A
If the patient is unable to identify movement that the examiner perceives, a defect in the visual field is presumed. An area of depressed vision within the visual field can be caused by tumors, strokes, glaucoma, or retinal detachment. Hyperopia is farsightedness in which light rays focus behind the retina. A nutritional deficiency can cause defects in color vision. Nearsightedness or myopia occurs when light rays focus in front of the retina.
