Eccentric viewing training.

Eccentric viewing training seeks to train subjects to utilize a paramacular area of the retina for seeing when the macular area is damaged. The present paper demonstrates two techniques for training eccentric viewing, as well as a method for measuring impovement in the use of the paramacular area. Both techniques are inexpensive, can be administered by a technician, and do not require an extensive training period. However, there are indications the two techniques are not comparable in effectiveness.
