In this paper we consider development of a user-friendly medical record to follow-up treatment of wet AMD (age-related macular degeneration) with VEGF (vascular endothelial growth factor) inhibitors. A systematic user-centered design process is described that is realized together with ICT-experts and doctors. We will underline especially ways to solve challenges relating to multidisciplinary communication of all parties involved. The developed application tracks macula condition and medical treatments and can display them in a user-friendly fashion. Data searches can be done for a dedicated patient or overall patient histories. Modern ICT offers also several ways to process and represent the collected big data such that significant sickness development trends are easier to recognize and follow. Usability feedback mechanisms for health-care personnel are also discussed in the various application development phases that should be used to ensure user application quality and the continuous quality development of the respective caretaking practicalities.
