Abstract Details

Purpose:

To study clinical effectiveness of the modern 3D technology training program to enhance visual functions in patient with refractive and anisometropic amblyopia

Setting:

Pirogov Russian National Research Medical University (RNRMU), Moscow, Russia  Eye surgery center, Moscow, Russia

Methods:

The study included 37 patients (52 eyes) aged 8 to 36 years with refractive and anisometropic amblyopia. There were 30 patients (38 eyes) in group I and 7 patients  (14 eyes) who underwent LASIK in group II. The treatmen was carried out using interactive program in the condition of virtual occlusion and optical ametropia correction (I), and after 3 months after corneal surgery (II). Virtual occlusion was provided by using polarized 3D technique (passive 3D glasses and 3D monitor). All patients were trained for 30 minutes per day during 10 days. The training distance 50 cm.

Results:

There was a significant improvement in amblyopic eye acuity after training (BCVA before  0,22±0,27 (I group); 0.2±0.1 (II group) and after treatment 0,09±0,24( I group), 0.08±0.07 (II group)). There was improvement in binocular function (binocular vision before training in 17 patients (I group), 5 (II group) and after 27 (I group), 7 (II group). In addition, improvement in accommodation (before training PRA was 4.29± 1.5 D (I group) 2.64±1.54D (II group), after training - 5.33 ± 1.36 D (I group), 4±1.6 D (II group).

Conclusions:

Our study demonstrates that 3D technology virtual occlusion with “Poisk-2” software significantly improved visual outcomes (BCVA, binocular vision, volume of accommodation) in patients with refractive and anisometropic amblyopia. We consider promising the idea to use this program for visual rehabilitation before and after corneal refractive surgery.
