Needs of patients with age related macular degeneration
Houdková, Eliška ; Jirkovský, Daniel (advisor) ; Haluzíková, Jana (referee)
This bachelor's thesis deals with the area of specific needs in patients with age-related macular degeneration (AMD). Objectives: The aim of this thesis is to provide an overview of the changed needs of patients with AMD. Methods: To achieve the aim of the thesis, a questionnaire survey was conducted. The target group of the survey were patients undergoing anti-VEGF therapy at an unnamed eye clinic. A total of 70 questionnaires were included in the survey. Results: Based on the statistical evaluation of the data, it was found that AMD significantly affects the lives of respondents in many areas. The majority of respondents identified independence and self-sufficiency as the most affected aspect of their lives. More than half of the respondents (55.71 %) have problems with mobility and everyday activities. AMD also negatively affects the mental health of patients, 70 % of respondents are afraid of depression or anxiety. Respondents find meaning and fulfillment in life, especially in the areas of family and friends relationships, leisure activities, spiritual development, education, gratitude, and a positive attitude towards life. Conclusion: AMD has a complex impact on the lives of patients. It is important to provide patients with AMD with high-quality and accessible care that includes not only...

Potential of mesenchymal stem cells and nanoparticles in the treatment of retinal disorders
Kettner, Ondřej ; Heřmánková, Barbora (advisor) ; Filová, Eva (referee)
Retinal degenerative diseases are recognized worldwide as one of the predominant causes underlying irreversible visual impairment and even blindness. The current standard treatment has helped in both the prevention and supportive treatment of several pathologies, especially if they relate to the retina. However, many of these methods are rather invasive in terms of procedure with the subsequent possibility of infection, inflammation or even retinal detachment with the potential risk of vision loss. These restrictions represent a significant cost to patients' quality of life and also have an economic impact on the healthcare system, so new treatment options are being sought. Mesenchymal stem cells (MSCs) are a promising cell therapy tool for the treatment of many previously untreatable defects and diseases. In addition to MSCs, the use of nanoparticles and nanofibrous carriers is currently being studied in the diagnosis and therapy of retinal diseases. Combining the immunomodulatory and regenerative properties of MSCs and nanotechnologies offers a promising therapeutic strategy for a number of diseases. This thesis is therefore devoted to the current state of the use of nanomaterials, MSCs and their combination that may provide new opportunities in the treatment of retinal degenerative diseases.

Immunomodulatory and regenerative potential of mesenchymal stem cells in the treatment of degenerative retinal disorders in mice
Palacká, Kateřina ; Heřmánková, Barbora (advisor) ; Grobárová, Valéria (referee)
Retinal degenerative disease are the leading cause of vision loss in adult patients. Important role in the development of these types of disease play gradual death of retinal cells and an inflammatory reaction that leads to the production of cytokines, formation of inflamasome, increased angiogenesis and scar formation. These pathologies result in irreversible degeneration of retinal cells. Retinal pigmenetd epithelium cells, photoreceptors and ganglion cells are the most frequently damaged cell types in this conditions. The available treatments are currently very limited and effective only at the early stages of the disease. Therefore, the use of stem cell- based therapy could be a promising option. For therapeutic purposes it would be possible to use mesenchymal stem cells (MSCs) which may be isolated for example from bone marrow or adipose tissue. MSCs are capable of production of neuroprotective factors, differentiation into the variety of cells types and regulation of immune response. In this study we tested the therapeutic potential of MSC administered locally to the damaged retina in an experimental model of retinal degeneration. We focused on the protective effect of MSCs on photoreceptor cells, regulation of the local immune response and expression of genes for cytokines involved in...
