amblyopia

Amblyopia, commonly known as "lazy eye," occurs when the brain's visual cortex, during the critical developmental period (usually before age 8), actively suppresses signals from the weaker eye due to imbalanced input from the two eyes, causing reduced vision in that eye and impaired stereo vision.

Traditional patching therapy forces the brain to use the weaker eye by covering the dominant eye, but adherence has long been a clinical challenge, with studies showing that children's actual patching time is often far below the prescribed requirement.

Amblyopia affects about 3% of the world's population.

Patching therapy is the first-line amblyopia treatment supported by evidence-based medicine, but poor compliance is a recognized problem, and children's actual patching time is often far below the prescribed requirement.

Amblyopia is a neurological problem in which the brain actively suppresses the input signal from one eye.

The classic amblyopia treatment is patching the dominant eye to force the amblyopic eye to work, but compliance is extremely poor.

Dichoptic training is an amblyopia treatment method that forces the brain to integrate information from two channels by presenting different images to the left and right eyes respectively.

Research shows that dichoptic training can improve visual acuity and stereoacuity in the amblyopic eye, and because it is more engaging, patient compliance improves significantly.
