Myopia Reduction with Biofeedback Training of Accommodation, Joseph N. Trachtman, O.D., Ph.D., Scott M. Pelcyger, O.D., Catherine M. Venezia, A.C.S.W. Journal of Behavioral Optometry, Volume 10, Number 4, p. 87-93, 1999
Abstract
We present data on 1,334 patients who received vision
training using a regimen based in the biofeedback control of accommodation for
myopia reduction. These patients were treated in 21 private optometric
practices, one private ophthalmological practice, one hospital ophthalmology
clinic, 15 vision training centers, and one ophthalmologic clinic center.
Patients ranged in age from 7 to 62 years with an average age of 24 years, and
were from the United States, Singapore, Israel, and Italy. Each patient
received a clinical treatment program, whereby, reductions in myopia were
occasioned with 0.5 Diopter reductions in the habitual spectacle correction.
The results showed a median 1.00 Diopter reduction in myopia after an average of
19 training sessions, with an average improvement in uncorrected visual acuity
from 20/170 and 20/32. Accommodative relaxation appears to be related to the
Alpha wave component of the electroencephalogram. Future research into myopia
treatment should investigate further the relationship between myopia and brain
function in general, and accommodative function and the Alpha brain wave, more
specifically.
