Three Cases of Amblyopia With Fusion Maldevelopment Nystagmus Successfully Treated With Dichoptic Treatment.

We present three cases where traditional occlusion therapy with an eye patch proved ineffective for treating amblyopia associated with fusion maldevelopment nystagmus. In these cases, we transitioned to dichoptic therapy using the Occlu-pad, achieving successful outcomes. Eye patch occlusion of the sound eye consistently exacerbated nystagmus, whereas dichoptic treatment did not. Visual acuity improved to 0 (logMAR) in all cases following dichoptic therapy. This approach demonstrates the effectiveness of dichoptic treatment for managing amblyopia in patients with fusion maldevelopment and nystagmus.
