Our Goals

The main goal of the project is to design, assess, and extensively interpret a deep learning (DL)-based decision support system aimed at early, accurate detection of AMD. We will focus both on detecting the presence of the disease and on grading its different stages. To achieve this goal, different architectures from diverse DL approaches will be implemented. Furthermore, in order to interpret, from a clinical point of view, all the detected risk factors leading to the detection of AMD from fundus images, a thorough analysis of every model will be conducted using XAI techniques.

Specific objectives

Objective 1

To build up a private database composed of novel fundus images. This goal includes the capture, organization, and manual annotation of the images.

Objective 2

To design and optimize high-performance models for AMD diagnosis based on novel individual DL approaches.

Objective 3

To explore and develop novel architectures by combining different DL-based approaches.

Objective 4

To evaluate the detected patterns inherent to input fundus images linked to the presence and severity of AMD and its consequences.

Objective 5

To interpret and explain the diagnostic decisions of the DL models based on the detected risk factors.

Expected impact

Scientific-technical impact

  • Development of novel high-performance decision support-systems based on the emerging DL techniques.
  • Identification of novel image landmarks in fundus images for an early detection and grading of AMD.
  • Clinical analysis of the results through the extensive interpretation of automated models.
  • New software applications for ophthalmology research with potential to be integrated in the devices of leading manufacturers.

Social and clinical impact

  • Reducing waiting lists in ophthalmology.
  • Development of automatic methods that contribute to the early diagnosis of AMD and that help prevent the evolution of dry AMD to wet AMD.
  • Gaining insight into the pathophysiology of AMD through the extensive interpretation of automated models.
  • Evaluation of the final diagnostic/management methodologies in clinical practice with real patients.
  • Publishing the results in a website, social media, open access repositories and scientific divulgation magazines to maximize the dissemination in the general population.
  • Employment creation.

Economic impact

  • Decreasing the total number of appointments with the specialist and associated direct costs.
  • Savings in human and material resources, allowing to be assigned to more demanding tasks.
  • Savings in indirect costs related to health, since early diagnosis and adequate therapy would improve the quality of life of people with AMD.

Knowledge transfer and results exploitation

Action 1

Identification of results with high potential to be exploited/transferred, including but not limited to: (i) New algorithms (software) to detect AMD based on DL methods; (ii) New algorithms (software) for the management of patients with AMD based on XAI methods.

Action 2

Involving possible observing promoters in the publication and dissemination tasks.

Action 3

Assessment of the feasibility of transferring the automated decision-support systems to (i) clinical practice environments and (ii) companies in the field of ophthalmological services/therapies, in order to provide added value to the patients.

Action 4

Collaboration with the Office for the Transfer of Research Results (OTRI) from the UVa, which will provide advice and support on different ways of transferring and exploiting research outputs.

Action 5

Identification of the scientific-technical knowledge with potential for being protected by means of intellectual property rights. Assessment of the feasibility of applying for software licenses/patents.

Action 6

Development of a careful market analysis in order to identify strengths and opportunities, as well as potential barriers and threats to exploit or transfer the results. This would include the contact with health institutions, private companies, and service providers in the field of ophthalmological medicine.
