NPC has been shown to be important in the determination of the presence of convergence insufficiency. I would also recommend that when you do a NPC that you use the red light method...which is very sensitive for the presence of convergence insufficiency. DM
