Scotoma
Also known as: Blind Spot, Visual Field Defect
An area of partial or complete loss of vision within the visual field, surrounded by areas of relatively normal or less affected vision. Scotomas can result from conditions such as macular degeneration (central scotoma), glaucoma (peripheral scotomas), or retinal damage. People with scotomas may not be aware of them because the brain can fill in missing information. In low-vision rehabilitation, training may focus on developing scotoma awareness and strategies like eccentric viewing to work around the affected areas.
