Përmbledhja	The Impact of Vision Impairment (IVI) scale is a quality-of-life instrument designed specifically for patients with significant vision loss (low vision) to measure the psychological, functional, and social burden of visual impairment. Developed by Wolffsohn, Cochrane, and colleagues (2000), the IVI captures domains including emotional impact (distress, frustration), functional limitations (mobility, ADLs), social participation, and role fulfillment in populations with moderate to severe vision loss where generic or mild-vision-focused instruments are insensitive.	The GQL-15 is a 15-item, disease-specific quality of life questionnaire designed to measure the impact of glaucoma on patients' daily functioning and psychological well-being. Developed by Nelson, Aspinall, and colleagues in the UK (1998), the GQL-15 emphasizes glaucoma-specific concerns—visual field loss, peripheral vision, lighting sensitivity, and falls risk—making it a sensitive complement to generic or broader vision-related instruments in glaucoma populations.
