The literature on the use of biofeedback techniques in the treatment of visual and ophthalmologic disorders is reviewed. Although this consists mainly of case studies, there is mounting evidence that biofeedback may be applicable to the treatment of strabismus, nystagmus, blepharospasm, elevated intraocular pressure, and myopia. because of the success in applying biofeedback techniques in the treatment of other neuromuscular disorders, it is concluded that the use of these techniques in the treatment of blepharospasm and strabismus shows the most promise.
