adventitious visual impairment

partial or total visual impairment that results from injury or illness following a period of normal visual ability. Onset of the impairment can produce severe grief, mourning reactions, and dependency. As a consequence, any residual visual capacity may not be used effectively, exacerbating psychological and social-adjustment problems. Also called acquired visual impairment. Compare congenital visual impairment.
