Biofeedback in Idiopathic Infantile Nystagmus Syndrome

Low Vision in Children

Active eye movement control training, an old and still most prevalent intervention in low vision rehabilitation (LVR) was never used in nystagmus clinically.

Biofeedback training (BT) is the latest and newest technique for oculomotor control training in cases with low vision when using available modules in the new microperimetry instruments. Laboratory studies in the literature highlighted positive benefits from using BT in nystagmus cases. The purpose of this study is to assess systematically the impact of BT in a series of cases with Infantile Idiopathic Nystagmus (IIN) and formulate guidelines for further use of this intervention in nystagmus cases in general.
