Many vestibular and oculomotor symptoms are evident only when provoked by stimuli or movements. Convergence insufficiency training can assist the clinician decrease dizziness in their patients.

Vestibular rehabilitation and visual-oculomotor therapies involve an active, expose-recover approach to reduce impairment and symptoms. Initial results support the effectiveness of both vestibular and visual-oculomotor therapies, especially those that target specific impairments.

When it comes to intervening for ocular motor function, we know a couple of things very clearly.

 1.            We have no evidence that we will make any changes to smooth pursuit or saccades or VOR suppression by doing exercises that involve those three tasks. That has been clearly stated in such papers as Gallaway in 2017, Simpson-Jones in 2018, and Hall 2016 with The Clinical Practice Guidelines for Vestibular Function also talk about that.              

2.            We do not need to work on smooth pursuit exercises or saccadic eye movement exercises to improve those functions. If we have to do some of that as a habituation task, that can certainly be done in the short term. We are not going to improve somebody’s saccadic intrusions with smooth pursuit by doing smooth pursuit. There is no evidence that that works.

3.            Convergence insufficiency can be improved with training. In the clinic, we may use that as a habituation task if somebody is very dizzy with those tasks. Then accommodation is not insufficiency. It is also not something that we are going to treat routinely. However, if we know that somebody has trouble with accommodation, we can work on near, far shifting when doing functional tasks in the clinic.
