Abstract Details


To study the influence of the modern 3D technology training program on the vision functions in refractive amblyopia patients.


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


There were 15 patients (19 eyes) aged 8 to 29 years (mean age 16,3) with refractive amblyopia of varying degrees. The treatmen was carried out using interactive program in the condition of virtual occlusion and optimal optical ametropia correction. 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 main principle of this game is to search for an identical to sample object. The training distance 50 cm.


There was a significant improvement in amblyopic eye acuity after training (BCVA before and after treatment - 0.67 ± 0.2 and 0.87 ± 0.2). There was improvement in binocular function (binocular vision before (4 patients) and after (13 patients) training). In addition, improvement in accomodation (before training, the average value was 4.58 ± 1.3 diopters, after training - 6.12 ± 1.6 diopters).


Our results demonstrate that using a computer program, baced on 3D technology significantly improved visual functions in patients with refractive amblyopia. This separation of images rapidly improved the monocular vision acuty of the amblyopic eye with the reduction of supression and strengthen the binocular function and accomodation. We consider promising the idea to use this program for visual rehabilitation after corneal refractive surgery.
