Накратко на български

Детската амблиопия („мързеливо око“) се изследва чрез връзката между зрението, вниманието и координацията ръка-око при изпълнение на задачи в 3D среда. Това помага за подобряване на рехабилитацията, тъй като затрудненото триизмерно виждане пречи на ежедневието, например при шофиране или спорт.

Optimizing Vision reHABilition with virtual-reality games in paediatric amblyopia

Paediatric amblyopia (lazy eye) is a common, developmental vision disorder in children, causing a vision loss in one eye. Typical treatment for paediatric amblyopia is based on forcing the use of the bad eye to obtain a clear retinal image in each eye. But several aspects of paediatric amblyopia, like the involvement of 3D vision and motor function, are still understudied and not integrated in the rehabilitation process. The EU-funded V-HAB project conducted a deep investigation into vision-related sciences with emphasis on the role of motor control as well as selective attention in paediatric amblyopia. Whilst the main diagnosis for pediatric amblyopia was visual acuity (e.g., being able to see the letters in a Snellen chart), 3-dimensional vision may remain problematic, hampering people to drive cars or to play sports. With this project, we aimed to include this important vision skill in the treatment paradigm and to relate it with other functional skills (motor skills). The objectives of the project were: 1) To develop a novel task to depict eye-hand coordination at different depths (in three dimensions), namely the ReGraD task, which involved motion analysis of the hand during the task execution. Data was collected to test its reliability over two time points. 2) To map the relation between vision, attention and motor disorders in children and young adults (6-35 years old) with paediatric amblyopia, using the ReGraD task. 3) To test the efficacy of a treatment involving novel games in a 3-dimensions virtual reality headset (in collaboration with the company Vivid Vision Inc, USA).

Цел на проекта

To reach for a bottle (motor), we need to be able to identify its properties (attention) and know where in space it is located (3-dimensional (3D) vision). This cascade is however impaired in some developmental disorders of vision, like Paediatric Amblyopia (PA) or lazy eye. With this proposal, I first aim to gain insights in the underlying deficits of PA, by combining expertise from the vision sciences, cognition and motor control research fields. These insights will provide a deeper understanding of the core deficits of children with PA, and their inter-relationship. I will put specific emphasis on the study of 3D vision and its impact on selective attention and motor planning, as these have previously been understudied, despite their clear impact on vision and potential coexistence in PA. Second, I aim to test the efficiency of a novel, ethological, and engaging 3D games in a virtual reality environment to improve vision in children with PA. Thirdly, I will examine whether the improvements on vision are accompanied by changes in attention and motor control and which are the underlying brain mechanisms of such improvements. Lastly, by using artificial intelligence approaches on treatment outcome, I will be able to provide guidelines toward a personalized medicine tailored to the patient’s needs. To succeed in this project, I will (i) combine measures of the traditional basic vision tests with novel functional vision evaluation, (ii) quantify uni- and multisensory selective attention with behavioural and brain imaging (electrical neuroimaging) methods, (iii) integrate sensor-based measures of motor planning during reaching, (iv) develop a novel, efficient and ethological virtual reality training to recover 3D vision in children with PA. This project will accumulate clinically relevant results that will be disseminated to the scientific community and communicated to the clinicians and the children’s families through a variety of activities.
