The five patterns of vision loss are central field defect, peripheral field defect, reduced acuity, reduced contrast sensitivity, and combination.

The five patterns of vision loss are central field defect, peripheral field defect, reduced acuity, reduced contrast sensitivity, and combination.

• A. Not sure
• B. Depends on context
• C. True
• D. False

Answer: (C)

The main idea is that vision loss can present in several functional patterns that clinicians use to describe a patient’s remaining vision. Central field defect reduces vision in the center, affecting reading and recognizing faces; peripheral field defect reduces the outer boundaries of vision, impacting spatial awareness and mobility; reduced acuity means blurred or less sharp vision; reduced contrast sensitivity means trouble distinguishing similar shades, especially in low-contrast situations; combination means more than one pattern is present. These five patterns are widely recognized as the common categories used in vision rehabilitation to guide assessment and intervention, so the statement is true.
