August 31, 2022 updated by: Ildar Fakhradiyev, Asfendiyarov Kazakh National Medical University
The aim of this study is to evaluate the quality of life of AMD patients related to vision using the short version of the National Eye Institute Visual Function Questionnaire (NEI-VFQ-25), patients' social support, and their relationship with demographic and clinical variables.

Study Overview

Detailed Description

Background and study aims. Age-related macular degeneration (AMD) is the most prevalent chronic progressive ocular disease. It has been shown in several studies that AMD affects the quality of life of patients. The aim of this study is to evaluate the quality of life of AMD patients related to vision using the short version of the National Eye Institute Visual Function Questionnaire (NEI-VFQ-25), patients' social support, and their relationship with demographic and clinical variables.

Who can participate? Patients with AMD, who wish to participate, will be recruited. Patients will be recruited from three locations of the Kazakh Scientific - Research Institute of Eye Diseases in Almaty, Nur-Sultan and Shymkent.

What does the study involve? The study involves collecting demographic data of the participants, collecting baseline visual testing data from medical records, filling out of the NEI-VFQ-25, and answering two yes/no questions related to the social support and reliability of social support.

What are possible benefits and risks of participating? Assessment of quality of life and social support of the AMD patients is a first step of developing targeted psycho-social support programs for AMD patients.

Where is the study run from? Patients will be recruited from three locations of the Kazakh Scientific - Research Institute of Eye Diseases in Almaty, Nur-Sultan and Shymkent.

When is the study starting and how long it is expected to run for? Start date 03/02/2020. End date 27/08/2022.

Who is funding the study? No funding for this study. Who is the main contact? Principal investigator: Inara Ismailova; +380 73 200 0688; i.ismayilova@gmail.com

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Quality of life of AMD patients
Time Frame: at the recruitment to the study
Vision related Quality of life (QOL) of AMD patients related to vision assessed by NEI-VFQ-25 total score at the recruitment. NEI-VFQ-25 has 38 questions with multiple choice answers, each rated 0,25, 50, 75 or 100. The overall score is measured as a mean of all answers
at the recruitment to the study

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Social Support
Time Frame: at the recruitment to the study
Percentage of AMD patients with Social Support. Social Support of AMD patients at the recruitment assessed by answering a yes/no question.
at the recruitment to the study
Reliability of Social Support
Time Frame: at the recruitment to the study
Percentage of AMD patients with a reliable Social Support. Reliability of Social Support of AMD patients at the recruitment assessed by answering a yes/no question.
at the recruitment to the study
Relationship between QOL and social support
Time Frame: at the recruitment to the study
Correlation between the overall quality of life of AMD patients and demographic, visual characteristics, and social support tested with multiple linear regression model. The Hosmer-Lemeshow goodness-of-fit test will be used to test the model's fit. All tests will be two-tailed with a significance level of 0.05.
