Vision therapy and adults with convegence insufficiency

"Patients should be referred to a behavioral [also known as a developmental optometrist] or neuro-optometrist. It was also noted that referrals made to an ophthalmologist may be insufficient, as they are primarily concerned with the health of the eye only, and ophthalmologists are mostly experienced with acute medical problems rather than rehabilitation issues."

Raymond, et al. Rehabilitation of visual processing deficits following brain injury.NeuroRehabilitation 6 (1996) 229-240.


"Today, a relatively small group of optometrists still practice and continue to perfect optometric vision therapy techniques.  Yet, it is difficult for a strabismic patient to learn about, much less access, this type of clinician."
