Limited Visual Field

Visual field deficits result in a limited visual field. These cannot usually be be fixed with glasses or surgery. Field loss can be described as a scotoma (a blind spot), hemanopsia (half of the field is missing in one or both eyes), or tunnel vision (the field is constricted to central vision). Visual field refers to the total area that is visible to a person while looking at a fixed central point. Individuals with conditions such as glaucoma, macular degeneration, retinitis pigmentosa, and cataracts may experience limited field of vision. This can impact both peripheral and central vision. Employees with visual field loss may have difficulty navigating around obstacles in the workplace, and may need accommodations to assist with wayfinding and mobility.
